Study Notes
Overview of Clinical Biochemistry
- Clinical biochemistry is the branch of chemistry that focuses on the analysis of bodily fluids to diagnose and monitor diseases.
- It involves the study of metabolites, hormones, enzymes, and proteins in biological samples.
Key Components
-
Body Fluids Analyzed
- Blood
- Urine
- Cerebrospinal fluid (CSF)
- Saliva
- Synovial fluid
-
Common Tests
- Blood glucose levels
- Liver function tests (ALT, AST, bilirubin)
- Kidney function tests (creatinine, urea)
- Lipid profile (cholesterol, triglycerides)
- Electrolyte panels (sodium, potassium, chloride)
Importance
- Diagnosis: Identifies conditions such as diabetes, liver disease, and kidney dysfunction.
- Monitoring: Tracks disease progression and treatment effectiveness (e.g., diabetes management).
- Prognosis: Assists in predicting disease outcomes based on biochemical markers.
Metabolic Pathways
- Homeostasis regulation (e.g., glucose metabolism)
- Lipid metabolism and its relation to heart disease
- Protein metabolism and implications for renal function
Biochemical Markers
-
Enzymes: Elevated or decreased levels indicate various diseases.
- Example: Elevated troponin levels indicate myocardial infarction (heart attack).
-
Hormones: Hormonal imbalances can diagnose endocrine disorders.
- Example: Thyroid function tests (T3, T4, TSH) for thyroid disease.
- Proteins: Specific proteins serve as disease markers (e.g., C-reactive protein for inflammation).
Analytical Techniques
- Spectrophotometry: Measures concentration of chemical substances in a solution.
- Chromatography: Separates mixtures for analysis of individual components.
- Immunoassays: Utilizes antibodies for specific analyte detection (e.g., ELISA).
Quality Control
- Essential to ensure accurate, reliable test results.
- Involves calibration of instruments and control samples.
Emerging Trends
- Use of biomarkers for personalized medicine.
- Integration of genomics and proteomics in clinical biochemistry.
- Development of point-of-care testing for rapid diagnosis.
