Non-pregnant females: < 3 mIU/mL
Males: < 2 mIU/mL
Healthy non-pregnant peri-menopausal and post-menopausal females may
have HCG values up to 8 mIU/mL. Heterophile antibodies present in the
serum of some patients may cause a false positive result in this
assay.
Comments:
This assay may be significantly impacted by high-dose biotin (>5 mg
dose) taken within previous 12 hours. High concentrations of biotin
may lead to falsely decreased results. These concentrations may be
found in patients taking over-the-counter supplements with biotin
content much higher than nutritional requirements for biotin.
Specimens should not be collected until at least 12 hours after the
last dose.
This assay recognizes the intact HCG "holo-hormone" produced in pregnancy but may not recognize other forms of HCG (e.g., "nicked HCG") produced in other conditions such as tumors of the germs cells, ovaries, bladder, pancreas, stomach, lungs, and liver.
This test is also performed in the Iowa River Landing (IRL) clinical laboratory (for specimens drawn at that site).
