Drug Screen – Performance Animals (LC/MS)

Detection of prohibited substances and permissible therapeutic drugs in livestock show or competition animals using liquid chromatography/mass spectrometry. This test is not available for horses intended for racing, whether in training or competition. This test is intended for groups of animals participating in shows or competitions. TVMDL may perform Drug Screen – Unknowns (1544) on any submission that does not appear to meet that criteria (e.g., single animal on a submission, no reference to recent show/competition).

One or more of the following: 

• 20 mL urine
• 5 g feces
• 10 mL serum

Each sample must be labeled with a number and a species only. Do not include exhibitor names on the sample or the paperwork. Sample containers must be secured with evidence/tamper tape. Place evidence tape over the lid, not around the lid, taking care to not conceal the sample ID.

• Serum: remove from red cells and place in an additive free container. 
• Urine or feces: sealed, leak-proof container.

All samples must be sealed with security tape to maintain chain of custody.

Label all samples. Ship overnight on cold packs.

The testing schedule reflects days that extractions are initiated. Samples must be received in the testing section by 3:30 pm the day prior to the scheduled test day, otherwise samples will be held until the next scheduled test day. Turnaround time represents the estimated number of business days needed for complete extraction, sample preparation, instrument analysis, quality review, and data interpretation.
   
Turnaround time may vary on large submissions and during peak show seasons. Samples deemed suspicious from initial screening will be subject to confirmatory testing. Turnaround time for confirmation can vary and may extend to several weeks depending on the availability of reference standards through approved vendors, the complexity of required analytical and extraction methods, and applicable safety or regulatory considerations. In some cases, consultation may be required prior to proceeding with confirmation, and confirmation testing may be delayed or declined based on these factors.
