How Home Pregnancy Tests Work
Timing, accuracy, false results, and next steps after a positive or negative read.
4 min read · Reference: FDA home pregnancy test information
Home tests detect human chorionic gonadotropin (hCG) in urine. Most become reliable from the first day of a missed period; early-result kits may work a few days sooner with variable accuracy.
Dilute urine from excessive fluid intake can cause false negatives. Evaporation lines may be mistaken for positives—read within the package time window.
A negative test with ongoing symptoms or irregular bleeding should be repeated in 48–72 hours or confirmed with a clinician. Positive results warrant prenatal or options counseling based on personal goals.
Ectopic pregnancy and miscarriage can produce confusing patterns; seek urgent care for severe one-sided pain or heavy bleeding.
