*Transport media containing charcoal is suitable for most samples with some notable exceptions such as Strangles PCR swabs. Check with your submitting lad the first time you collect a swab for a specific diagnostic test to see if there are any special transport medium requirements. CEMO swabs must be taken in charcoal.
