Significance: AFP should be used in conjunction with other clinical and biochemical markers for the diagnosis and monitoring of testicular cancer. AFP may be used in conjunction with ultrasound in high risk patients to aid in the diagnosis and monitoring of hepatocellular carcinoma. AFP is not recommended for cancer screening in a general population. AFP may be elevated in other conditions including: hepatitis, drug induced hepatic damage, cirrhosis, gastrointestinal cancers, hereditary tyrosinemias and normal pregnancy. This assay is not intended for the prediction of neural tube defects in pregnant women. The serum AFP concentration alone does not provide absolute evidence of the presence of malignant disease.
