Abstract
A method for analysis of an aqueous sample includes determining a first reading of a sample, and comparing the first reading to a first read index to determine a first read probability wherein the first read probability gives either a positive or a negative result for the sample. The method includes determining a second reading for the sample, and comparing the second reading to a second read index, wherein a second read probability is determined according to the reading and the second read index. The second read probability gives either a positive or a negative result for the sample. From the first and second readings, a species and a life phase of the species are determined.
