Collect specimen in a clean, dry container – specimens collected at any time of day may be used; however, the first morning urine generally contains the highest concentration of hormone.

Urine may be stored at 2-8°C for 72 hours prior to assay. If samples are refrigerated, they must be equilibrated to room temperature before testing. Urine samples exhibiting visible precipitates should be filtered, centrifuged or allowed to settle, prior to testing.

Normal, non-pregnant:  Negative

NOTES:
Negative test results in patients suspected to be pregnant should be retested with a sample obtained 48-72 hours later, or by performing a quantitative assay.
When testing with a urine specimen, the first morning specimen would contain the highest hCG concentration.
Borderline samples (those showing a very faint line in the test region) that later test negative may be attributed to falling hCG levels following a spontaneous or induced abortion.

Human chorionic gonadotropin (hCG) is a glycoprotein hormone secreted by the developing placenta shortly after fertilization. In normal pregnancy, hCG can be detected in serum and urine as early as 7 days following conception  The concentration of hCG continues to rise rapidly, frequently exceeding 100 mIU/mL by the first missed period and peaking in the 100 - 200 mIU/mL range by 10-12 weeks into pregnancy.

Rapid urine HCG tests can detects the presence of hCG in a qualitative format sensitive to 20 mIU/mL in urine and 10 mIU/mL in serum.
