Comparison of the Coag-a-mate Dual Channel with the Fibrometer

The Coag-a-mate Dual Channel is compared with the Fibrometer in performance of prothrombin time (PT) and activated partial thromboplastin time (APTT) for commercial controls and patient specimens. The precision of duplicate APTT measurements was significantly better for the Coag-a-mate Dual Channel. However, the precision of duplicate PT measurement was not different between the two instruments. Although the Coag-a-mate Dual Channel did not offer any time saving on single measurements, analysis time was considerably reduced with batches of three or more samples.
