CBC, ESR

Fasting Required: No

Risk assessment

1. Complete Blood Count (CBC)

Risk Assessment:

• Helps detect:

  • Anemia (low RBC/Hb).

  • Infections (elevated WBC count).

  • Platelet abnormalities (risk of bleeding or clotting).

  • Leukemia or other bone marrow issues.

2. Erythrocyte Sedimentation Rate (ESR)

Risk Assessment:

• Used to evaluate:

  • Chronic inflammation (e.g., arthritis, lupus).

  • Infections.

  • Cancers.

  • Autoimmune conditions.

Ranges

1. Complete Blood Count (CBC):

Normal Ranges (may vary slightly by lab):

• RBC: 4.7–6.1 million/μL (men), 4.2–5.4 million/μL (women).

• WBC: 4,500–11,000/μL.

• Hemoglobin (Hb): 13.8–17.2 g/dL (men), 12.1–15.1 g/dL (women).

• Hematocrit (HCT): 40.7%–50.3% (men), 36.1%–44.3% (women).

• Platelets: 150,000–450,000/μL.

2. Erythrocyte Sedimentation Rate (ESR):

Normal Ranges (may vary slightly):

• Men: 0–15 mm/hr.

• Women: 0–20 mm/hr.

• Children: 0–10 mm/hr.

Test result interpretation

Complete Blood Count (CBC):

Interpretation:

• Low RBC, Hb, HCT: Anemia or blood loss.

• High RBC, Hb, HCT: Dehydration, polycythemia.

• High WBC: Infection, inflammation, leukemia.

• Low WBC: Immune suppression or marrow issues.

• Low Platelets: Risk of bleeding.

• High Platelets: Inflammatory disorders or clotting risks.

Erythrocyte Sedimentation Rate (ESR):

Interpretation:

• Elevated ESR: Indicates inflammation, infection, or autoimmune diseases.

• Normal or Low ESR: Likely no significant inflammation.

Sample types

Sample Type:

• Whole Blood: Collected in a black-top or lavender-top tube.
