Drug Screen – Beta Agonists in Serum/Urine/Feed (LC/MS)

Detection of performance enhancing beta-agonist drugs by liquid chromatography / mass spectrometry.  Targets include albuterol, clenbuterol, formoterol, metoprolol, ractopamine, terbutaline, and zilpaterol. A feed prep fee will be added to feed specimens.

• Mammalian species: 5 mL serum or 10 mL urine
• Feed: 20 g. 

Remove serum from red cells and place in an additive free transport tube.

• Serum: plastic or glass tube with no anticoagulant additives. 
• Feed or urine: sealed, leak-proof container. A feed prep fee will be added to feed specimens.

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

Label all samples. Ship serum or urine 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. 
 
Samples deemed suspicious from initial screening will be subject to confirmatory testing. This may add an additional 1-3 days to the listed turnaround time, depending on the availability of reference standards through approved vendors and the complexity of required analytical and extraction methods.
