Abstract: A chromatogram analysis tool receives blood test data for a sample and divides the data into regions and determines a best-fit match template for each region. The chromatogram analysis tool determines a best-fit match for each region by comparing the blood test data to a set of templates associated with archetypical shapes of the region. The template with the highest r-squared value for the blood test data is the best-fit template. The chromatogram analysis tool generates a report based on the best-fit match templates for each region, which can indicate medical conditions or recommendations for additional testing.
