hCG is secreted by the placenta shortly after fertilization and implantation.
UPT is a qualitative test that detects hCG in urine.
Clinical uses include:
Confirming early pregnancy.
Supporting evaluation of amenorrhea or suspected pregnancy.
Used in emergency and outpatient settings for quick results.
Often performed as a point‑of‑care test (POCT) using dipsticks or kits.
May be followed by serum hCG tests and ultrasound for confirmation.
