Black,
The tubes are specially used for determination of the erythrocyte sedimentation rate (ESR) by the Westergren's Method. The mixing ratio is 1 part citrate solution to 4 parts blood. ESR measurements refer to the Westergren method.
The westergren rack is a student physiology practical apparatus that holds the westergren tube and is used in the determination of erythrocyte sedimentation rate ESR.
The erythrocyte sedimentation rate (sed rate) blood test measures how quickly red blood cells (erythrocytes) settle in a test tube in one hour. The more red cells that settle to the bottom of the test tube within the hour, the higher the sed rate. The sedimentation rate indicates that there is inflammation somewhere in the system.
An Erythrocyte Sedimentation Rate measures how fast red blood cells fall to the bottom of a glass test tube. If any abnormal proteins are present in the blood then the cells will drop faster.
To perform An erythrocyte sedimentation rate (ESR), also called a sedimentation rate or Westergren ESR, is the rate at which red blood cells sediment in a period of one hour. anticoagulated blood is placed in an upright tube, known as a Westergren tube, and the rate at which the red blood cells fall is measured and reported in mm/h. It is a common hematology test, It is a simple glass tube with marking on the side to measure the layers formed when blood separates.

In the case of blood tests it stands for the erythrocyte sedimentation rate (ESR), also called a sedimentation rate or Biernacki Reaction, is the rate at which red blood cells precipitate in a period of 1 hour. It is a common hematology test which is a non-specific measure of inflammation. To perform the test, anticoagulated blood is placed in an upright tube, known as a Westergren tube, and the rate at which the red blood cells fall is measured and reported in mm/h. (source wikipedia)
erythrocytes sedimentation rate (ESR) Westergren methodAn ESR of 120 indicates that you have a problem with inflammation it does not however indicate what the cause of the inflammation is.A sedimentation rate is blood test that can detect and monitors inflammation in the body.It is a measurement of the red blood cells (erythrocytes) sedimenting in a tube over a given period of time. this test is referred to as an ESR.Red blood cells settle in the bottom of the test tube given time leaving leaving the blood serum visible above. The sedimentation rate is simply how far the top of the RBC layer has fallen (in millimeters) in one hour. The sedimentation rate increases with more inflammation.The normal sedimentation rate (Westergren method) for males is 0-15 millimeters per hour, and for females is 0-20 millimeters per hour. The sedimentation rate can be slightly more elevated in the elderly and is much lower for children.
What causes Erythrocyte sedimentation rates to be high?The erythrocyte sedimentation rate (ESR), also called a sedimentation rate is the rate at which red blood cells precipitate in a period of 1 hour. This indicates a degree of inflammation. The test is performed by putting anti-coagulated blood in an upright tube, called a Westergren tube. The rate at which the red blood cells settle to the bottom is measured and reported in mm/h (millimeters per hour).ESR is governed by the balance between pro-sedimentation factors, mainly fibrinogen, and those factors resisting sedimentation, i.e the negative charge of the erythrocytes (zeta potential). If there is an inflammatory process in action, there is a high proportion of fibrinogen in the blood and this results in red blood cells sticking to each other. The red cells form stacks called 'rouleaux' and these settle more quickly.ESR increases where there is inflammation. ESR also increases in pregnancy or rheumatoid arthritis.
he erythrocyte sedimentation rate (ESR), also called a sedimentation rate or Biernacki Reaction, is the rate at which red blood cells precipitate over a period of anhour. It is a test which is a measurement of inflammation. To perform the test, anti coagulated blood is placed in an upright tube, known as a Westergren tube, and the rate at which the red blood cells fall is measured and reported in mm/h. If you have a low rate in indicates that you have little or no inflammation in your body. A sed rate is non specific therefore it will not point to any particular condition.
