This test is not intended for aiding in the diagnosis of cancer or for monitoring the treatment of cancer patients.
The concentration of HCG rises rapidly during the first weeks of pregnancy, approximately doubling every two days. Low level HCG values >25 mIU/mL may be indicative of early pregnancy, but these results should always be evaluated in the context of the clinical situation: date of last menstrual period, pelvic examination and other clinical findings. When borderline results are encountered, patient should be redrawn 48 hours later.
