HCG, Qual Urine

False negative results may occur when HCG levels are below the sensitivity level of the test. (20 mIU/mL)
When pregnancy is still suspected, retest in 48 hours.
Ectopic pregnancy may produce very low levels of HCG, if suspected, further testing using a quantitative method may be desirable.

A number of conditions other than pregnancy, including trophoblastic disease and certain non-trophoblastic neoplasms including testicular tumors, prostate cancer, breast cancer, and lung cancer, cause elevated levels of hCG. In addition, low levels of hCG can naturally occur from the onset of perimenopause.

This test provides a presumptive diagnosis for pregnancy. A confirmed pregnancy diagnosis should only be made after all clinical and laboratory findings have been evaluated.
