MICROANATOMY

Detailed explanation-1: -Often, the first test used to diagnose anemia is a complete blood count (CBC). The CBC measures many parts of your blood. The test checks your hemoglobin and hematocrit (hee-MAT-oh-crit) levels. Hemoglobin is the iron-rich protein in red blood cells that carries oxygen to the body.

Detailed explanation-2: -Complete blood count (CBC). A CBC is used to count the number of blood cells in a sample of your blood. For anemia, your doctor will likely be interested in the levels of the red blood cells contained in your blood (hematocrit) and the hemoglobin in your blood.

Detailed explanation-3: -What is it used for? A hemoglobin test is often used to check for anemia, a condition in which your body has fewer red blood cells than normal. If you have anemia, the cells in your body don’t get all the oxygen they need. Hemoglobin tests are measured as part of a complete blood count (CBC).

Detailed explanation-4: -A hemoglobin test measures the volume of the protein hemoglobin found in your RBC. It is measured in grams per deciliter (g/dL) of blood or grams per liter (g/L) of blood. Hemoglobin is one component of RBC and gives these cells their distinct red color.
