Blood Haemoglobin Analysis Meter is a medical device to test Haemoglobin in Human body or animals.Hemoglobin concentration is one of the routine blood tests, and its main clinical use is for the identification and diagnosis of anemia and erythropoietic disorders. The hemoglobin concentration is often parallel to the red blood cell count, and the clinical significance of the two is basically the same. In healthy people, the hemoglobin concentration is highest at 8:00 a.m. and lowest at 8:00 p.m.; it is higher in heavy smokers; and it is slightly lower in children, elderly and pregnant women.Hemoglobin measurement is a better indicator of the degree of anemia than red blood cell count. Once anemia is determined, further investigation of the cause is needed, such as iron deficiency, bone marrow disorders and diseases affecting the bone marrow, such as cancer, hereditary enzyme defects, acute and chronic blood loss, hemolytic diseases, etc.
