Hemoglobin Test

What is Hemoglobin?

• Function: Hemoglobin binds to oxygen in the lungs and carries it to tissues and organs throughout the body. It also helps transport carbon dioxide from the tissues back to the lungs for exhalation.
• Structure: Hemoglobin is composed of four protein chains (globins) and four heme groups, which contain iron molecules that bind to oxygen.

Why is Hemoglobin Important?

• Oxygen Transport: Ensures that all cells and tissues receive an adequate supply of oxygen for cellular functions and energy production.
• Carbon Dioxide Transport: Helps remove carbon dioxide, a waste product of metabolism, from the body.
• Maintaining pH Balance: Helps regulate the pH of the blood to ensure proper physiological function.

When Should You Get a Hemoglobin Test?

• Anemia: If you experience symptoms such as fatigue, weakness, pale skin, or shortness of breath, which may indicate low hemoglobin levels.
• Chronic Conditions: For monitoring conditions that affect hemoglobin levels, such as chronic kidney disease or nutritional deficiencies.
• Routine Checkups: As part of regular health screenings to assess overall health and detect any abnormalities.
