Verichem Laboratories now offers medical laboratory professionals a multi-level set of liquid stable and ready-to-use clinical reference materials for microprotein testing. These products are intended for the calibration verification of clinical systems testing for total protein and albumin in both urine and cerebral spinal fluid (CSF) samples. 

Accurate measurement of microprotein and microalbumin levels in urine are useful in the early detection of kidney damage while testing CSF is useful in uncovering abnormalities within the central nervous system. As such, the availability of these materials aims to address the needs of a wide variety of laboratory professionals, including those involved with routine clinical testing, medical research applications, and the development and manufacturing of IVD products. 

Suitable for use with both turbidimetric and colorimetric test methodologies, Verichem clinical reference materials for microprotein incorporates human protein components for optimum reactivity. The five-level set of materials provides 10 individual component concentrations in total. Each of the verified gravimetric concentration levels employ a distinctive set point design with equidistant target concentrations to address the current CLIA requirements for clinical system accuracy, sensitivity, linearity, and reportable range.
