Patients who have received monoclonal mouse antibodies may have abnormal results. For any patient taking a high dose of biotin, the specimen should be drawn at least eight hours after the last dose.

Pediatric range is based on full term neonates, values for premature infants may be higher. Ranges adopted from: SJ Soldin, et al. "Pediatric Reference Ranges." Third ed. AACC press (1999). This test was performed using the Siemens (DPC) chemiluminescent method. Values obtained from different assay methods cannot be used inter- changeably. AFP levels, regardless of value, should not be interpreted as absolute evidence of the presence or absence of disease.

Clinical Significance

Elevation of serum AFP above values found in healthy individuals occurs in several malignant diseases, most notably nonseminomatous testicular cancer and primary hepatocellular carcinoma. AFP is not recommended as a screening procedure to detect cancer in the general population.
