Content: Detecting hCG in the urine of someone 6 months pregnant (when there's plenty of hCG) versus 6 days past ovulation (when there's a very small amount of hCG) are two very different tasks. The ability of a test to pick up small amounts of hCG in your urine depends on the sensitivity of the test. It's not always easy to tell which tests are the most sensitive. New products come out frequently, and manufacturers can make improvements at any time. But some package inserts provide information about a test's sensitivity – that is, they report the lowest concentration of hCG in milli-International Units per milliliter (mIU/ml) of urine that the test can detect. For example, a pregnancy test that claims to be able to detect hCG at 20 mIU/ml should be more sensitive than one that claims to detect it at 50 mIU/ml. advertisement | page continues below
How do I use a home pregnancy test? For best results when using a home pregnancy test: Make sure the test is current. Check the expiration date on the package, especially if you've had it for a while.
