“…Serial dilution, also called limiting dilution series, is a standard laboratory procedure; [19] the objective of the serial dilution method is to estimate the concentration (number of colonies, organisms, bacteria, or viruses) of an unknown sample by counting the number of colonies cultured from serial dilutions of the sample, and then back track the measured counts to the unknown concentration. Serial dilution techniques are routinely used in hospitals, public health, virology, immunology, and microbiology.…”
