Testing of samples is generally performed as described below.
A screening analysis is performed for both ethanol and drugs if both types of testing are requested. Confirmation testing is performed for all positive screening results. If testing for ethanol and drugs is requested, the testing will be performed in parallel. As such, individual reports will be issued for the ethanol and drug testing. Drug testing usually takes longer for completion than the ethanol testing; therefore, ethanol reports will normally be issued before the drug report. Refer to the testing panel on the report for information related to the substances (drugs and alcohol) included in the testing, the screening and confirmation cutoffs, units of reporting, and the instrumentation used to perform each type of test.
If additional testing is requested, after the original toxicology report has been issued, a second report will be issued containing the original testing results plus the results from the additional testing.
Note if there is not enough sample to complete the confirmation testing, the result for the group will be QNS (Quantity Not Sufficient).
