Greetings Gang: Here is the recording of the live study session today, for your review at your leisure! We went over a mix of questions in Lab Ops, UA/Body Fluids, Micro, and Heme. 👇🏽 Click here to view the recording VIEW RECORDING - 84 mins (No highlights) Key Takeaways - LAP Score is the CML/Leukemoid Differentiator: A high LAP score (e.g., 155) indicates a leukemoid reaction (mature cells), while a low score is characteristic of CML (immature cells). - JAK2 Mutation is Not Exclusive to ET: The JAK2 mutation, often linked to Essential Thrombocythemia (ET), also occurs in Primary Myelofibrosis (PMF). The key differentiator is PMF's "marked marrow fibrosis." - Campylobacter Jejuni's Key ID: Identify C. jejuni by its growth at 42°C, oxidase/catalase positivity, and positive hippurate test. - Study Strategy is Critical: Use process of elimination and common sense. For complex questions, memorize 2–4 key biochemicals per organism to rule out incorrect choices. Topics Lab Operations & Safety - Electrical Safety: Use a non-conductive material (wood/plastic) to separate a victim from a live electrical line. - Patient ID: Acceptable identifiers are full name, DOB, and medical record number. A room number is insufficient and unsafe. - Bloodborne Pathogens: Prevent exposure with engineering controls (splash guards) and PPE (gloves, masks). Asking patients about their HIV/hepatitis status is unethical and a HIPAA violation. - Surface Decontamination: Clean work surfaces with disinfectant after any blood/OPIM spill and at the start of each shift. - Chemical Handling: Read a chemical's label before moving or opening it. Urinalysis & Body Fluids - Kidney Function: Kidneys maintain acid-base balance (via bicarbonate), produce hormones (renin, EPO), and regulate water/electrolytes. They do not reabsorb waste products. - Urine pH Indicators: The reagent strip uses methyl red (red/orange → yellow) and bromthymol blue (yellow → green/blue). - CSF Cell ID:
