α-Fetoprotein (AFP), Tumor Marker (Serial Monitor)
Also known as: Alpha-Fetoprotein (AFP), Serum, Tumor Marker (Serial Monitor)
Use
The α-Fetoprotein (AFP), Tumor Marker (Serial Monitor) test is primarily used in the long-term serial monitoring of Alfa-Fetoprotein levels in patients who may be undergoing treatment or monitoring for certain types of cancers, particularly liver cancer and some germ cell tumors. Serial monitoring allows for the tracking of AFP levels over time to observe changes and assess the effectiveness of treatment or check for recurrence.

Limitations
Results obtained with different assay methods or kits cannot be used interchangeably. This test should not be interpreted as absolute evidence of the presence or absence of malignant disease. It is not interpretable in pregnant females due to naturally occurring high levels of AFP. Interference may occur with biotin-rich supplements.
