Can a lab urine pregnancy test be wrong?

Yes, a lab urine pregnancy test can be wrong. While lab urine pregnancy tests are generally very accurate, there are some instances where they may give false positive or false negative results.

False positives can occur when certain substances in the urine, such as certain medications or hormones, interfere with the test. For example, some fertility medications can cause a false positive pregnancy test result.

False negatives can occur when the levels of hCG in the urine are too low to be detected by the test. This can happen early in pregnancy, when the hCG levels are still rising, or in cases where the pregnancy is not viable.

If you receive a positive pregnancy test result, it is important to confirm the results with a blood pregnancy test. A blood pregnancy test is more sensitive and can detect lower levels of hCG.

If you receive a negative pregnancy test result but you believe you may be pregnant, it is important to see your doctor to rule out pregnancy and to determine the cause of your symptoms.
