Hi, Edward.

I have no idea if there is a commercially available test for BDNF genotypes. I never looked into it. I don't think there has been a prospective investigation to study the prognosticative value of testing for genotype in advance of ketamine treatment.

The majority (66%) of people have the val66val allele for the BDNF (brain-derived neurotrophic factor) gene. These are the full remitters to ketamine. Then, there are those who have val66met. These people are partial responders only. The minority who have the met66met allele are non-responders.
