Clinical Info:

In normal pregnancy, hCG can be detected in both serum and urine as early as 7 to 10 days after conception. hCG levels continue to rise very rapidly, frequently exceeding 100 mIU/mL by the first missed menstrual period, and peaking in the 100,000-200,000 mIU/mL range about 10-12 weeks into pregnancy.
Human chorionic gonadotropin (hCG) is produced in the placenta during pregnancy. In nonpregnant women, it can also be produced by tumors of the trophoblast, germ cell tumors with trophoblastic components, and some nontrophoblastic tumors.

Additional Information:

Immunoassay for the detection of human chorionic gonadotropin (hCG) in human serum.This assay is intended for the early detection and monitoring of pregnancy.
Healthy, non-pregnant individuals typically have low (< 10 mIU/mL [IU/L]) to undetectable hCG levels; however, hCG can rise to detectable levels in peri- and post-menopausal women. hCG results between 5 mIU/mL and 25 mIU/mL may be indicative of early pregnancy but should be interpreted in light of the total clinical presentation of the patient.

Sample Collection:

Test Limitations:

This test is designed for the quantitative detection of human chorionic gonadotropin (hCG) in human serum. If you would like to get a qualitative value of hCG please order the following test: SAL# 698. For urine hCG qualitative testing please use SAL# 699.
False negative results may occur when the levels of hCG are below the sensitivity level of the test. When pregnancy is still suspected after an initial negative result, a second specimen should be collected 48 hours later and tested.
This test provides a presumptive diagnosis for pregnancy. A confirmed pregnancy diagnosis should only be made by a physician after all clinical and laboratory findings have been evaluated.
