Question

Normal haemoglobin level in adult male is _______

• A. \(8-10\)
• B. \(10-12\)
• C. \(13-17\)
• D. \(18-22\)

Hint:

Normal haemoglobin level in adult males is approximately \(13-17\) g/dL, while lower values may indicate anaemia.

Answer 1

The Correct Option is C

Concept:
Haemoglobin is the iron-containing protein present in red blood cells. It carries oxygen from lungs to tissues and also helps in carrying carbon dioxide from tissues to lungs.

Step 1: Understanding normal haemoglobin value.
Normal haemoglobin level varies according to age, sex, physiological condition, and health status.

Step 2: Adult male range.
In adult males, the normal haemoglobin level is generally around \(13\) to \(17\) g/dL.

Step 3: Checking the options.
\(8-10\) g/dL is low and indicates anaemia.
\(10-12\) g/dL is also below the normal adult male range.
\(13-17\) g/dL is the normal adult male range.
\(18-22\) g/dL is higher than the usual normal range.

Step 4: Final answer.
Therefore, the normal haemoglobin level in adult male is \(13-17\) g/dL. \[ \boxed{13-17\ \text{g/dL}} \]
