Summarize the normal and abnormal ranges for ESR, RBC count, WBC count, and DLC from the provided document.

Here is a summary of the physiological parameters and their normal/abnormal ranges from your document:

2. Erythrocyte Sedimentation Rate (ESR)

• Westergren Method:
  • Male: $0 - 15 \text{ mm/hr}$
  • Female: $0 - 20 \text{ mm/hr}$ (Higher in females due to lower RBC count/less 'crowding' and higher fibrinogen).
• Abnormal:
  • Markedly High ($>100 \text{ mm/hr}$): Multiple myeloma, temporal arteritis, or severe infection.
  • Low (near 0): Polycythemia, sickle cell anemia, or congestive heart failure.

3. Total Red Blood Cell (RBC) Count

• Male: $4.5 - 6.0 \text{ million/mm}^3$
• Female: $4.0 - 5.5 \text{ million/mm}^3$
• Abnormal:
  • Low: Anemia (look for signs of low $\text{O}_2$ transport).
  • High: Polycythemia Vera or chronic hypoxia (e.g., COPD).

4. Total White Blood Cell (WBC) Count

• Adults (Both Genders): $4,000 - 11,000 \text{ cells/mm}^3$
• Abnormal:
  • Leukocytosis ($>11,000$): Infection, inflammation, or leukemia.
  • Leukopenia ($<4,000$): Bone marrow depression, viral infections (e.g., HIV), or chemotherapy.

5. Differential Leukocyte Count (DLC)
Ranges are usually percentages of the total WBC count:

• Neutrophils: $40\% - 75\%$ (High: Bacterial infection)
• Lymphocytes: $20\% - 40\%$ (High: Viral infection)
• Monocytes: $2\% - 10\%$ (High: Fungal/Chronic infection)
• Eosinophils: $1\% - 6\%$ (High: Parasites/Allergy)
• Basophils: $<1\%$ (High: Rare; Allergic reactions/Leukemia)

6. Bleeding & Clotting Times

• Bleeding Time (Ivy Method): $2 - 9 \text{ minutes}$
  • Abnormal ($>9 \text{ mins}$): Thrombocytopenia or aspirin use.
• Clotting Time (Capillary Tube): $3 - 8 \text{ minutes}$
  • Abnormal ($>10 \text{ mins}$): Hemophilia, Vitamin K deficiency, or Liver disease.

7. Body Mass Index (BMI)

• Underweight: $<18.5 \text{ kg/m}^2$
