Elevated AFP is associated with certain tumors. AFP levels are also used to monitor suspected hepatic dysfunction, newborn tyrosinemia, and other diseases.

Tumor marker assays cannot be used interchangeably; this test is performed using the Siemens Atellica AFP Immunoassay effective 7/13/21. Heterophilic antibodies may cause interference. Refer to Memo #172
