Clinical Chemistry

Study lessons

1. 1

   Carbohydrates and glucose metabolismFree sample

   Covers how the body controls blood glucose, the criteria and tests that diagnose diabetes, hypoglycemia and hyperglycemia, the methods and specimen rules that keep a glucose result true, and the ketones of diabetic ketoacidosis.

   15 min
2. 2

   Lipids, proteins, and diagnostic enzymes

   Explains the lipoprotein classes and the Friedewald LDL calculation, total protein with the albumin to globulin split, and how the diagnostic enzymes ALT, AST, ALP, GGT, CK, CK-MB, LDH, amylase, lipase, and troponin point to specific organs.

3. 3

   Renal function, electrolytes, and acid-base balance

   Covers urea and creatinine as kidney markers with the clearance calculations, uric acid, the major electrolytes with the anion gap, and how to read the four acid-base disorders from a blood gas.

   15 min
4. 4

   Endocrinology, therapeutic drug monitoring, and toxicology

   Covers thyroid and adrenal feedback, reproductive hormones and tumor markers, the peak and trough logic of therapeutic drug monitoring, and the classic toxins carbon monoxide, lead, alcohol, and acetaminophen.

5. 5

   Quality control and instrumentation

   Covers accuracy versus precision with the mean, SD, and CV, the Levey-Jennings chart and Westgard rules, diagnostic sensitivity and specificity, and the working principles of spectrophotometry, electrophoresis, chromatography, and ion-selective electrodes.
