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.

Analysis apparatus for providing an indication determinative of the coagulation time of a blood sample, comprising: a plurality of detector means each separate one associated with a separate one of a plurality of test chambers with each of said detectors providing a signal indicative of a clot formed in an associated chamber, selector means for selecting a predetermined number indicative of the number of clots to be detected in said plurality of chambers, during an analysis, comparison means responsive to said signals from said detectors and said selected predetermined number to provide an output signal when they are equal, and, timing means operative to commence operation when said samples are distributed in said test chambers and responsive to said output signal to terminate operation upon the generation of said output signal to cause said timing means to indicate the time interval manifesting the formation of said selected number of clots.
