摘要:
Embodiments disclosed herein are directed to systems and methods for determining a presence and an amount of an analyte in a biological sample. The systems and methods for determining the presence of an analyte utilize a plurality of images of a sample slide including multiple fields-of-view having multiple focal planes therein. The systems and methods utilize algorithms configured to balance the color and grayscale intensity of the plurality of images and based thereon determine if the plurality of images contain the analyte therein.
