BANA test
The BANA test (referring to the
bacteria, e.g. Prophyromona gingivalis, Treponema denticola, and Bacteroides forsythus (Red complex) produce waste products that are quite odiferous, and as a result contribute to bad breath.[1]
When a sample of a patient's saliva that contains these bacteria is placed within the BANA testing compound, it causes the breakdown of the N-benzoyl enzyme. As a result of this biodegradation occurs, the test compound changes color, indicating a positive reaction.[2]
Uses: Used to identify volatile Sulphur compounds in halitosis patients.
