Abstract

We are not surprised that three methods, each determining the saturation of serum albumin with bilirubin by the addition of excess bilirubin, should correlate with each other. We have shown a similar correlation of bilirubin binding capacity by peroxidase and Sephadex methods in a previous article.1 We would be surprised if the addition of 2-( 4'-hydroxybenzene)azobenzoic acid (HABA) or another dye possibly bound to nonbilirubin sites on albumin would give a better correlation than the addition of bilirubin itself in different methods.
