Abstract

The present disclosure provides a method (400) of evaluating a fluidic substance (10) having particles (11). The method (400) comprises capturing a reference image (202) of at least a portion of a container (102) that is in an empty state; determining a reference grayscale value (V1) of at least a portion of the reference image (202); aspirating a volume of the fluidic substance (10) into the container (102); capturing a test image (252) of the container (102) containing the aspirated volume of the fluidic substance (10); determining a test grayscale value (V2) of at least a portion of the test image (252); calibrating a universal calibration curve (56) relating particle concentration and grayscale value based on the reference and test grayscale values (V1, V2); and determining a particle concentration (P1) in the fluidic substance (10) based on the test grayscale value (V2) and the calibrated universal calibration curve (60).
