Analysis of sedimentation velocity
The analysis of sedimentation velocity is known as one of the laboratory tests that is used to detect the presence of any infections in the human body, as it is not a diagnostic test, but one of the good tests to monitor the stages of the development of inflammatory activity resulting from an autoimmune diseases such as rheumatism, Infection, or cancer, and the analysis of sedimentation speed is no longer a common analysis in the present age because there are many alternative analyzes that give more accurate results regarding inflammation in the body and the extent of development.
Mechanism of sedimentation velocity analysis
The analysis of sedimentation velocity depends on the examination of the sedimentation velocity within one hour in the distance that the red blood cells drop in the test tube, which is high and calibrated to indicate the ratio. The greater the distance of the drop, the higher the inflammation in the body. The cause of these infections produces abnormal proteins, Red blood cells form blocks, thus increasing the density of these balls, and depositing them more rapidly than individual pellets.
Method of sedimentation velocity analysis
The person performing the sedimentation analysis should not be fasting. However, the test should be performed in the laboratory. The technician will take a blood sample from the vein in the facility and measure the distance of the red blood cells within one hour.
Natural ratios for sedimentation velocity analysis
- Ratio in males: The normal ratio of sedimentation analysis in males under 50 years of age is less than 15 mm per hour, and adult males over 50 years of age should be less than 20 mm per hour.
- Percentage of females : The normal proportion of females under 50 years of age is less than 20 mm per hour, and females over 50 are 30 mm per hour.
- Percentage in children: The normal ratio of children up to puberty is between 3 mm and 13 mm per hour.
Factors Affecting Sedimentation Speed Analysis
- Anemia and iron deficiency anemia, leading to a false reduction in the speed of the deposition of red balls or the appearance of abnormalities in the form of red blood cells.
- Perform analysis during pregnancy, or menstrual cycle.
- Aging.
- Increased cholesterol, which results in increased analysis result to more than 20 mm per hour.
Treatment of the speed of blood deposition
The process of treatment of the speed of sedimentation in the blood determines the factor that led to this speed. First, the diseases that cause this speed must be treated.
