Hb (Hemoglobin)

Hemoglobin (Hb) is an iron-rich protein and an essential constituent of red blood cells (RBCs). It is responsible for the unique red color of RBCs. It plays a crucial role in carrying oxygen from the lungs to the body's tissues and transporting carbon dioxide back to the lungs. A Hb test helps assess overall health and detect various medical conditions, such as anemia, polycythemia, and other blood disorders.

Your doctor may suggest an Hb (Hemoglobin) test when you show symptoms of abnormal Hb levels, such as fatigue, weakness, pale skin, shortness of breath, dizziness, and rapid heartbeat. It also detects other health conditions like long-term infections, blood cell disorders, malnutrition, etc. Individuals with a history of anemia, blood disorders, or chronic medical conditions may undergo the Hb test as part of ongoing monitoring and management.

No special preparation is needed before this test; eat or drink as per your daily routine. Abnormal hemoglobin levels can indicate anemia (low Hb), polycythemia (high Hb), or other conditions affecting red blood cell production or function. Several factors like age, gender, pregnancy, and diurnal variations are to be considered while interpreting the test results.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. The results will help them determine your medical condition, make recommendations for lifestyle modifications such as diet and exercise, decide whether or not medication will be required to manage your condition, and formulate your overall treatment plan.
