Question:
During allergic conditions which of the following increase in number?
During allergic conditions which of the following increase in number?
Show Hint
Allergy marker: Eosinophils (acidophils) ↑ in allergies and parasitic infections.
Updated On: May 4, 2026
- Cyanophils
- Acidophils
- Neutrophils
- Lymphocytes
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Allergic reactions involve immune responses where specific white blood cells increase in number.
Step 1: Understand role of WBCs in allergy.
• Eosinophils (also called acidophils) → Increase during allergic reactions and parasitic infections
• Neutrophils → Fight bacterial infections
• Lymphocytes → Involved in adaptive immunity
Step 2: Identify correct cell type. Acidophils (eosinophils) release histamine-modulating substances and are commonly elevated in allergic conditions.
Step 3: Analyze options.
• (A) Cyanophils → Not a standard category $\times$
• (B) Acidophils → Increase in allergies \checkmark
• (C) Neutrophils → Bacterial infection $\times$
• (D) Lymphocytes → General immune response $\times$
Step 4: Conclusion. \[ \text{Acidophils increase during allergic conditions} \]
