Collection & Request Instructions:

AFP is useful in monitoring some testicular germ cell tumours and primary hepatocellular carcinoma. After treatment, e.g. orchidectomy, levels fall with a half-life of approximately 45 days. Values > 500 ug/L are virtually diagnostic of malignancy. However, 50% of all malignancies have values < 500 ug/L. AFP can also be raised in a variety of non-malignant liver disorders, where levels are usually < 100 ug/L.

Transport Instructions between Sites and/or Laboratories:

Room Temperature

Additional Notes:

Reference Range: < 9 ug/L
