The use of the glutaraldehyde coagulation test for detection of hypogammaglobulinaemia in neonatal foals

Abstract
The effectiveness of the glutaraldehyde coagulation test (GCT) in detecting failure to acquire colostral immunoglobulin in neonatal foals was investigated. This was acheived by comparing and correlating results from the GCT with those obtained by single radial immunodiffusion (SRID) of equine IgG. The GCT was found to be a practical inexpensive, semiquantitative test with a high specificity and sensitivity at critical IgG levels.
