Microbial Identification techniques have been recently revolutionized by the development of genotypic methods. Quadrants Scientific has validated two complementary genotypic methods, DNA Sequencing and Riboprinting, to precisely ID your routine and most fastidious isolates including bacteria, yeasts and filamentous fungi. In our 20+ years of doing microbial identifications both genotypically and phenotypically, we have tested over 31,000 samples and absolutely see the clear advantage of the genotypic methods. In fact, the US Food and Drug Administration (FDA) strongly recommends the use of genotypic ID methods in its publication.

“Genotypic methods have been shown to be more accurate and precise than traditional biochemical and phenotypic techniques. These methods are especially valuable for investigations into failures (e.g., sterility test; media fill contamination).”
