## Resource

This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. 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).
