When to Take a Premom Pregnancy Test for Accurate Results

When Can I Take a Premom Pregnancy Test for Accurate Results?

Premom pregnancy tests are popular over-the-counter options for those trying to conceive. But knowing the best time to take a Premom test can give you the most accurate results.

In this article, we'll look at how Premom pregnancy tests work, factors that impact accuracy, and when you can expect reliable results whether it's early in your cycle or after a missed period.

How Do Premom Pregnancy Tests Work?

Like other home pregnancy tests, Premom tests detect the presence of human chorionic gonadotropin (hCG) in urine. hCG is a hormone produced by the placenta shortly after an embryo implants in the uterus.

Premom tests use strips with absorbent pads that take up urine from a collected sample. The urine travels up the strip to the result window. If hCG is detected, it will bind to antibodies on the test strip and highlight the test line.

A control line will also appear to confirm the test is working properly. Results are complete within 3-5 minutes.

Why Testing Timing Matters

Trying to test too early when hCG levels are still low can lead to false negative results. But how soon can you take a Premom test and get an accurate positive?

The time it takes for hCG to rise high enough to get picked up varies between women. Factors like the sensitivity of the test, cycle regularity, date of ovulation, and other individual variables impact the earliest detectable day.

hCG Rises Progressively

After implantation, hCG levels double every 48-72 hours during early pregnancy. It takes time for the hormone concentration to build up enough to exceed the minimum threshold of a test.

Sensitivity Varies Between Tests

Premom tests can detect hCG levels as low as 25 mIU/mL. More sensitive tests like First Response can detect lower levels down to 6.3 mIU/mL.

Later Ovulation Delays Implantation

If ovulation happened later in your cycle, implantation and subsequent hCG rise will also occur later. This means you may need to wait longer before testing.

When to Take a Premom Pregnancy Test

So when can you take a Premom test and expect accurate results? Here are some general guidelines:

Before Your Missed Period

It's possible to get a positive Premom test around 4-5 days before your expected period. However, false negatives are common at this stage since hCG may still be low.

Day of Your Expected Period

Testing on the day your period is due yields accurate positive results for around 70% of women. Testing too early accounts for most negative results.

1 Week After Your Missed Period

By one week after a missed period, Premom tests approach 99% accuracy. Enough time has passed for rising hCG to be detected in almost all pregnant women.

2+ Weeks After Your Missed Period

Waiting more than 2 weeks after your missed period essentially guarantees accurate test results, whether positive or negative. At this point hCG is readily measurable if pregnant.

Ovulation Testing Can Guide Timing

Using ovulation predictor kits or tracking ovulation symptoms can help pinpoint when implantation could occur. This allows you to time pregnancy testing more precisely.

Tips for Accurate Premom Pregnancy Test Results

Besides timing, there are other tips to get the most accurate Premom test results:

Follow All Test Directions

Read the test instructions fully and follow them closely for proper testing. This includes only collecting urine mid-stream and completing all test steps.

Use First Morning Urine

Taking the test with your first morning urine contains the most concentrated hCG levels, boosting accuracy.

Don't Drink Too Much Fluid Beforehand

Avoid excess fluid intake in the 2-3 hours before testing as this can dilute hCG in the urine sample.

Don't Take Apart the Test

Disassembling the test after use invalidates the results. The results are only valid within the testing time frame.

Consider Testing Multiple Days

Take Premom tests over a few consecutive days if you get unexpected negatives but still think you may be pregnant.

Interpreting Premom Pregnancy Test Results

Positive Results

If two colored lines appear within the result window within 5 minutes, one in the test area and one in the control area, the Premom test is positive.

This means hCG was detected and you are likely pregnant. However, false positives are possible in rare cases.

Negative Results

Only one line appearing in the control window, with no line in the test window, signals a negative result. This indicates urine hCG wasn't high enough to trigger a positive test.

If taken too early, negative tests should be retaken a few days to a week later to confirm results.

Invalid Results

If no lines or only a test line shows up, the Premom test is invalid. Similarly, if lines show up after the 5-minute reading window, the test should be disregarded.

Invalid tests should be retaken with a new test kit.

The Takeaway

To maximize accuracy avoid taking Premom tests too early, follow all test directions, use concentrated urine, and consider testing over multiple days. While testing 4-5 days before a missed period is sometimes possible, it often yields false negatives.

Waiting until at least the day after a missed period allows enough time for hCG to rise to detectable levels and provides accurate Premom test results. Being aware of when you can take a Premom test for optimal results takes the guesswork out of early pregnancy testing.
