Abstract

An apparatus and method for performing immunoturbidimetric measurements of plasma proteins on an apparatus used for measuring plasma and serum interferents are described.
Immunoturbidometric measurements are made on a sample in a disposable dispensing tip which acts as cuvette and reaction chamber. These features allow tests which are not available on general chemistry analyzers, to become available, and at the same time the apparatus can provide a screening system for serum and plasma interferents.
