APPARATUS FOR PERFORMING OPTICAL MEASUREMENTS ON BLOOD CULTURE BOTTLES

摘要

An apparatus and method for rapidly distinguishing positive blood cultures from negative bloodcultures in sealable containers, and for determining the combination of blood volume and hematocrit in a sealable container. The apparatus comprises an optical source for illuminating the culture with a light beam under an oblique angle to generate an asymmetric spatial distribution of backscattered light, which is imaged onto an imaging detector connected to a data analyzer.
