When Is This Test Done?

Your healthcare provider may recommend this test if you suspect you might be pregnant, especially before a missed menstrual period. It can also be used to monitor hCG levels in cases of ectopic pregnancy, molar pregnancy, or other conditions requiring hormone level tracking.

What Does a Positive Result Mean?

A positive result indicates the presence of hCG, which is typically associated with pregnancy. However, hCG can also be present in non-pregnant individuals due to certain medical conditions, so further evaluation may be needed.

What Does a Negative Result Mean?

A negative result means no detectable hCG was found in your urine. This can mean you are not pregnant, but it does not rule out pregnancy if tested too early. If you suspect pregnancy, retesting after a few days may be advised.

How Is This Test Performed?

This test involves collecting a urine sample, typically in the morning when hCG levels are usually highest. The sample is then analyzed in a lab using immunoassay methods to measure hCG concentration.

Frequently asked questions

Why might my healthcare provider order this test?
Your healthcare provider may order this test to confirm pregnancy, especially if you have missed your period or suspect you might be pregnant. It can also be used in cases of suspected ectopic pregnancy, unexplained vaginal bleeding, or to monitor hCG levels in certain medical conditions.
What are the possible reasons for a false-positive or false-negative result?
False positives can occur due to certain medications, medical conditions, or laboratory errors. False negatives might happen if the test is taken too early in pregnancy or if the sample was not collected correctly. Always discuss results with your healthcare provider for accurate interpretation.
How soon after conception can this test detect pregnancy?
This test can often detect pregnancy within 6 to 11 days after conception, depending on the sensitivity of the test kit used. Early results may be less accurate, so retesting may be recommended if needed.
