Limitations
While pregnancy is the most likely reason for the presence of hCG in serum and urine, other conditions may be associated with detectable hCG, i.e., ectopic pregnancy, molar pregnancy or patients with trophoblastic and nontrophoblastic disease. Early pregnancy associated with low levels of hCG may not be detected with this kit. If pregnancy is suspected, consider ordering a serum quantitative hCG or re-collect in 48 hours. hCG may remain detectable a few days to several weeks after delivery, abortion, natural termination or hCG injections.
This test may not be used as a tumor marker assay. Serum samples may be sent to Mayo Medical Laboratories, see Beta HCG, Tumor Marker, serum (BCGC) for details
This test will detect urine concentrations of Beta-hCG as low as 20 mIU/mL
