Polyphasic Analysis

Polyphasic Analysis

Occasionally fatty acid analysis and DNA sequencing can individually yield ambiguous or no-match results for identification. In such cases polyphasic analysis - combined fatty acid and DNA sequencing analysis - can provide additional information and produce a definitive identification.


The key benefits of polyphasic analysis are:


  • Confirmation of a definitive match resulting from one technique.

  • Resolution of a non-match; a second technique can yield a definitive match in cases where the first technique gives no identification.

  • Resolution of an inconclusive match; a second technique can yield a definitive match in cases where the first technique gives multiple possible identifications.

MIDI Labs is the first laboratory to offer polyphasic analysis for microbial identification. With a combined phenotypic and genotypic approach, polyphasic analysis provides you with the most thorough and reliable results.
