Abstract
An automated system captures multiple digital images of a sample, from different viewing areas of the sample. The images are analyzed and a test result may be reported based on the count of cells in all of the digital images. The system may be especially applicable to the testing of samples having low cell concentrations, as the variability between tests may be reduced as compared with a system that bases its test results on only a single image of the sample. The system may count the cells in a first digital image of the sample, and may capture or analyze one or more additional digital images only when it is recognized that additional measurements are needed to ensure adequate accuracy and repeatability of the test.
