Hemoglobin

A hemoglobin test is a crucial diagnostic tool used to assess the levels of hemoglobin in the blood. Hemoglobin is a protein present in red blood cells and plays a pivotal role in transporting oxygen from the lungs to various tissues and organs in the body. Monitoring hemoglobin levels is essential as minor to major deviations from the normal range can cause various health conditions like anaemia, polycythemia, or other severe health hazards like organ damage.
