Phlebotomy Exam Prep 39, Cold Agglutinin Specimen Handling

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: - Cold agglutinin tests demand a pre-warmed red-top tube that is kept at a constant 37°C. - Allowing the specimen to cool causes red blood cells to agglutinate, or clump together. - RBC clumping results in falsely decreased red blood cell counts and falsely increased MCV. - Never confuse the warm handling required for cold agglutinins with tests that require chilling, such as ammonia. - The entire process, from collection through transport and centrifugation, must be maintained at body temperature to ensure accurate results.
