Abstract
Systems, methods and apparatus for determining an amount of blood in a blood culture are provided where an initial biological state and then periodic measurements of the biological state of the culture are taken. For each respective measurement, a normalization relative value between the respective measurement and the initial measurement is made thereby forming normalization relative values. For each interval of time points represented by the normalization relative values, a first derivative of the normalization relative values in the interval is made thereby forming a plurality of rate transformation values. For each set of rate transformation values in the plurality of rate transformation values, an average relative transformation value is computed, thereby forming average relative transformation values. A lookup table that matches a measure of central tendency of the average relative transformation values to a blood amount is used to determine the amount of blood in the culture.
