The Best Pregnancy TestUpdated April 8, 2019 We have added test notes for our also large selection.Your guideLeigh Krietsch BoernerShare this review The result shown in a pregnancy test can be the change of life, so you need a clear and accurate result. After more than 50 hours of research, talking to an expert on pregnancy hormone (HCG) and an ob-gin, drinking too many cups of tea, and peeing in more than 60 sticks and strips, we believe that the manual exam is the pregnancy test to be taken. If you prefer to buy bulk, we have a recommendation that it cost less than a quarter each at the time of publication, although you may want to verify your results using one of our other peaks (or visiting your doctor). Our Choice The First Early Response The Manual Results Test is the most sensitive pregnancy test that can be purchased. It gives accurate results as or faster than most of the tests we consider and is as easy to read as a digital test. Purchase Options The manual test, the most sensitive free sales pregnancy test, according to the US HCG Reference Service, emerged as the clear winner of our research and testing. We find that it gives a clear result quickly, and its ergonomic design makes the handle easier to keep compared to the wands in comparable tests. AdvertRunner-up This test has a pleasant, usable design, with a large sponge tip, but it is harder to hold and less sensitive than the manual test of the first response. Purchase Options In the incredibly unlikely case that a manual test cannot be found, our execution option is another manual test, the . It is well designed, with a large absorbent pad and a thin grip end, but it is not as easy to grab as the First Answer. It is also not as sensitive and cannot pick up very early pregnancies, as well as the manual test of the First Answer. Also large and simple, can be blown through a ton of these strip tests without spending much. But they don't have the accuracy verified by the more expensive test lab. Purchase options*At the time of publication, the price was $7. If you anticipate frequent tests and want a cheap, adjusted test that you can buy bulk, we suggest the . These are the thin strips that you immersed in a cup of pis. We don't have independent precision information about these, but they've gone well in our own (limited) tests, and out of the striped-type tests we tested, ClinicalGuard was by far the cheapest. These strips cost almost half of the comparable tests and less than one tenth of the cost of a single manual test.

ResearchWhy You Must Trust UsFor this guide, we interviewed Laurence Cole, PhD, a researcher who has long studied pregnancy tests at home, and , an obstetrician (ob-gyn) in Los Angeles. I am a scientific writer with a doctorate in chemistry and 10 years of laboratory experience, so I can make solutions and test them accurately (although I am not used to doing it with my own pis). I've also been pregnant twice, including while writing the original version of this guide, so I know what it is to take a pregnancy test when you really want to know what it says. How Home Pregnancy Tests Work Pregnancy tests at home measure the small amount of hormones the body produces when a fertilized egg is implanted and begins to grow. Specifically, they contain antibodies that can collect the presence of human choral gonadotropin (hCG) in pis. Two types of HCG are important in early pregnancy. The first, hCG, is a hormone responsible for forming the mechanism by which the placenta gives nutrients to the fetus. The second hyperglycosylated hCG (or hCG-h), is a completely different and unrelated molecule. Both hCGs differ when they are present in pis during early pregnancy. In early pregnancy (weeks three and four) only hCG-h is present, Cole said. Regular HCG does not occur until you are pregnant four to five weeks. approximately every 72 hours in early pregnancy, reaching its peak about eight to 11 weeks, then leveling for the rest of the pregnancy. HCG levels in the urine can also vary a lot. If you're pregnant and it's been three weeks since the beginning of your last period, you can have anywhere from 5 to 50 mIU/mL on your step. (That's in Milli-International Units per milliliter, a standardized unit that doesn't really tell you much. Regardless, this is how the levels of this matter are measured.) At six weeks of its last menstrual period, this spread is from 1,080 to 56,500 mIU/mL. According to studies and other researchers, hCG is present at low levels in the body even when a person is not pregnant, so the tests cannot be too sensitive or may mistakenly record a false positive. False negatives, where you are pregnant but getting a negative reading on a pregnancy test, are much more common than false positives. Another way you could get a false positive is if you have what is called a . This is a pregnancy that does not develop beyond the early stages, often resulting in miscarriage around the time that menstrual bleeding would be expected. False negatives, where you are pregnant but getting a negative reading on a pregnancy test, are much more common. According to Dr. Serna in Cedars-Sinai, this can happen when you take a test too early and cannot pick up at hCG levels on your pis yet. If you think you may be pregnant and take the test before a lost period and get a negative result, wait a week and take the test again. To get the most accurate results, try after losing a expected period. The longer you wait after a lost period, the more accurate the test will be. (To be sure that a pregnancy test at home works properly, look for what is called a control line: This should appear if a second line appears, which indicates the detection of hCG.) For more accurate pregnancy tests, visit your doctor. How they chosePregnancy tests should be four things: sensitive enough to pick up early, easy to use, easy to read and relatively cheap pregnancy. Is this combo too much to ask? No. Luckily, there is a lot of scientific data on the accuracy of pregnancy tests at home. That's the case, we didn't do our own precision tests, but we depended on the experts. And the most expert we could find was the biochemical Laurence Cole, who when this article was originally published in 2015 led the U.S. hCG Reference Service at the University of New Mexico. He has conducted extensive research on pregnancy testing at home and hCG, including evaluation of pregnancy tests at home most commonly available at pharmacies. He's found that First Response digital and manual tests are the most sensitive because they can detect hCG-h, the kind of hCG that women produce only very early on in pregnancy, before than other drugstore tests. According to (PDF), Clearblue Easy and EPT are less sensitive than the First Response, but more sensitive than other tests. These tests also detect hCG-h but not as well as First Response. In addition to precision, we consider the usability, readability and cost of testing. Some pregnancy tests at home require you to pee in a clean cup and then a strip is dipped into the urine. Others are housed in plastic sticks and have absorbing tips that you can urinate directly, or dip if you choose. We consider both types of tests, finding that the latter is easier to use and read. Most manual tests cost about $4 to $6 each. Digital testing, which shows a "positive" or "negative" result written on a small screen, tends to be more expensive than manual versions without a screen. After taking a few separate digital tests, we learned that they are actually in manual testing, only the digital test has a sensor to detect the dark line for you, often about a minute after most people could ocular it to themselves using a manual test. Until recently, we had ruled out evidence for which we had no independent precision data. However, readers have been asking us about cheap, scratch-type tests that you can buy online bulk, so we compare these to determine the best option in this category even though Cole told us that these are generally less sensitive than the most expensive stick tests. How We Have Proved Although sensibility is the most important thing in a pregnancy test, it is not the only thing. The design is also important: how easy it is to use and how easy it is to read. So that's where we focus our tests. I took six of each of our contenders and put them through the rhythms. I tried them several times using medianverization methods and pee in a cup and drip. Since I was nine months pregnant at the time of the test, I jumped the various strips in the water (and, in one case, my husband peed in one) to confirm the known negative results. I also diluted my own urine a thousand times in water to see how it was a bit positive. To simulate potential user error, I kept every test backwards while waiting for the results (a great not, according to the packaging), just to see what happened. In short: I have totally abused these things. Two female officials, none of whom were pregnant at the time of the test, also tested each of them both in the middle of the current and in the decomposition methods and added their comments. In our experience, none of these tests gave what is known as , which are lines that can sometimes appear in manual tests and be confused by a positive result. Our Selection: First Response Our Choice The First Early Response The manual test results is the most sensitive pregnancy test that can be purchased. It gives accurate results as or faster than most of the tests we consider and is as easy to read as a digital test. Purchase Options Due to its high sensitivity, accuracy and quick results, we believe that a manual pregnancy test is the one you want to get. It's the most sensitive pregnancy test you can buy. It is as easy to read as a digital test and much less likely to give you an error message. In addition, in our tests it gave the clearest positive reading to a very diluted solution of positive footing for pregnancy. The results arrived quickly, taking only 40 to 45 seconds on average. Unlike the Clearblue and EPT tests, the First Response test does not have a separate window for a control line, but we find the strong and dark lines easy to decipher for both positive and negative results. To imitate the first days of pregnancy, I have prepared a very diluted solution of the positive urine of the hCG. As can be seen in the photo, the First Response manual test showed a very clear positive response with a strong line of fucsia, while the other pregnancy tests barely recorded weak blue marks. The current First Response manual test has an ergonomic and easy to use shape. It has a good wide tip, so hitting that target while on the toilet is a little easier, if you decide to use the medium current method. It also has a curved grip with gripping texture on the back that makes it easy to keep and collect from a table. In addition, the handle is large enough to wrap the whole hand, not only pick between the thumb and the forefinger. That made me feel like I was less likely to leave everything in the toilet bowl. Since our original test in 2015, we have not found a pregnancy test at home more sensitive or easier to use and read. Wirecutter employees who have used the First Response since 2015 have found that it actually collects in hCG and shows a "pregnant" result before the First Response and Clearblue digital tests. Flaws but not negotiators The first test of Answer is easy to read, although the variable darkness of the two lines can be a bit confusing. In a test, with full strength, positive urine, the pink line to the right was much, much lighter than the positive line. (In the pamphlet it says this can happen.) This changed when I tested diluted urine solutions. In this case, the right line was much brighter than the positive line. However, there was no mistake in the positive line. Some people have complained that the curved window of the redesigned test makes it harder to read. Depending on how the light hits that plastic window, there may be a reflection that some people might be mistaken for a second line. It is better to examine the results of any pregnancy test in different lighting conditions. Runner-up: Clearblue Rapid DetectionRunner-up This test has a nice, usable design, with a big sponge tip, but it is harder to hold and less sensitive than the first response manual test. Shopping Options Although not as sensitive as the First Answer manual test, the manual test is a good backup option if the First Answer is not available. It has a thin, easy-to-hand handle that we find makes it better to keep than the EPT test (although not as easy to maintain as the First Answer). Like the First Response test, it has a fat tip, making it a generous target for a pis current. The absorbing pad in the Clearblue manual test becomes pink when wet, so you can see it when it starts working. He gave me a positive Clearblue test in as little as 10 seconds on one occasion, but the average was more than 45 to 50 seconds, either positive or negative. Clearblue digital tests took between 11⁄2 and 3 minutes to give results. It's also great: HCG ClinicalGuard Pregnancy Test Tapes Also large and simple, can be blown through a ton of these strip tests without spending much. But they don't have the accuracy verified by the more expensive test lab. Purchase options*At the time of publication, the price was $7. If you want to go really, really basic and save money by buying a lot of tests, we suggest the , with a caveat: We don't have independent precision information about these tests as we do for our other choices. However, they have found that these test strips are accurate, as did a Wirecutter editor for whom ClinicalGuard test strips gave positive results faint but detectable three days before a expected period and clear negative results when she was not pregnant. The strip tests use the same technology as the manual tests we recommend and show the results in a similar way; they simply lack the plastic housing that facilitates the use and reading of manual and digital tests. You can't pee directly on these. Instead, you plunged them into a cup of urine. The advantage is that strip tests normally cost less than a tenth of what our other elections cost. According to Cole, some cheap strip tests can collect hCG only when it is about 25 mIU/mL, so not so early in pregnancy, depending on the person. However, hCG levels can vary a lot from pregnancy to pregnancy, anywhere from 5 to 50 mIU/mL for most people when they are three weeks (or a week after a lost period). So the strip tests can accurately report the true positive result of one person before, but not another. Of the three strip tests we've seen (ClinicalGuard, Wondfo and Easy@Home), ClinicalGuard was the cheapest one. Everything else—the size of the strip, the time to take place, the ease of use—was exactly. Him. Same. Seriously. If prices change, simply go to the cheapest test, but be aware that you may end up wanting to confirm the results with a test that is known to be highly sensitive, such as the First Answer (or a visit to your doctor). Manual tests against digital pregnancies As for manual digital testing vs., there is really no contest: Manuals are the clear winners in the price and are as easy to read as digital in our experience. This surprised me. Before working on this guide, when shopping for pregnancy tests I made a bee for digitals. I didn't want any ambiguity about a positive or negative result. I wanted the thing to tell me a clear "yes" or "no". Digital testing is really just manual testing with a battery and sensor that reads the lines for you. But I've found since then that manual tests give a clear answer. The result was not questioned when using any of the manual tests evaluated for this guide. In addition, manual tests, which do not contain circuits, are much less likely to fail in you. They are also much faster to give a result: About 40 seconds on average against 3 minutes? Yeah. In the big scheme of things, 3 minutes is not long to wait. But when it comes to taking a pregnancy test, it is most likely that you prefer to know the result as soon as possible. The curious thing is that digital tests are only manual tests with a battery and a sensor that reads the lines for you. I opened the three digital test marks, and they look like the inside manuals. See that strip in the previous picture? You think it's familiar? Yeah, that's the same as what manual tests show you. There is a small sensor in the row of three squares a little to the right where the test strip is up (I peeled it again from there). So basically, just read those lines for you and tell you, in writing, if the strip detected hCG. But it takes more time to do this than is likely. Manufacturers themselves point out that digital testing tends to be less sensitive than manuals. According to the boxes of all these tests, these are the statistics obtained from laboratory tests: First response: The manual test collects 76 percent of pregnancies five days from the expected date of the period, while the digital test says yes to only 60 percent of the people who are really pregnant at the time. By the time it's the day you wait for your period, both give a positive to more than 99 percent of those who are pregnant. Clearblue: Manual tests give a positive 56 percent of people who are really pregnant four days before a lost period, and the digital gives a positive 51 percent. These numbers are 98% and 95%, respectively, for the day of a lost period. EPT: Four days before a lost period, manual tests give a positive result 53 percent of the time, just like EPT digital testing. On the day of a lost period, these numbers jump to 99 percent. These results reported by the company reflect Cole's results. He found that the manual test of the First Response was the most sensitive of all tested. The competition gave me a false negative. I also had technical problems with a second test, which finally gave me a positive but only after waiting 61⁄2 minutes. The other tests gave results in 3 to 31⁄2 minutes. The instructions say it should take 3 minutes. He's a little clunkier and heavier than the manual test. Both were very easy to read, but the manual test gave results faster. The manual test, aka the "Error Proof Test", was the first free sale pregnancy test. (His name really comes from "pregnancy test.") In our tests, he had a line of control that was on the side, although he later corrected. Manual tests had a speed of 20 to 30 seconds, although it usually took up to 40 seconds to show up the test line. (EPT suggests not to read the test before 2 minutes.) He was the fastest batch and gave me results in less than 2 minutes. (Digital testing is supposed to be read after 3 minutes, although the pamphlet says some results appear in as little as 1 minute.) However, its design is clunky, and is not as sensitive to hCG as First Answer. Dollar Tree and other discount stores often carry $1 pregnancy tests like this one. As with the test strips we recommend from ClinicalGuard, you should first pee in a clean cup to use this test. (You can't use the in-stream method as you can with vand-style manual tests.) Although we do not have independent precision information, customer opinions indicate that this test has collected true positives after lost periods. But it costs about four times more per test compared to ClinicalGuard strips. The tests and strips are quite identical. The strips look exactly the same, and the addresses included are exactly the same, except that the Easy@Home addresses have their logo at the top. At the time of this writing, Easy@Home tests were cheaper than Wondfo testing, but both were more expensive than ClinicalGuard., First Response launched its Pregnancy Pro test with Bluetooth, which has the ability to match with a smartphone. In addition to being loaded with a lot of options that are of dubious utility (, where you are supposed to select "Educate Me," "Intertain Me," or "Calm Me" options while waiting) this new test costs more than three times the price of the First Answer manual test. There's no reason to spend the extra money. Footnotes A quick intersection on pregnancy terminology: has anyone heard that they are pregnant for x weeks? Doctors count these weeks from the first day of the last period of the person before becoming pregnant. Because ovulation occurs about two weeks after this date, you basically get two weeks of free pregnancy, as far as terminology is concerned. So a person who has a period beginning on 1 February and gets pregnant in his ovulation cycle immediately after that can say that they are pregnant four weeks on 1 March. The day of pregnancy varies from person to person, you do not get pregnant on the day you ovate, but later, after the egg is fertilized (which may take a few days) and fertilized egg implants (which may take up to five days after fertilization). For dilution 1, I took 5 ml of my pis and added 95 ml of water. Then I took 5 ml of this solution and added it to 95 mL of water for dilution 2. I dipped the tests on both for the "diluted" tests. Unfortunately, I didn't know the hCG concentration of my pis at this point. In late pregnancy, which is what it was when I did the tests, a woman may have anywhere from 3,640 to 117,000 mIU/mL of hCG in her urine. It was not practical to make my hCG levels tested to know the exact amount. But that means dilution 1 had a level of hCG from 182 to 5,850 mIU/mL, and dilution 2 had a level of hCG from 9.1 to 292.5 mIU/mL. I guess it was to the lower end, because the evidence was just positive.
