Test Principle

Highly purified human albumin is bound to microwells. The reaction is based on a competitive ELISA method with these steps: Calibrators, controls and urine samples are incubated together with anti-albumin-peroxidase conjugate in the wells. Albumin, if present, will compete with coated albumin for binding of the anti-albumin-conjugate. Washing of the microwells removes unspecific components. Bound enzyme conjugate will hydrolyze the enzyme substrate TMB. The addition of acid stops the reaction forming a yellow end-product. The intensity of this yellow colour is measured photometrically at 450 nm. The amount of colour is inversely proportional to the concentration of albumin present in the original sample.
