Why would you expect capillary blood to hold a lower platelet count than venous blood?
I really gave no idea...
Answers:
Because capillary blood is taken by soft tissues being lance with a needle and the blood that oozes out human being collected. This blood has passed out of a hole created by damaging the tissue and has come into contact beside various substances that can trigger clotting (ATP, collagen, cell membrane components etc.) Therefore a certain amount of clotting is likely to enjoy taken place activating the platelets and causing them to aggregate on the surface of the damaged tissue as they flow out.
In contrast venous blood is taken through a syringe thus avoiding contact with the area of damage cause by the venepuncture, however insufficient mixing with the anticoagulant in the tube may still lead to clot formation within vitro, which also gives a lower platelet count.

You are constantly breaking capillary by scratching, banging, etc. your skin. Platelets are used to heal these tiny wounds formerly you even notice them. So, they are, in a sense, used up.
That is why people near low platelet counts often times get broken capillaries that form a rash-like formation.
