Test Usage

Immunoassay intended for the qualitative detection of human Chorionic Gonadotropin (hCG) in urine for the early detection of pregnancy.

Test Methodology

Enzyme Immunoassay

Additional Information

Test results must always be evaluated with other data available to the physician. 
A normal pregnancy cannot be distinguished from an ectopic pregnancy based on hCG levels alone. 
Very low levels of hCG are present in serum and in urine shortly after implantation. Positive test results from very early pregnancy may later prove negative due to natural termination of pregnancy.
Patients with trophoblastic and nontrophoblastic disease may have elevated hCG levels, therefore, the possibility of hCG secreting neoplasms should be eliminated prior to the diagnosis of pregnancy.
