In this episode, I continue our discussion of hematology as relevant to the USMLE Step 1 and largely conclude my discussion of platelets and their disorders. I also discuss some weird “systemic” diseases with hematologic findings that tend to show up on the USMLEs. Between Episodes 79/80, you should become a platelet expert. You can safely skip parts of the podcast where I begin to go into the pathophysiology underlying APLS. However, it may be a useful explanation for those thirsty for more understanding. I am also adding a small slide supplement that essentially describes APLS pathophysiology/testing in words.
