BOERNE, TX – February 2, 2009 – Stanbio Laboratory, L.P., a leader in medical testing and diagnostic devices, is pleased to announce the immediate availability of a user defined application on the Dade Dimension® for their ß-Hydroxybutyrate assay.
The assay is used for the determination of ß-hydroxybutyrate (blood ketone) in serum and plasma specimens. The measurement of ß-hydroxybutyrate is essential for the identification of complications of diabetes mellitus. During periods of metabolic acidosis the concentration of ketone bodies increases in blood and urine due to the lack of sufficient glucose in the cells. The major ketone body ß-hydroxybutyrate (~ 75 %) is not detectable with test strips commonly used for the detection of ketone bodies in urine. The Stanbio test is specific for ß-hydroxybutyrate, the predominant ketone body. It is not affected by interfering substances and shows a high linearity of up to 4.5 mmol/L.
The reagent set requires no reagent preparation and is designed to be used in Reagent-Start (R1/R2) systems. The liquid, ready-to-use reagents are stable until their labeled expiration dates when stored at 2-8°C.
In the Stanbio Laboratory method, ß-Hydroxybutyrate in the presence of NAD is converted to acetoacetate and NADH at pH 8.5 by ß-Hydroxybutyrate dehydrogenase. At this pH, the reaction is favored to the right. The NADH produced reacts with INT in the presence of diaphorase to produce a color and is read at 505 nm.
When compared with another commercially available chemistry system the Stanbio ß-Hydroxybutyrate method showed a correlation coefficient of 0.99 and a regression equation of y = 0.954x - 0.051.
The Stanbio ß-Hydroxybutyrate LiquiColor® Reagent Set is available as a set – R1: 1 x 50mL, R2: 1 x 8.5mL – and includes a 1.0 mmol/L standard. Controls and linearity material are available separately.
