Phlebotomy Exam Prep 40, Light-Sensitive Specimens

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: - That light exposure causes photodegradation, which leads to falsely low test results for sensitive analytes. - The most common light-sensitive specimens you must know for the exam are bilirubin, vitamin A, vitamin B12, beta-carotene, and porphyrins. - The correct procedure for protecting a light-sensitive specimen is to use an amber-colored tube or to wrap the collection tube in aluminum foil immediately. - How exam questions may test this knowledge through direct identification or by presenting clinical scenarios involving erroneous results. - A common exam trap is confusing light protection with temperature requirements (chilled or warmed specimens) or forgetting that light exposure falsely lowers, not raises, the result.

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.

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.
