[Determination of factor X Ag by laser immunonephelemetry].
A method of dosage of X Ag factor by laser immunonephelemetry is proposed. This technique, carried out with a rabbit antiserum in the presence of PEG and EDTA, presents the advantage to be sensitive, reproducible and mostly faster than the other immunological methods, such as Electroimmunodiffusion (EID) and Enzyme Linked Immuno-Sorbent Assay (ELISA). It constitutes a simple tool, applicable in the demonstration of an enzyme dysfunction or liver pathology. Finally, it could bring a supplement of information in monitoring antivitamin K therapy.
