False positive ovulation tests are relatively uncommon, but can occur for a variety of reasons. The most common cause of a false positive is ovulation itself. If you test too early in your cycle, or if you have a shorter than average cycle, it's possible to get a positive result when you actually haven't ovulated yet. Other causes of false positives can include very low levels of the hormone LH, which is what the test measures, or medications like Clomid that stimulate ovulation. In rare cases, a small tumor on the pituitary gland can cause elevated LH levels and lead to a false positive test result.
If you get a positive ovulation test result, there's no need to panic. Just remember that it's possible to get a false positive, and wait a few days to retest. If the second test is positive, then you can be sure you're ovulating.
Frequently Asked Questions
Can ovulation tests give false positive results?
Yes, ovulation tests can give false positive results. This means that you may not be ovulating, even though the ovulation prediction kit tells you that ovulation is around the corner. Falsepositive ovulation testing results are one where you get a positive result when you are not about to ovulate.
Why do ovulation test kits expire?
The life of the ovulation test kit's detecting particles is about three days. This is why the LH test will expire about one day after being activated, and the HCG test will expire in about two to three days.
Can you get a false positive on an expired pregnancy test?
Yes, a false-positive on an expired pregnancy test is possible. Expiration dates on tests taken at home are not always accurate and tests can be affected by heat or moisture.
Why do I keep getting positive ovulation test?
A positive ovulation test means that there is currently a LH surge and this can mean that you are more likely to conceive. However, it is only indicative and does not always mean that you are actually pregnant - so it is best to just relax and wait for a missed period.
Are multiple positive ovulation tests in a row considered a false positive?
Multiple positive ovulation tests in a row are not considered a false positive result. It indicates that your LH surge is strong and lasts longer than average. You should ovulate within 24 to 36 hours of the first positive result that you received.
