First Response Pregnancy Test
From LoveToKnow Pregnancy
The First Response Pregnancy Test is one of the most popular home pregnancy tests on the market.
First Response Pregnancy Test Instructions
To take a First Response Pregnancy Test, all you have to do is:
- Remove the test stick from the wrapper and remove the cap.
- Hold the test stick, with the absorbent tip end pointed down under your urine stream for five seconds.
- Replace the cap and lay the test down flat, with the results window side of the stick up.
- Wait up to three minutes for the results to show in the results window.
How to Read First Response Test Results
The test ready after two minutes. If you see two lines, you are pregnant. If you see only one line, you're not pregnant, at least not yet. Try testing again in a few days since you may just tested too early.
When to Use First Response
The First Response Pregnancy Test can be taken as early as four days before your next expected period with markedly accurate results. The level of accuracy is dependent on when you take the test:
- If the pregnancy test is taken four days prior to your next period, there is a 69% chance an accurate response.
- If you wait until three days prior to your next period, the accuracy increases to 83%.
- If the First Response Pregnancy Test is taken one to two days prior to your next expected period, the accuracy increases to 93%.
- Waiting until after you have missed the first day of your period increases the accuracy of the pregnancy test to 99%.
How First Response Works
The First Response Pregnancy Test is designed to lest the level of human chorionic gonadotropin (hCG) in your urine. This particular hormone is only present in women who are pregnant or taking specific medications. Normally, it takes at least until four days before your next period before enough hCG has built up in your body to activate a positive result when taking a pregnancy test. In some women, it may take longer before the hCG levels are adequate to get a positive test result.
While you can take the First Response Pregnancy Test any time of the day, you can help ensure you are testing with the highest level of hCG in your urine by waiting to use your first urine of the day.
How Long Test Results Are Accurate
Ideally, you will read the First Response Pregnancy Test results as soon as possible after the required three minute processing wait. If the test results are positive, the results should still show positive in the result window for at least 48 hours, but if the results are negative, the test result window may show no line as soon as ten minutes after the test is taken.
Inaccurate Test Results
While the First Response Pregnancy Test is extremely accurate, many factors may lead to an inaccurate pregnancy test result. Among these factors are:
- Medications that may contain hCG
- Miscalculating your due date
- Failure to adequately saturate the test stick tip
- Over saturating the test stick tip
- Failure to lay the test flat while waiting for the test results to process
If you think your pregnancy test result is wrong, wait three days and retake the test, or visit with your health care professional.

Comments
Nereyda,
false positives are rare, but one reason could be if you are testing early. You may have had enough detectable HCG in your first morning urine, but not enough in the second. Again, this would usually only happen if you are testing too early, usually before your period is due. You'll need to follow up with your doctor or take another test as a tie breaker.

if both lines showed up, you are pregnant even if it's faint. If you are doubtful of the results, you should take another test or contact your doctor for a Blood-based Pregnancy Test.
