Hemoglobin electrophoresis is a blood test that can detect different types of hemoglobin. The test can detect hemoglobin S, the form associated with sickle cell disease, as well as other abnormal types of hemoglobin, such as hemoglobin C. It can also be used to investigate thalassemias, which are disorders caused by defective hemoglobin production.
The newborn's blood is sampled through a heel-prick and is sent to a lab for testing. The baby must have been eating for a minimum of 24 hours before the heel-prick test can be done. Some states also require a second blood test to be done when the baby is two weeks old to ensure the results. [152]
A healthy human has 12 to 20 grams of hemoglobin in every 100 mL of blood. Hemoglobin is a metalloprotein, a chromoprotein, and globulin. In mammals, hemoglobin makes up about 96% of a red blood cell's dry weight (excluding water), and around 35% of the total weight (including water). [5]
A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).
Hence, people with recent blood loss, hemolytic anemia, or genetic differences in the hemoglobin molecule (hemoglobinopathy) such as sickle-cell disease and other conditions, as well as those who have donated blood recently, are not suitable for this test. [49] Due to glycated hemoglobin's variability (as shown in the table above), additional ...
A hemoglobin test measures the amount of hemoglobin in your blood. If a hemoglobin tests shows that a person's levels are below normal, it means they have a low red blood cell count, which is known as anemia. If the test shows higher levels than normal, it means they have hemoglobinemia. [citation needed] The normal range for hemoglobin is: For ...
