DiaSys proudly presents a new immunoturbidimetric test for prealbumin. The two-component, liquid-stable, ready-to-use reagent covers a very wide measuring range from 0.03 - 1.3 g/L; prozone security is given up to 2.6 g/L. Two different kits are offered, both designed for use on automated systems. The reagent is used with the calibrator set TruCal Protein containing five liquid stable calibrators at various levels. Alternatively TruCal Protein high can be used with automated systems which are able to pre-dilute the calibrator. The liquid-stable protein controls TruLab Protein Level 1 and 2 are available for use with the prealbumin reagent.
