Abstract
An automated method for assuring sample adequacy. The method includes providing a sample in a testing container, activating an illumination source to pass an illumination beam through the testing container and into the sample, and detecting an intensity of an emitted beam. The emitted beam includes at least a portion of the illumination beam that has been scattered by the sample. The method also includes generating a sample turbidity measurement based on the intensity of the emitted beam, and determining, based on the sample turbidity measurement, an adequacy of the sample to provide accurate results in a primary test.
