Enzymatic Homocysteine Test Kit (Olympus)

Beckman AU packaging, a convenient dual vial liquid stable assay ideal for analysers which require two part reagent systems. The Diazyme Homocysteine 2 Reagent Enzymatic Assay is intended for the in vitro quantitative determination of total L-homocysteine in serum or plasma. The assay can assist in diagnosis and treatment of patients suspected of having hyperhomocysteinemia and homocystinuria. The assay provides a fast, accurate cost effective alternative to cumbersome and expensive immunochemical methods. The assay is offered with convenient instrument specific packaging options which eliminate reagent transfer for Beckman AU (400/600/640/680) analysers. Accurate and reliable, the assay features excellent correlation with HPLC and immunochemical methods with a linear range of 3-50 umol/L and intra and inter %CV values of < 7.5%. The assay has no significant interference from lipemic and hemolytic substances and eliminates the "carry-over" interference with iron or lipase reagents that can occur with other methods. More significantly, the assay is not interfered by the endogenous cystathionine and therefore can be used with confidence in patients with renal disease.
