Test Principle:In alkaline media, potassium ions in serum samples treated by protein precipitates can react with NA-TPB to generate turbid and stable suspensions. The turbidity is proportional to the potassium ion concentration in the sample..
Precision: Intra-Assay CV: <4%Inter-Assay CV: <6%
Storage and Stability:Store powder at 4°C liquid at -20°C. Store other components at 4°C. Stable for at least 6 months For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
