dilution test

A dilution test is a method used to determine the strength or concentration of a substance, often in the context of medicine or microbiology. In this test, a sample is systematically diluted in a solvent, typically water or broth, to find the smallest amount of the substance needed to achieve a specific effect, like inhibiting bacterial growth. By observing how effectively the diluted samples perform, researchers can gauge the potency of the original substance and assess its potential applications or effectiveness in treating conditions.
