T-2 mycotoxins and Yellow Rain; the same destructive neurological agent that is found in indoor molds. Screening methods such as ELISA kits are commonly used to rapidly detect mycotoxins. A majority of mycotoxin exposures are through food ingestion or airborne exposure. The most appropriate method depends on the intended use of the results - for example, is a qualitative ("yes/no") result sufficient, or is exact quantitation (concentration) needed?. These tests are simple and can be used on the farm relatively easily. It is important to not rely solely on visual methods, such as the blacklight test, for confirmation of mycotoxins. A Single Cannabis LC/MS/MS Method to Meet California. Types of mycotoxins. Rapid testing methods such as chromatography and spectroscopy techniques are used to ensure timely analysis of a larger sample size, and thereby offering market growth opportunities in order to reduce the time for mycotoxin testing By sample, the food segment is projected to account for a larger share in the mycotoxin testing market. Federal Grain Inspection Service. FGIS has implemented a program to verify the performance of rapid tests for mycotoxins in grains.
