CBC (Complete Blood Count) ek common blood test hai jo aapke blood ke major components ka snapshot deta hai. Aksar reports me numbers dekhkar anxiety ho jaati hai, par basic understanding se clarity milti hai.
Hb (Hemoglobin):
Oxygen carrying capacity. Low Hb = anemia (thakaan, weakness, dizziness). Causes: iron deficiency, B12/folate deficiency, heavy bleeding. High Hb dehydration ya smoking se bhi ho sakta hai.
WBC (White Blood Cells):
Body defense. High WBC infection/inflammation ka sign ho sakta hai. Low WBC kuch viral infections ya medications se.
Platelets:
Blood clotting. Low platelets me bruising/bleeding risk; high platelets sometimes inflammation/iron deficiency me.
CBC me aur bhi markers hote hain:
- RBC count, MCV (cell size), MCH—anemia type identify karne me help
- Neutrophils/lymphocytes—infection pattern suggest karte hain
Important: CBC akela diagnosis nahi. Doctor symptoms + history + other tests ke saath interpret karta hai. Example: mild low Hb + low MCV often iron deficiency suggest karta hai, but confirmation ke liye ferritin test useful hota hai.
Agar report me “slightly out of range” ho, panic mat karo. Repeat test, hydration, recent infection—sab numbers ko affect karte hain. But agar extreme values, persistent weakness, unexplained fever, bleeding, ya weight loss ho—doctor consult zaroor karo.
