The order of draw for capillary (skin puncture) collection differs from venipuncture. Which specimen is generally collected first from a capillary stick?

In capillary collection, blood gases are collected first, followed by EDTA (hematology) tubes, then other additive tubes, and serum last. EDTA is collected early to ensure an adequate, well-mixed hematology sample before the drop begins to clot. This order differs from venous draws, where the light blue coagulation tube comes early.
