A competitive immunoenzymometric assay for albumin in urine

I describe a competitive immunoenzymometric assay for urinary albumin, with use of an immobilized albumin-thyroglobulin conjugate and an affinity-purified antibody. The assay is rapid, easy to perform, has a range of 0.5 to 78 mg/L, and is ideally suited for screening purposes. Higher concentrations may be assayed by further dilution of the urine sample. Results compare favorably with those of a commercially available radioimmunoassay kit.
