Hemoglobin is measured photometrically at 525 nm using the sample from the white cell analysis. Clean diluent is introduced into the cuvette during each operating cycle and is used as a blank in the calculation of the HGB. Why are you asking? High backgrounds or erratic HGB results...? I'm an expert on the UniCel DxH800/600/690T/900 and the UniCel DxH SMS. The most difficult aspect to the HGB subsystem is getting everything aligned, (Lamp, HGB cuvette and the photometer).
