How do you do the Westergren method?

How do you do the Westergren method?

Westergren method: The Westergren method requires collecting 2 ml of venous blood into a tube containing 0 . 5 ml of sodium citrate. It should be stored no longer than 2 hours at room temperature or 6 hours at 4 °C. The blood is drawn into a Westergren-Katz tube to the 200 mm mark.

How do you read ESR in Westergren tube?

Procedure for ESR estimation: Fill the westergren tube up to mark 0 and place in the rack at room temperature undisturbed and away from sunlight. Take the reading exactly after 1 hour. Record in millimeters from top surface of column to top of RBC sediments.

How do you read sedimentation rate?

Results from your sed rate test will be reported in the distance in millimeters (mm) that red blood cells have descended in one hour (hr). The normal range is 0 to 22 mm/hr for men and 0 to 29 mm/hr for women. The upper threshold for a normal sed rate value may vary somewhat from one medical practice to another.

What Modified Westergren?

The Westergren method uses citrate, a liquid-based anticoagulant, resulting in dilution of blood, inaccuracies of which significantly affect the ESR. Modifications of the reference method, also called the modified Westergren method, are also widely used and use EDTA in place of citrate as an anticoagulant.

What is ESR analysis?

An erythrocyte sedimentation rate (ESR) is a type of blood test that measures how quickly erythrocytes (red blood cells) settle at the bottom of a test tube that contains a blood sample. Normally, red blood cells settle relatively slowly. A faster-than-normal rate may indicate inflammation in the body.

What is a normal ESR?

The normal range is 0 to 22 mm/hr for men and 0 to 29 mm/hr for women. The upper threshold for a normal sed rate value may vary somewhat from one medical practice to another.

What is ESR explain in detail?

The distance red blood cells travel in one hour in a sample of blood as they settle to the bottom of a test tube. The sedimentation rate is increased in inflammation, infection, cancer, rheumatic diseases, and diseases of the blood and bone marrow. Also called erythrocyte sedimentation rate and sedimentation rate.

What is the difference between the Westergren and Westergren methods?

Each method produces slightly different results. Most laboratories use the Westergren method. Westergren method: The Westergren method requires collecting 2 ml of venous blood into a tube containing 0 .5 ml of sodium citrate. It should be stored no longer than 2 hours at room temperature or 6 hours at 4 °C.

What does Westergren blood test results mean?

Westergren Blood Test Results Explained. The Westergren blood test is used to detect general inflammation that is occurring within the body. It measures the erthrocyte sedimentation rate and is a simple, common test that is ordered.

How is the Westergren-Katz test performed?

The blood is drawn into a Westergren-Katz tube to the 200 mm mark. The tube is placed in a rack in a strictly vertical position for 1 hour at room temperature, at which time the distance from the lowest point of the surface meniscus to the upper limit of the red cell sediment is measured.

Is modmodified Westergren method the best for Measuring ESR?

Modified Westergren method was considered as the reference method. The gold standard technique for measuring ESR is the Westergren method. However, it is an absolute necessity to validate these instruments against the standard Westergren method to enable routine use and also to substitute the standard ESR method.
