2 days before expected period= 90% accurate

1 day before expected period =95% accurate

the day of expected period =99% accurate

Answer 2

A serum hCG can usually confirm pregnancy about 10 days past conception, a urine hCH takes a few days longer, at about 14 days past conception. Remember every woman and every pregnancy is different so you may test positive a couple days sooner or a few days later and everything is still completely normal.

All pregnancy tests measure the amount of human chorionic gonadotropin (hCG), the pregnancy hormone, in your body. Home pregnancy tests detect the presence of hCG in your urine and a serum tests for hCG in the blood. The more sensitive tests may be able to detect low levels of hCG as early as four days before your period is due, or seven days after conception.

The sensitivity of a pregnancy test is described on the packaging as mIU/ml (milli-International Unit per millilitre). Pregnancy tests range in sensitivity from 10mIU/ml to 40 mlU/ml. The lower the number, the more sensitive the test, and the earlier it can detect pregnancy.

If you test too early in pregnancy, even with a sensitive test, the amount of hCG in your urine may not be high enough to detect. Most home pregnancy tests will give accurate results if you test at the time your period would normally be due, about two weeks after you ovulate.

To be accurate a test should be taken after the first missed period. Any sooner and it is likely to give a false reading.
