Study Notes
Clinical Chemistry Overview
- Clinical chemistry analyzes bodily fluids (blood and urine) to diagnose, monitor, and manage diseases.
- It's vital for modern healthcare, providing crucial health insights.
Basic Principles
- Clinical chemistry studies chemical processes within the body.
- It analyzes various bodily fluids (blood, urine, etc.) to assess health.
- It uses diverse analytical techniques (spectrophotometry, chromatography, immunoassays, electrophoresis, molecular diagnostics) to precisely measure biochemical components.
- Analyzes blood glucose, cholesterol, kidney/liver function tests, electrolytes, hormones, and tumor markers.
Key Components
- Electrolytes: Sodium, potassium, chloride, and bicarbonate levels assess fluid balance and electrolyte imbalances.
- Metabolites: Glucose, cholesterol, triglycerides reveal metabolic health (e.g., diabetes).
- Proteins/Enzymes: Albumin and liver transaminases indicate organ function (liver, kidney).
- Hormones: Thyroid hormones, cortisol, and sex hormones diagnose endocrine disorders.
Clinical Applications
- Laboratory tests used to diagnose diseases, monitor treatments, and assess organ function.
-
Routine Panels: Assesses metabolic function, organ health, and disease states.
- Basic Metabolic Panel (BMP): Glucose, electrolytes (sodium, potassium, chloride), renal function (creatinine, BUN), sometimes calcium. Purpose: electrolyte balance, kidney function, blood glucose.
- Comprehensive Metabolic Panel (CMP): All BMP components + liver enzymes (AST, ALT, ALP), bilirubin, total protein, albumin, additional electrolytes (often calcium, bicarbonate). Purpose: evaluates liver function, kidney function, electrolyte balance, blood glucose, protein status.
-
Liver Function Tests (LFTs): Assess liver function, detect liver diseases (hepatitis, cirrhosis).
- Components: Liver enzymes (AST, ALT, ALP), bilirubin (total, direct, indirect), total protein, albumin, sometimes GGT.
-
Lipid Profile: Assesses cardiovascular risk, lipid metabolism.
- Components: Total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides.
-
Thyroid Function Panel: Assesses thyroid gland function.
- Components: TSH, T4, T3, sometimes thyroid antibodies (anti-TPO, anti-Tg).
-
Renal Function Panel: Evaluates kidney function, assesses renal health.
- Components: Creatinine, BUN, eGFR, sometimes electrolytes.
-
Electrolyte Panel: Assesses electrolyte balance, acid-base status, fluid balance.
- Components: Sodium, potassium, chloride, bicarbonate, maybe calcium, magnesium, phosphorus.
