Karen – I assume from the question this is for unregulated testing?

For saliva testing, here would be no reason you could not use standard STT procedures as outlined in the CFR. Having BATs/STTs trained under federal protocol is good practice for unregulated testing programs because the protocols ensure integrity of the results (and give you a leg to stand on if an adverse employment action were challenged).

The advisability of blood collection will depend upon your employer policies and state regulations, and it cannot be used for routine DOT screens of course. I disagree with Dr. Rodway on the “assault” characterization – if legal in your state and supported by thoughtful policy, one could certainly use blood alcohol in non-regulated testing – for example reasonable suspicion with shy lung, or if you don’t have ability to do BATs. And actually there are states (Minnesota being one) that prohibit employers collecting breath alcohol on the premises, but will allow blood testing in a lab. Assuming you have collectors already trained in phlebotomy, you could overlay the chain of custody procedures as you would use for a urine collection. Work with your lab to see if they support chain of custody and request they provide a CCF.

The lab you are using for the hair testing likely has their own collection protocol. There is training available for that if you decide to collect your own – the lab may be able to point you to training.

Actually only Matrix permitted in Maryland - also required by FRA as post accident
