Interpretive Data:

The Abbott Alinity I Immunoassay System (Chemiluminescense Technology) is used to perform this assay.  Reference range is adapted from Abbott method literature.  Results obtained by other manufacturers’ assays may be different and should not be interpreted interchangeably.

 

The following information is provided to assist in the interpretation of serum alpha-fetoprotein (AFP) results obtained by AbbottAlinity immunoassay method. The AFP immunoassay is not a screening test for cancer. Do not interpret serum AFP levels as absolute evidence of the presence or absence of malignant disease. AFP testing should be done in conjunction with other clinical and diagnostic information. Elevated AFP values may be found in patients with confirmed non-malignant conditions. Low AFP levels do not necessarily indicate absence of disease.
