What Are the Accuracy Levels of Rexall Pregnancy Tests?

Rexall Pregnancy Tests are an easily accessible and affordable way to test for pregnancy at home. This type of testing is used by a majority of women when they suspect they may be pregnant.

Test Reliability

The reliability of the Rexall Pregnancy Test is high, with false positives being extremely rare. The accuracy of the test is dependent on the user following the instructions that come with with the test, and understanding the limitations of the test. More reliable results can be obtained by taking a second test 7-10 days after the first to confirm the accuracy of the test results.

Test Timing

Rexall Pregnancy Tests are available over-the-counter and online and should be taken as early as 10 days after a missed period. The accuracy of the test can be improved by understanding the different factors that can affect the test results, such as time of day, the amount of water consumed and the concentration of the sample used.

Factors That Impact Accuracy

  • Time of Day: It is best to test for pregnancy in the morning as the levels of hCG (human chorionic gonadotropin) tend to be at their highest.
  • Amount of Water Consumed: Too much water prior to the test can dilute the sample, making the results inaccurate.
  • Concentration of Sample: If the sample is too thin or diluted, the accuracy of the test results can be affected.


In conclusion, Rexall Pregnancy Tests are highly reliable and accurate when used according to the instructions provided. By following the instructions and understanding the factors that can impact the test results, users can confidently utilize this type of testing to determine if they are pregnant.

What to Know about the Accuracy of Rexall Pregnancy Tests

Rexall Pregnancy Tests are a fast, convenient way to determine if you’re pregnant. But how accurate are they?

How Accurate Is a Rexall Pregnancy Test?

Rexall Pregnancy Tests are 99 percent accurate when used according to package instructions and as early as the day of your missed period. The test measures the human chorionic gonadotropin (hCG) hormone level in your urine to determine if you are pregnant or not. Early in pregnancy, hCG levels rise quickly and double every two or three days—which is why it’s best to wait until the day of your expected period to get the most accurate results.

Other Factors That Affect the Accuracy of Rexall Pregnancy Tests

There are a few things that can affect the accuracy of Rexall Pregnancy Tests, including:

  • Urine concentration: Urine that’s more concentrated may give a false positive result. Make sure to read the test instructions and use first morning urine for the most accurate results.
  • Expiration date: Rexall Pregnancy Tests expire, so make sure to check the expiration date on the package before you use it.
  • Ectopic pregnancy: Ectopic pregnancy occurs when the embryo is implanted outside of the uterus, which can give a false negative result.
  • Testing too early: If you take the test too early in your pregnancy, it may give a false negative result. It’s best to wait until the day of your missed period to get the most accurate result.

Interpreting the Results

With Rexall Pregnancy Tests, you have two lines on the indicator window to look for — a control line (indicating the test worked) and a test line (indicating if you’re pregnant).

  • A positive result occurs when two distinct lines appear in the indicator window — any shade of color is considered a positive result.
  • A negative result occurs when either one line appears in the indicator window or no line appears. If a faint line appears, it’s best to wait a few days and retest to confirm the result.
  • If a test shows an invalid result, it’s possible you have done something wrong. Otherwise, it may be a defective test. In this case, it’s best to buy a new test.


Rexall Pregnancy Tests can be a fast and convenient way to find out if you’re pregnant—as long as you read the package instructions, follow directions, and test on the day of your expected period. With the proper use, Rexall Pregnancy Tests are 99 percent accurate. Other factors that can affect the accuracy include the concentration of your urine, the expiration date, ectopic pregnancy, and testing too early. Finally, look for two distinct lines in the indicator window—a control line and a test line—to determine the results.
