Anyway, can you tell me what that rating is based on please?
Of course. We base your rating on the evidence you give us like a doctor's report or medical test results and the results of your VA claim exam also called a compensation and pension, or C&P, exam, if we determine you need this exam.
Now for the advantages I'd get if I volunteered for chemical and biological testing studies. if I have any concerns or need assistance in obtaining medical treatment.
