If RBCs are the carriers, then WBCs are the warriors. They protect you from infections and keep your immune system strong.
⚪️ What are WBCs?
White Blood Cells are a group of cells that fight infections, heal injuries, and maintain immunity. There are different types — like neutrophils, lymphocytes, and monocytes — each with its own role in defense.
📊 Normal WBC Range
-Adults: 4,000 – 11,000 cells/µL of blood
📉 What happens if WBC count is low?
Low WBC count means your defense army is weak. Causes include:
-Viral infections (like flu, dengue)
-Side effects of chemotherapy
-Bone marrow problems
-Autoimmune conditions
Symptoms may include: frequent infections, fever, fatigue.
📈 What happens if WBC count is high?
High WBC count usually means your body is fighting something. Causes include:
-Infections (bacterial, viral, or fungal)
-Inflammation (like arthritis)
-Allergies
-Certain cancers like leukemia
👉 Takeaway: WBCs are your immune strength indicator. A sudden rise or fall in values should not be ignored.
