The following points highlight the top four indices of red blood cells. The indices are: 1. Mean Cell Volume 2. Increased MCV 3. Decreased MCV 4. Mean Cell Hemoglobin. 1. Mean Cell Volume (MCV): The mean cell volume indicates the volume of the "average" red cell in a sample. It is expressed in femtoliters (fl; 10-15 liters). Traditionally, MCV was [...]
In this article we will discuss about the determination of blood group. Blood type (also called blood group) is a classification of blood based on the presence or absence of inherited antigenic substances (antigens) on the surface of red blood cells. If the red blood cell had only "A" antigen on it, that blood was called type A. If the [...]
Whole blood is diluted with a 3% acetic acid solution, which hemolyzes mature erythrocytes and facilitates leukocyte counting. The standard dilution for leukocyte counts is 1:20. This dilution is prepared using the leukocyte Unopette system. The dilution is mixed well and incubated to permit lysis of the erythrocytes. Following the incubation period, the dilution is mounted on a hemocytometer. The [...]
