Things To Consider Before Buying A Pregnancy Test
Despite small differences between them, all over-the-counter pregnancy tests work basically the same way. They detect a hormone called human chorionic gonadotropin, or hCG, in urine, which the body starts producing when a fertilized egg implants in the lining of the uterus and an embryo begins to grow. Even urine-based pregnancy tests used in doctors offices tap the same mechanism. Anything thats detecting the pregnancy hormone from the urine is going to be the same, whether you get it from us, or if you get it from a drug store test that you take at home, says Dr. Sarah Horvath, an obstetrician-gynecologist at Penn State Milton S. Hershey Medical Center.
There are two main forms of intact hCG: regular hCG and hyperglycosylated hCG , which is more common in very early pregnancy. Most tests should detect total hCG, including both types, though some research suggests that many dont detect hCG-h as effectively.
Scientifically, pregnancy screenings are a type of test called a lateral flow test. After a sample is collected, it flows to an area with a line of lab-manufactured antibodies that capture a molecular part of hCG called the beta subunit. If it is detected, the hormone will also bind to a second antibody that captures the alpha subunit, the other half of the hCG molecule, which turns the test line a color. The sample will also flow to a control line, which will react to the presence of any urine no matter what to indicate you have used the test correctly.
Our Pick: First Response Early Result
*At the time of publishing, the price was $13.
For its high sensitivity, accuracy, and speedy results, we think a First Response Early Result manual pregnancy test is the one youll want to get. Its the most sensitive over-the-counter pregnancy test you can buy. Its 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 dilute solution of pregnancy-positive pee. Results came in quickly, taking only 40 to 45 seconds on average.
Unlike the Clearblue and EPT tests, the First Response test doesnt have a separate window for a control line, but we found the strong, dark-pink lines easy to decipher for both positive and negative results.
To mimic the earliest days of pregnancy, I prepared a very dilute solution of hCG-positive urine. As you can see in the photo, the First Response manual test showed a very clear positive response with a strong fuchsia line, while the other pregnancy tests barely registered faint blue marks.
Since our original testing in 2015, we havent found a more sensitive nor easier-to-use-and-read home pregnancy test. Wirecutter staffers who have used the First Response since 2015 have found that it indeed picks up on hCG and displays a pregnant result sooner than digital tests from First Response and Clearblue.

What Is The Most Accurate Pregnancy Test
In the largest study of over-the-counter pregnancy tests to date, First Response proved to be 97 percent accurate from the day of your missed period for both its digital and manual line tests.
However, the study was conducted in 2011 and only compared six over-the-counter tests from three major brands. Many brands may have changed their technology since. Newer direct-to-consumer brands that have burst onto the scene, as well as other brands not included in the study, may prove to be just as accurate.

When Should I See A Doctor For A Clinical Pregnancy Test
Most women who have a positive pregnancy test should wait a week or two before calling the Ob/Gyn office for a pregnancy blood test. We suggest waiting because the rate of early pregnancy loss is high, and its possible that it might have been a chemical pregnancy.
However, women with a history of ectopic pregnancy or current abdominal pain should call the doctor right away to be examined. Ectopic pregnancies implant outside of the uterus and produce hCG, resulting in positive pregnancy tests. However, these pregnancies can cause abdominal bleeding and prompt medical care is necessary. Women who have congenital heart defects or other chronic physical or mental health conditions should also see a doctor right away because treatment plans or medications might need to be altered to protect the woman and the fetus.
Advances in home pregnancy tests give women greater insight into whats going on in their bodies sooner than ever before. No matter what a womans childbearing plans might be, its essential to get quick, accurate results at home so she can plan her next steps accordingly.

How Accurate Are Home Pregnancy Tests
Home pregnancy tests are generally considered very accurate so if you get a positive result, give yourself permission to celebrate.
Still, its important to note that, while very rare, false positivesare possible. Certain fertility drugs contain hCG and can result in a positive reading when youre not actually pregnant, warns Frederick. An expired test can also lead to a faulty reading. False negatives can happen too. Most commonly, this would be the result of testing too early.
Keep in mind that pregnancy tests may have slightly different sensitivity levels. One might be positive and another negative on the same day in a woman who is newly pregnant, and the difference is the quality and sensitivity of the pregnancy test, says Sara Twogood, MD, an ob-gyn at Cedars Sinai Medical Center in Los Angeles and author of Ladypartsblog.com. Still, home pregnancy tests purchased at stores and pharmacies are regulated by the FDA, so suffice to say, most are considered very reliable.
Q: Can You Be 5 Weeks Pregnant And Test Negative
Probably not. Interestingly, Ann Gronowski, a pathologist at the University of Washington in St. Louis, and her colleagues examined in a series of studies how some urine-based pregnancy tests used in healthcare and hospital settings can give false negative results five or more weeks into pregnancy. This is because of a flaw in some tests in which they fail to detect a degraded form of hCG, that becomes more prevalent in the body after five or six weeks of pregnancy. However, this likely isnt a concern with at-home tests. If you think you are pregnant but continuously test negative, you should talk to a healthcare provider.

How Home Pregnancy Tests Work
Home pregnancy tests measure the small amount of hormones that the body produces when a fertilized egg is implanting and beginning to grow. Specifically, they contain antibodies that can pick up the presence of human chorionic gonadotropin in pee.
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 , is a whole different, unrelated molecule.
The two hCGs differ in when theyre present in pee during early pregnancy. In very early pregnancy only hCG-h is present, Cole said.1
Regular hCG is not produced until youre about four to five weeks pregnant. Amounts of this hormone double roughly every 72 hours in early pregnancy, reaching their peak around eight to 11 weeks, then level off for the remainder of the pregnancy. Levels of hCG in pee can vary a lot as well. If youre pregnant and its been three weeks since the start of your last period, you can have anywhere from 5 to 50 mIU/mL in your pee. At six weeks past your 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 cant be too sensitive or they might erroneously register a false positive.
False negatives, where you are pregnant but get a negative reading on a pregnancy test, are much more common than false positives.
Q: How Long Do Tests Take To Show Results
When you are taking a pregnancy test, how long you have to wait to see results depends on the test. It could be less than a minute, five minutes, or as long as 10. With manual tests, try not to lose your patience and decide that the test must be done before the time it says on the package. Likewise, you cant necessarily trust the results if you pull a test you took out of the trash hours later: Some manual tests will have a line appear after a while that does not reflect a positive result. This is a so-called evaporation line, which is just a mark made when your urine evaporates from the test and can be mistaken for a positive result.
