Vetscan HM5 Sample Collection| Zoetis

Keys to successful sample collection

The quality of the sample analyzed is directly related to the quality of the result.

Use the largest vein and needle appropriate for blood collection
Avoid use of any needle smaller than a 23 gauge (though certain exotic species may require a smaller needle)

Use minimal alcohol on fur/skin
Remove the needle from the syringe before dispensing into the blood tube unless using a closed vacuum blood collection system

Immediately after filling tube, cap the tube and invert 15-20 times to sufficiently mix with anticoagulant (more inversions would be needed in case of 0.25 mL, 0.5 mL or 1.3 mL tubes)

Select tubes based on the testing requirements and size of patient (Microtainer^®, 1.3 mL, 3 mL, 5 mL)
Ensure tubes have not expired
Always fill blood tubes in the correct order to avoid contamination

EDTA (ethylenediaminetriacetic acid) contamination of chemistry samples may affect electrolyte results and cause a falsely low Ca (calcium) and falsely high K+ (potassium)
If improper tube-filling order occurs, the sample should be redrawn

For feline samples collected from the medial saphenous vein, a vacuum blood collection system instead of a syringe is recommended
