clear pregnancy test

Most home pregnancy tests use urine and detect the pregnancy hormone hCG in the urine.

Results can appear as fast as about 1 minute and typically within around 3 minutes. Some tests advertise early detection up to about 5–6 days before a missed period.

Tests display results as colored indicator lines, plus/minus symbols, or clear digital words. Some also use a color-changing absorbent tip to confirm proper sampling.

Many tests state over 99% accuracy from the day you expect your period. Early-detection performance varies: examples show about 56% detectable 5 days before a missed period and about 77–78% detectable 6 days early. Listed test sensitivities include 10 mIU/ml and 25 mIU/ml.

A pregnant result can appear for some tests in about 1 minute, but you should wait the full instructed time—typically up to about 3 minutes—to confirm a not-pregnant result.

The listed detection limits include sensitivities of 25 mIU/ml and 10 mIU/ml for different tests.
