Verichem Laboratories, Providence, RI, has released a ready-to-use, liquid stable microprotein standard kit intended for the calibration, or calibration verification, of total protein and albumin concentrations in both urine and cerebrospinal fluid.

The five-level set provides 10 individual certified concentrations in an azide-free liquid format, where all concentrations are assigned by definitive procedures using human protein components of known purity. Accurate measurement of microprotein and microalbumin levels in the clinical laboratory are extremely useful in the early detection of kidney damage, especially in individuals who are at risk, such as those with type 1 or type 2 diabetes or high blood pressure.

Suitable for use with both turbidimetric and colorimetric testing methodologies, the microprotein standard kit incorporates human protein components for optimum reactivity.  Each of the certified gravimetric concentration levels of these standards employs a distinctive set point design with equidistant target concentrations in order to address the current CLIA requirements for clinical system accuracy, sensitivity, linearity, and reportable range.
