To detect and confirm pregnancy

To aid in the diagnosis of hydatidiform mole or human chorionic gonadotropin (hCG)–secreting tumors, threatened abortion, or dead fetus

If appropriate, explain to the patient that the urine hCG test determines whether she’s pregnant or determines the status of her pregnancy.

Tell the patient that she need not restrict food but should restrict fluids for 8 hours before the test.

Inform the patient that the test requires a first-voided morning specimen or urine collection over a 24-hour period, depending on whether the test is qualitative or quantitative.
