Clinical Laboratory Medicine, a free health course on Tomo

Clinical Laboratory Medicine

Bridge the gap between raw biological samples and diagnostic decisions. Learn to catch hidden specimen artifacts, interpret complex panel patterns, and navigate assay interferences.

Like Duolingo, but for Clinical Laboratory Medicine. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Decoding Panels and Catching Artifacts and Diagnostic Traps and Analytical Precision. It assumes you already know the basics.

What you'll learn

Key ideas in Clinical Laboratory Medicine

  • Normal gap points to direct bicarbonate loss through gastrointestinal diarrhea or renal wasting.
  • High gap shows unmeasured anions like ketoacids or toxic metabolites consumed bicarbonate.
  • Hypoperfusion triggers avid proximal tubular reabsorption of urea while creatinine remains poorly absorbed.
  • Intrinsic parenchymal damage disrupts tubular integrity so urea reabsorption drops to baseline ratios.
  • Automated impedance counters misread aggregated platelet clumps as single lymphocytes.
  • Smear examination confirms clumps; redraw in sodium citrate tube establishes accurate platelet count.
  • Contracted plasma volume artificially elevates non-permeable solutes through hemoconcentration.
  • Rehydrating the patient normalizes circulating plasma water and reveals true baseline analyte levels.
  • Microcytic indices focus laboratory evaluation on iron stores and globin chain synthesis.
  • Normocytic indices require reticulocyte testing to separate marrow failure from peripheral destruction.
  • Macrocytic indices prompt direct assay of DNA synthesis cofactors like vitamin B12 and folate.
  • Ruptured erythrocytes spill concentrated intracellular potassium into surrounding serum
  • Lactate dehydrogenase and AST are rich inside red cells and falsely spike upon lysis
  • Extracellular sodium remains largely unaffected because intracellular red cell stores are low
  • Drawing blood above an active line dilutes native analytes with the carrier solution
  • A dextrose infusion dilutes serum electrolytes while manufacturing extreme hyperglycemia
