Are Rexall Pregnancy Tests Accurate (2024)

FAQs

How soon can you take a Rexall pregnancy test? ›

Home pregnancy tests can usually detect a pregnancy the day your period is due (about 2 weeks after you ovulate). To do a home pregnancy test, follow the instructions on the leaflet.

A positive result will have a test line that runs from the top of the test window to the bottom with the same thickness and color as the control line. An evaporation line will be a grayish white mark that appears after ten minutes. The best way to know if you are pregnant is to test again tomorrow.

When the test line is visible but colorless, this is called an “evaporation line”. Evaporation lines rarely indicate pregnancy and are considered a false-positive result.

The pregnancy tests you get at the drugstore work 99 out of 100 times. They're just as accurate as a urine pregnancy test that you'd get at a doctor's office. Pregnancy tests work by checking your urine (pee) for a hormone called human chorionic gonadotropin (HCG). Your body only makes this hormone if you're pregnant.

For many of these tests, HCG can be detected in your urine about 10 days after conception. However, taking it after you miss your period reduces the chance of getting a false-negative result. A missed period typically happens around 14 days after conception.

Proov Check Early Pregnancy Test: Proov Check is one of the few tests that can detect pregnancy hormone levels as low as 5mIU/mL, which allows you to check for pregnancy as early as five days before the expected period, according to Dr. Flisser.

If you want to save time and money, your best bet is to wait longer than 12 hours before taking another pregnancy test. But there are a couple of scenarios in which 12 hours might make a difference: Your hCG level just happens to cross over your test's sensitivity threshold during that 12-hour time period.

A pregnancy test can read positive as early as 10-14 days after conception, which is typically around the time of your expected period. The key factor is the presence and level of the hormone human chorionic gonadotropin (hCG) in your body, which starts to increase after a fertilized egg implants in the uterus.

HCG is normally only present in your body if you are pregnant. Any positive line, no matter how faint, means your result is pregnant. Levels of hCG in your body will increase over the course of your pregnancy. If you test early, your hCG levels may be still be low and you'll see a faint positive line.

But even a faint positive line has color, and this distinguishes it from an evaporation line, which is colorless. Any coloration in a positive line indicates pregnancy. A mark on a pregnancy test may be an evaporation line if: More than 10 minutes have passed since taking the test.

What color are EVAP lines on pregnancy tests? ›

While a true positive pregnancy test will contain some color, an evap line will be colorless. "Evap lines may be fainter, and in a different spot than where you would expect the pregnancy test [results]," she explains.

The hook effect incorrectly gives you a negative result on a pregnancy test. This can happen during early pregnancy or in rare cases — even into the third trimester, when it's pretty clear you're preggers. During pregnancy your body makes a hormone called human chorionic gonadotrophin (hCG).

The main benefit is — you guessed it — they're cheaper! But they work just as well. The results of less expensive pregnancy tests will still be up to 99 percent accurate when you use them according to the manufacturer's instructions.

A false negative pregnancy test can happen because you conceived later than you think, you didn't take the test correctly, your urine was diluted, or even because you're pregnant with multiples.

When you can do a pregnancy test. You can carry out most pregnancy tests from the first day of a missed period. If you don't know when your next period is due, do the test at least 21 days after you last had unprotected sex. Some very sensitive pregnancy tests can be used even before you miss a period.

After implantation, production of hCG starts from cells in the developing placenta (tissue that will feed the fetus). Trace levels of hCG can be detected as early as eight days after ovulation. That means you could get positive results several days before you expect your period to start.

You might get a false-negative if you: Take the test too early. The earlier you take a home pregnancy test, the harder it is for the test to find HCG . For the most accurate results, take a home pregnancy test after the first day of a missed period.

How soon can you take a pregnancy test? Some tests are very sensitive and can show if you are pregnant before your period is due. However, it is best to wait until at least the first day of a missed period to take any test. For a more accurate result, take the test a week after your missed period.
