In this episode, I begin a comprehensive review series on Heme/Onc for the USMLE Step 1 Exam. This will ultimately be in about 5-10 parts (covering essentially all in FA for The USMLE Step 1, 2019 edition) but I should be able to cover the breath of Heme/Onc material as relevant to Step 1. In this podcast, I discuss platelets (and associated disorders) primarily but go on to integrate a lot of immunology, nephrology, and associated pharmacology. There are potentially 5-6 questions you would correctly answer on the exam as a result of this podcast. As an aside, there are already podcasts devoted to Heme-Onc Pharm and some heme pathologies (they are one of my earlier episodes). There are no attached slides.
