This invention relates to a novel, fully automated spectrophotometric analyzer and method used for testing blood samples in the clinical laboratory for thrombosis and hemostasis properties. The analyzer tests samples in a fully randomized format, and is fully automated in the areas of specimen handling, sample preparation, optical inspection, data analysis and total quality control for imprecision and bias.

Method and instrument for automatically performing analysis relating to

An endpoint assay for measuring fibrinogen utilizing strong thrombin and weak plasma. In a preferred embodiment the assay is based on the direct conversion of a normalized signal from a sensor to fibrinogen concentration.

Direct fibrinogen assay

A cleaning apparatus for cleaning delivery probes used for dispensing protein-containing reagents. The apparatus includes: a bath of a cleaning solution for a protein-containing reagent; a device for lowering the probe into the cleaning solution for aspirating cleaning solution into the probe and for coating the outside of the probe; a device for raising the probe from the cleaning solution; a device for forcing primer liquid through the probe for expelling aspirated cleaning solution followed by primer liquid from the probe for washing the inside of the probe; and a device for deflecting cleaning solution and primer liquid expelled from the probe onto the outside of the probe for washing the outside of the probe.
