Anticoagulant Rodenticides (LC/MS)

Measurement of anticoagulant rodenticides by liquid chromatography/mass spectrometry. Targets include warfarin, bromadiolone, brodifacoum, diphacinone, chlorophacinone, coumatetralyl, difenacoum, difethialone, coumachlor, and dicoumarol.

One or more of the following: 

• 2 mL EDTA whole blood
• 2 mL heparinized whole blood
• 2 mL serum
• 10 g fresh liver
• 10 g bait

Do not submit liver in formalin. 

Do not centrifuge whole blood samples. 

Serum should be centrifuged and removed from the clot.

• Tissue or bait: sealed, leak-proof plastic container or bag. 
• Blood: EDTA (purple top) or heparinized (green top) tube. 
• Serum: remove from red cells and place sample in an additive free transport tube.

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.
