Greetings Gang, We had our live study session today! Here is the recording AND the summary of what we discussed! See you on the next one! VIEW RECORDING - 102 mins (No highlights) Meeting Purpose Review random LabCE questions for ASCP exam prep. Key Takeaways - Leukoreduction vs. Irradiation: Leukoreduction prevents CMV transmission (virus is in WBCs) and febrile reactions. Irradiation is required to prevent Graft-vs-Host Disease (GvHD) by inactivating all immunocompetent lymphocytes, a step leukoreduction alone cannot guarantee. - ABO Discrepancy Types: Group 2 discrepancies are caused by weak or missing antigens (e.g., A subgroups, acquired B phenomenon), while Group 1 is from weak or missing antibodies (e.g., newborns, elderly). - Hemolytic Uremic Syndrome (HUS): A key diagnosis for a patient with fever, elevated BP, low platelets, and schistocytes, especially with a gram-negative rod infection (often E. coli O157). - Spectrophotometry & Electrochemistry: Stray light is the primary cause of Beer's Law deviation. Electrochemistry is the basis for potentiometry, amperometry, and coulometry, which measure ions and gases (e.g., PO2 electrode). Topics Blood Bank & Transfusion - Leukoreduction vs. Irradiation - Leukoreduction: Filters WBCs from blood products.Prevents: CMV transmission (virus is in WBCs) and febrile reactions (recipient anti-WBC antibodies). Ineffective against: GvHD (some WBCs can pass filter), malaria (in RBCs), and bacteremia (bacteria are too small to be filtered). Irradiation: Inactivates all immunocompetent lymphocytes.Required for: Preventing GvHD in immunosuppressed patients. - ABO DiscrepanciesGroup 1 (Weak/Missing Antibodies) - Causes: Newborns, elderly, immunodeficiency. Result: Weak or negative reactions in the reverse grouping.Group 2 (Weak/Missing Antigens): Causes: A/B subgroups, leukemia, acquired B phenomenon. Result: Weak or negative reactions in the forward grouping. - Antibody Screen Interpretation - A positive screen requires the corresponding antigen to be present on the screening cells. If an antigen is absent, the antibody cannot be the cause of the reaction.

Greetings Gang, I just dropped TWO of the most high-yield resources I’ve ever made: 🧫 Bacteriology Buzzwords Chart 🦠 Ultimate Parasitology Guide Both are quick, dirty, straight to the point... no textbook overload or extra nonsense you don’t need. These have the most heavily tested organisms, patterns, and clues you need to pass your board exam. 🔬🥳 LAB WEEK PRESALE DEAL Each guide: $5 (regularly $10) This is presale pricing from now until the end of Lab Week. It will NOT stay this low. (to find the charts, go to Classroom tab on the top of your screen) 📚 WHAT YOU’RE GETTING - High-yield organism charts - Straight buzzwords that actually show up on exams - Easy pattern recognition - Built for LAST-MINUTE review AND long-term retention 🎉 LAB WEEK KICKOFF SESSION We’re starting Lab Week RIGHT: 🗓 Monday 4/20 We’re having a FREE group session to kick everything off! I'm very excited for this one! ⚠️ DON’T MISS THIS... There will ALSO be: 🔥 A sale on the subscription to the Inner Circle community this weekend (right before Lab Week) Make sure you’re watching my Instagram and Facebook stories to click the sale link. To everyone who is studying hard... If you’ve been saying, “I just need something that makes this CLICK…” This is it. Love you all, super excited! xoxo, Marilyn

Hi everyone! Needing some advice please 🫶🏻 Micro has been kicking my buuuuutttt this semester to the point where I know my teacher doesn’t have hope in me 🥲 I’ve asked them for help but it’s pretty obvious , they get frustrated every time I do so, so I tend to just stay quiet and ask my other classmates for help. And that’s sad to say. I’ve tried taking my own notes , notebooklm , and now trying flashcards. I don’t know what else to do honestly 😭 I’m bummed out! It’s my final semester of my program and I want to prove her wrong! What else can you all recommend ? TIA!

Greetings Gang! 🤪😈 If you’ve been saying you need help studying for the ASCP or AMT exam… this is your sign to stop playing and get in. I’m hosting live study sessions every day THIS WEEK ONLY, and this is exactly how you should be studying: not alone, not guessing, but alongside people who are going through the same thing as you. MLS and MLT students all in one place, learning, asking questions, and actually understanding the material. Today is Day 4 of 7, about halfway through the week! Each session is focused on one topic and lasts about 1–2 hours. You do NOT have to stay the whole time. Pop in, learn what you need, and get out. orrrrrrrr... stay the whole time with MEEEEEE! Inside, I’m breaking things down in a way that sticks: • High-yield concepts • ASCP-style question breakdowns • Funny, memorable ways to actually retain the information And if you miss a session? All recordings are posted so you can go back and review whenever you want. ‼️ Right now you can join the Inner Circle with a 7-day FREE trial! Stop studying alone. Stop guessing. STOP FEELING LOST AND OVERWHELMED! Get in now and let’s get you to PASS. 🔬🧪 Click Here To Join The Inner Circle xoxo, Marilyn
