## 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 GTT protocol begins with a mandatory 8 to 12-hour fast before the baseline draw. - A 75-gram glucose load is standard, while a 100-gram load is typically used for gestational diabetes testing in pregnant patients. - Timed draws start immediately after the patient finishes the glucose drink, not when they begin. - If a patient vomits, the test is usually invalid and must be documented and rescheduled. - Gray-top tubes containing sodium fluoride are required for all GTT specimens to prevent glycolysis and ensure accurate results.
