Comparison of the hemagglutination inhibition assay kit for erythropoietin
(ESF) with the fetal mouse liver cell bioassay in vitro
G de Klerk, RJ Vet, PC Rosengarten and R Goudsmit
The commercially available hemagglutination inhibition (HAI) assay kit for
erythropoietin (ESF) was compared with the fetal mouse liver cell (FMLC)
bioassay. No correlation was obtained ESF levels determined by both methods
in a variety of pathologic sera. The HAI kit showed a great batch
variability. Significant immunoreactivity was found in those fractions of a
normal human serum and a human urinary ESF preparation that were not active
in the FMLC bioassay. A very poor recovery of immunoreactivity was found
when the international reference preparation for erythropoietin (second
IRPE) was added to a normal human serum.
