These tests are done on serum or plasma and, therefore, are not done on whole blood. The use of serum or plasma will cause the test result to be 18% +/- 3% above whole-blood readings done in crime labs by a GC/MS. These assays are available in kit form. They can be done manually or can be automated. These tests are preferred in...
