Abstract
A sample of blood is divided into a plurality of isolated test chambers. The blood is mixed with additive reagent having previously been measured into each test chamber. A clot detector and analyzer system determines the time required for the blood-reagent mixture in each chamber to form a clot. In a first mode of analyzer system operation there is recorded the time required for a selected number of clots to be detected. A second mode of operation identifies those chambers in which clots have been detected within a specified time interval.
