Improper handling of the control material by Photodegradation generally results in a greater Laboratory A resulted in loss of bilirubin due to loss of bilirubin at higher concentration and also photodegradation contributes to random error. Laboratory B obtained higher results because its caused by a sample with a very high concentration precision was poorer of analyte preceding a normal sample.
