Distance and Colour-based Scores for Blood Test Risk Stratification

We introduce a numerical and a colour-based risk stratification score to quantify abnormal blood analyte values. The score indicates how removed values of an individual are from considered healthy ranges from the literature or derived from empirical data such as medical surveys. The scores behaviour can be adjusted to incorporate medical knowledge by assigning multipliers or weights to individual components and is rooted on a numerical and a colour-based scheme. We test the score against real and synthetic data from medically relevant cases, extremes cases, and empirical blood cell count data from the CDC NHANES survey spanning 13 years, from 2003 to 2016. We find that both the numerical and colour-based scores are informative in distinguishing healthy individuals from those with diseases manifested with abnormal blood results.
