: What This Test Measures
: This test detects human chorionic gonadotropin (hCG), a hormone produced by the placenta after implantation. The term "function status" refers to interpreting whether the hormone is present in a way that indicates an active pregnancy state.
: How the Test Is Done
: Pregnancy testing is usually performed on a urine or blood sample. Urine tests are common in clinics and at home, while blood tests can detect hCG earlier and allow more precise measurement. Your healthcare provider will choose the sample type and method.
: What Results Mean
: A positive result generally suggests pregnancy, and a negative result generally suggests it is not detected at the time of testing. Timing matters: testing very early, dilute urine, or certain medications and medical conditions can affect results. Your provider interprets results alongside your history and symptoms.
: Why Your Provider May Order It
: Providers order pregnancy testing to evaluate missed periods, confirm suspected pregnancy, guide treatment decisions, or check pregnancy status before procedures or medications. It may also be used to monitor early pregnancy when serial measurements are needed.
