A method which provides a quick simple means of assessing plasma or serum specimen integrity with respect to bile pigments is described. Application of the method simultaneously screens serum or plasma specimens for elevated levels of bilirubin (BR) and biliverdin (BV) by providing a measure of these interferents known as the bilirubin-biliverdin index or BBI. The method involves determination of concentrations of BV in a plasma or serum specimen, based on the results of spectrophotometric determinations of absorbance or reflectance measurements conducted in the near infrared region, and thereby a determination of the BBI in respect of the specimen and on the basis of the resulting BBI a decision as to acceptance or rejection of the sample. |
