2. Physiological Factors Affecting ESR
3. Clinical Significance
4. Interpretation and Limitations

Sub-Branches:

Principle and Methodology:

• Westergren Method
  • Measurement of ESR using Westergren pipette
  • Principle of sedimentation  is based on the fact that red blood cells settle to the bottom of the tube due to gravity, while the plasma remains on top.
• Wintrobe Method
  • Measurement of ESR using Wintrobe tube
  • Principle of sedimentationis similar to the Westergren method, but the Wintrobe method uses a shorter tube and a different anticoagulant.
• Automated Methods
  • Automated ESR analyzers use a variety of methods to measure the rate of sedimentation, including:
    • Optical detection: measures the change in optical density as red blood cells settle to the bottom of the tube.
    • Electrical impedance: measures the change in electrical impedance as red blood cells settle to the bottom of the tube.
    • Ultrasonic detection: measures the change in ultrasonic signals as red blood cells settle to the bottom of the tube.
  • Principle of sedimentation is the same as for manual methods, but automated methods use advanced technology to measure the rate of sedimentation more quickly and accurately.

Physiological Factors Affecting ESR:

• Rouleaux Formation
  • Aggregation of red blood cells
  • Increased ESR
• Plasma Viscosity
  • Increased plasma viscosity
  • Increased ESR
• Red Blood Cell Size and Shape
  • Abnormal red blood cell size and shape
  • Altered ESR
• Inflammation and Infection
  • Increased ESR in response to inflammation and infection
  • Acute phase response

Clinical Significance:

• Inflammatory Disorders
  • Elevated ESR in inflammatory disorders
  • Monitoring disease activity
• Infectious Diseases
  • Elevated ESR in infectious diseases
  • Monitoring disease activity
• Cancer
  • Elevated ESR in cancer
  • Monitoring disease activity
• Rheumatological Disorders
  • Elevated ESR in rheumatological disorders
  • Monitoring disease activity

Interpretation and Limitations:

• Normal Range
  • Normal ESR values
  • Age and sex-specific values
• Interpretation of Results
  • Elevated ESR in disease states
  • Monitoring disease activity
• Limitations of ESR
  • Non-specificity of ESR
  • Interference with other laboratory tests

This mind map provides a comprehensive overview of the principle and methodology of ESR, physiological factors affecting ESR, clinical significance of ESR, and interpretation and limitations of ESR. It can be used as a study aid or a reference tool for understanding the physiology of ESR.
