Reference Range:1 year and up <8.1 ug/L.
Reference values for adult non-pregnant female only, fetal production of AFP elevates values in pregnant women. Ranges for newborns are not available, but concentrations over 100,000 ug/L have been reported in normal newborns. Values rapidly decline to <100 ug/L by 5 months and reach adult levels by 1 year. The ADVIA Centaur AFP method is used. Results obtained with different assay methods or kits cannot be used interchangeably.
Use:Aids in the differential diagnosis and therapeutic monitoring of germinal neoplasms of the testis, ovary, retroperitoneum, mediastinum, and heptocellular carcinoma. Seminomas do not produce AFP.
