Testing Technique Measures The Rate Of Sedimentation Blood

In the diagnostic tests for parasitic diseases, there is a test to measure the rate of sedimentation blood, which helps support the diagnosis of parasitic infection. Does the patient have acute inflammation and also looks for inflammatory diseases of other causes.
There are two methods of measuring the rate of sedimentation
Pachenkow method.
Westergreen method.
At the laboratory, Anh Nga International Clinic selects the most popular Westergreen method today to perform the test

.
We will explore this method in depth.
1. WESTERGEEN METHOD
a Rule
Whole blood was diluted with physiological saline (NaCL 085%) and placed in a graduated glass ampoule. Leave the tube in an upright position, after a while the red blood cells will settle down, leaving the plasma layer on top.



.
The rate of erythrocyte sedimentation is the height of the plasma column formed when red blood cells have settled after an interval of 1 hour and 2 hours.
b. Tools and reagents.
Device for venous blood collection
Westergreen clarifier
Tube rack
Clock, test tube dry clean.
Physiological saline solution
2ml blood vein specimen collected in EDTA tube
c. Technical process.
Use Westergreen sediment tube to suck 50 mm of 0.85% physiological saline solution into a clean dry test tube.



.
Use a sediment tube to drain 200mm of venous blood to zero. Wipe the blood outside the tube.
Insert blood into test tubes with 0.85% NaCL
Mix the solution in a test tube several times.
Use a Westergreen straw to suction 200 mm of suction mixture to the zero line. Wipe the blood around the tube.
Plug in the stand upright.
Read the results over 2 times, the first time is 1 hour and the next time is 2 hours, based on the height of the plasma column.

. DISCUSSION
The rate of blood sedimentation is a non-specific test, it changes or increases in many physiological as well as patient's pathologies. Therefore this method is not meant to identify patients However, it is very important in monitoring the development of some diseases.
The rate of blood sedimentation increases in all types of diseases with inflammatory reactions or degenerated tissue, purulent proliferation and necrosis.
Sedimentation rate is useful for monitoring tuberculosis, rheumatoid arthritis and chronic infections.
Normally, the rate of blood sedimentation in women is higher than in men. During pregnancy, the rate of blood sedimentation increases gradually during the first 3 months and returns to normal after birth.
3. PRECAUTIONS TO BE CAREFULLY IN THE TESTING PROCESS
The tube is chipped or still wet and dirty.
Multiple anticoagulants with the ratio of blood or physiological saline phase to the wrong concentration.




The dilution rate is incorrect.
Shake the blood unevenly.
Blood for too long. The rate of sedimentation should be performed within the first 2 hours after the blood is drawn.
If the test is performed at a high temperature, the rate of sedimentation will increase.

According to Dr. Doctor, Director of Anh Nga International Clinic, Specialist in internal parasite Toxocara Toxocara can be infected mainly by people from soil environment, or from soil contaminated with herbivores, vegetables, ..



.. people who eat raw vegetables, chicken, rabbits, sheep, beef, Beef liver is at risk of infection. Toxocara larvae infect the bloodstream causing skin rashes similar to dermatological diseases, so it is difficult to diagnose if the doctor is inexperienced. Most patients who are interested in dog flukes treatment drugs do not believe in the treatment process, whether they have been completely treated or not. Dr. Anh said that everyone should see an experienced doctor to treat dog flukes Do not arbitrarily buy dog flukes medicines to drink, which will lead to drug resistance and damage to the liver..
