[Evaluation of the Unicel DXC 600 (Beckman Coulter) and comparison with Integra 800 (Roche Diagnostics)]

The Unicel DXC 600 is an automated analytical system from Beckman Coulter for measuring usual biochemistry parameters (electrolytes, substrates and enzymatic activities), therapeutic drugs, drugs of abuse and specific proteins. According to the "Société française de biologie clinique (SFBC)" validation protocol, we tested the following parameters: electrolytes (sodium, potassium, chloride, total CO2), substrates (uric acid, calcium, phosphate, glucose, creatinine, urea, cholesterol, HDL cholesterol, bilirubin, iron, triglycerides), enzymes (ALAT, ASAT, amylase, CK, GGT, LDH, lipase, ALP), total proteins and specific proteins (albumin, CRP, haptoglobin). The results confirm the excellent analytical performances regarding imprecision. The comparison study shows differences between values obtained with Unicel DXC 600 and Integra 800 (Roche diagnostics), leading to the use of correcting factors for some parameters.
