Requests for Analysis

ISDT tests whole blood, serum, and plasma. The drugs included in ISDT's testing panels are listed at: A request for analysis of a specimen other than whole blood, serum, or plasma or outside the scope of ISDT's alcohol or drug panels will not be completed. A Toxicology Analysis Request Form must be submitted to ISDT prior to analysis being initiated. A request to add an ISDT alcohol or drug panel to a case already submitted to ISDT must be in writing.

If specimens are submitted for alcohol and drug testing in non-fatal/serious bodily injury (SBI) traffic-related cases, alcohol testing will be performed first. If the subject blood alcohol concentration is ≥ 0.10 g/100 mL blood, the request for drug analysis will be canceled.

ISDT requests to be notified if a pending analysis is no longer needed. Withdrawal of a request for analysis must be in writing. When a request for analysis is modified or withdrawn, ISDT will document the request in the case file.

Requests for testing outside the scope of ISDT's panels:
