laboratory for DNA testing

Good morning,


as you know, I have had two proximus thamnophis for some time. As there are several subspecies but it is difficult to determine them visually, I am looking for a laboratory, no matter where it is located, in order to carry out a DNA test.
The laboratory in question must be able to identify the subspecies and therefore have the corresponding database (something that most do not have).


Does anyone know of a lab that can do this kind of analysis?
I can provide a moult, a blood test, saliva test or other since my veterinarian agrees to follow me in these steps.


Someone can help me ?
