Study Notes
Spectrophotometer
- A spectrophotometer consists of a light source, monochromator, sample cuvette, and detector
- It measures the absorbance of light by a sample to determine the concentration of an analyte
- Applications in clinical chemistry include:
- Measuring enzyme activity
- Determining blood glucose levels
- Analyzing protein concentrations
Electrophoresis
- Types of electrophoresis:
- Gel electrophoresis (separates DNA, RNA, and proteins based on size and charge)
- Capillary electrophoresis (separates charged particles in a capillary tube)
- Polyacrylamide gel electrophoresis (separates proteins based on size and charge)
- Applications:
- DNA sequencing
- Protein analysis
- Diagnosis of genetic diseases
Chromatography
- Categories of chromatography:
- Gas chromatography (separates volatiles based on boiling points)
- Liquid chromatography (separates solutes based on interaction with stationary phase)
- Thin-layer chromatography (separates solutes based on interaction with stationary phase)
- Role in clinical chemistry:
- Separates and identifies biological molecules
- Analyzes bodily fluids (e.g., blood, urine)
- Detects and quantifies drugs and toxins
Automation in Clinical Chemistry
- Automation refers to the use of machines and computers to perform laboratory tests
- Benefits:
- Increased efficiency
- Improved accuracy
- Reduced labor costs
- Examples of automated systems:
- Automated analyzers
- Robotics
Osmometry
- Principle: measures the concentration of particles in a solution by detecting changes in osmotic pressure
- Significance in clinical chemistry:
- Measures serum osmolality to diagnose and monitor hydration status
- Determines urinary osmolality to evaluate kidney function
