In this episode you will learn:

- The critical differences between the capillary and venipuncture orders of draw.

- Why EDTA (lavender/pink top) tubes are collected first after blood gases in a capillary draw to prevent platelet clumping.

- How an incorrect capillary draw order can lead to falsely low platelet counts and inaccurate CBC results.

- That serum (red/gold top) tubes are always collected last in a capillary puncture because they are designed for clotted blood.

- A mnemonic to remember the correct order: "Good Exams Always Score" (Gases, EDTA, Additives, Serum).
