Calm the cat by gently caressing it, while finding a suitable spot to prick. A good spot is usually in the ear of the animal, in the area between the vein and the outer edge, halfway up (Fig 3). Alternative sites can be the limbs, foot pads, or lips.
To allow for a good blood flow, massage and warm the site for skin puncture for 3–5 min. If using a heating pad, make sure the temperature does not exceed 40°C to prevent harming the animal. Add a thin coat of Vaseline™ to the pricking-site
to prevent blood from dispersing into the fur. Take a firm grip of the limb to be pricked. If pricking-site is on the ear, make sure to have a tissue/gauze as backing while performing the prick. Make a quick and firm puncture using an ultra-fine or fine tip lancet.
Wipe of the first drop of blood with a clean tissue. When the second drop forms, collect the blood in a Boule plastic micropipette. Completely fill
the micropipette and make sure there is no air trapped inside. Carefully wipe of any excess blood on the outside of the micropipette and place the filled micropipette into the MPA adapter.
Insert the adapter into the analyzer, an analysis cycle will automatically begin. Note! Samples should be analyzed immediately after collection, for optimal
results, no longer than 10 min from collection.

To ensure an accurate platelet count in cats, consider the following:
Choose an instrument optimized for your needs – Exigo H400 features:
• MPA inlet for capillary blood sampling allows for a less stressful sampling method for the animal
as well as a minimized sample volume, suitable for smaller animals such as cats.
• Capillary tubes, with maximized surface-to-volume ratio, are internally coated with EDTA to
minimize possible clotting during collection.
• Narrow cell count aperture to increase the sensitivity when counting smaller corpuscules such
Pointers for pre-analysis:
• Make sure the animal is calm and find a good pricking spot.
• Ensure a good blood flow through massaging and warming.
• Apply Vaseline to pricking area, to hinder the blood from dispersing into the fur.
• Make a firm and precise puncture with a fine lancet.
• Wipe away the first drop of blood, as this may contain debris from the puncture and interstitial
fluid affecting the cell count.
• Perform the analysis without delay, for optimal results, no longer than 10 minutes after puncture.
