Muhammad Faiz: Types of Hemoglobin and Their Functions

Muhammad Faiz, Shift Incharge and Biosafety Cooridinator at Chughtai Lab, shared a post on LinkedIn:

“Hemoglobin (Hb), Types of Hemoglobin and Their Functions

Your Hb report shows more than anemia. Each hemoglobin type explains how oxygen moves, how red cells work, and why some blood disorders develop.

What You Learn in This Post

1. HbA

  • Main adult hemoglobin
  • Carries oxygen in healthy adults

2. HbA₂

  • Minor adult hemoglobin
  • Important in thalassemia screening

3. HbF

  • Fetal hemoglobin in newborns
  • Higher oxygen affinity than HbA

4. Abnormal Hemoglobins

  • HbS linked with sickle cell disease
  • HbE and HbC linked with inherited blood disorders

Why Hb Testing Matters

  • Detects anemia
  • Helps diagnose hemoglobinopathies
  • Supports thalassemia screening
  • Evaluates oxygen-carrying capacity

Key Takeaway

Understanding Hb types helps you interpret CBC findings, anemia patterns, and abnormal red cell disorders more accurately.”
