Total IgE Level

• Overview: Measures the total amount of IgE antibodies in the blood, indicating overall allergic sensitivity.

Complete Blood Count

• Overview: Measures the percentage or absolute number of eosinophils in blood, a type of white blood cell involved in allergic reactions and parasitic infections.

Total IgE Level

• • Risk Assessment: Helps screen for atopic conditions like asthma, eczema, allergic rhinitis.

Eosinophil Count

• • Risk Assessment: Helps assess severity and activity of allergic or parasitic conditions.

Total IgE Level

• Normal Range: Usually < 100–150 IU/mL (varies by lab and age)

Immunoglobulin E (Specific IgE)

• Normal Range: Negative or below lab-specific cutoff (usually <0.35 kU/L)

Eosinophil Count

• Normal Range: Typically 1–4% of total white blood cells or 100–400 cells/µL

Total IgE Level

• Interpretation:

  • Elevated levels suggest increased allergic activity or parasitic infection.

  • Low or normal levels do not exclude allergy.

•  

Immunoglobulin E (Specific IgE)

• Interpretation:

  • Positive test indicates sensitization to that allergen, supporting allergy diagnosis.

  • Does not always correlate with clinical symptoms (sensitization vs. allergy).

Eosinophil Count

• Interpretation:

  • Elevated eosinophils indicate allergic inflammation, asthma, parasitic infection, or some autoimmune diseases.

  • Normal levels do not rule out allergy.

Total IgE Level

• Sample Type: Serum (venous blood)

Eosinophil Count

• Sample Type: Whole blood (CBC with differential)
