Hemoglobin; (NHC)

The Hemoglobin (Hb) (NHC) test is a blood test that measures the amount of hemoglobin, an iron-rich protein found in red blood cells. Hemoglobin plays a vital role in transporting oxygen from the lungs to all parts of the body and carrying carbon dioxide back to the lungs for removal. This test is an important component of the Complete Blood Count (CBC) and is widely used to assess overall blood health and oxygen-carrying capacity.

The Hemoglobin (Hb) test is commonly recommended for individuals experiencing fatigue, weakness, dizziness, pale skin, shortness of breath, rapid heartbeat, or suspected blood disorders. It helps diagnose conditions such as anemia, polycythemia, nutritional deficiencies (especially iron deficiency), and chronic diseases that affect blood health. Low hemoglobin levels generally indicate anemia, while elevated levels may be associated with dehydration, polycythemia, or certain lung and heart conditions. The test is also useful for monitoring treatment response in patients receiving therapy for anemia or other blood-related disorders. Hemoglobin results should always be interpreted along with the patient’s symptoms, medical history, and additional laboratory investigations to ensure an accurate diagnosis and appropriate treatment. Early detection of abnormal hemoglobin levels supports timely medical care and promotes overall health and well-being.
