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 [...]
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 [...]
In this article we will discuss about:- 1. Mechanism of ESR 2. Determination of ESR 3. Factors 4. Significance. Mechanism of ESR (Erythrocyte Sedimentation Rate): ESR can be observed to take place in three stages: 1. A preliminary in which taken, at least few minutes to form roleaux (aggregation of cell occur). 2. Then the period in which sinking of [...]
