Erythrocyte sedimentation rate (ESR)
Coloured Multi White Boy's Tm Team Tempo Nike WS Black Team White Shorts Team  

The ESR is a simple non-specific screening test that indirectly measures the presence of inflammation in the body. It reflects the tendency of red blood cells to settle more rapidly in the face of some disease states, usually because of increases in plasma fibrinogen, immunoglobulins, and other acute-phase reaction proteins. Changes in red cell shape or numbers may also affect the ESR.

Method

Shorts Coloured Multi White Team Boy's Team Black White WS Nike Tempo Team Tm When anticoagulated whole blood is allowed to stand in a narrow vertical tube for a period of time, the RBCs – under the influence of gravity - settle out from the plasma. The rate at which they settle is measured as the number of millimeters of clear plasma present at the top of the column after one hour (mm/hr).

There are two main methods used to measure the ESR: the Westergren method and the Wintrobe Method. 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. 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. The distance of fall of erythrocytes, expressed as millimeters in 1 hour, is the ESR.
Wintrobe method:
The Wintrobe method is performed similarly except that the Wintrobe tube is smaller in diameter than the Westergren tube and only 100 mm long. EDTA anticoagulated blood without extra diluent is drawn into the tube, and the rate of fall of red blood cells is measured in millimeters after 1 hour.  The shorter column makes this method less sensitive than the Westergren method because the maximal possible abnormal value is lower. However, this method is more practical for demonstration purposes.

Theoretical considerations

Team Tm Boy's Coloured Black WS Team White Shorts Multi Team Tempo Nike White Tempo Coloured Team WS White White Nike Tm Team Multi Team Shorts Boy's Black The RBCs sediment because their density is greater than that of plasma; this is particularly so, when there is an alteration in the distribution of charges on the surface of the RBC (which normally keeps them separate form each other) resulting in their coming together to form large aggregates known as rouleaux.

Shorts White Tempo Multi Black Team WS Coloured Nike Team White Boy's Tm Team

Coloured Team Tempo Multi Nike Black WS Boy's Shorts Team Tm Team White White Rouleaux formation is determined largely by increased levels of plasma fibrinogen and globulins, and so the ESR reflects mainly changes in the plasma proteins that accompany acute and chronic infections, some tumors and degenerative diseases. In such situations, the ESR values are much greater than 20mm/hr. Note that the ESR denotes merely the presence of tissue damage or disease, but not its severity; it may be used to follow the progress of the diseased state, or monitor the effectiveness of treatment.

Some interferences which increase ESR:

  • increased level of fibrinogen, gamma globulins.

  • Nike Boy's Shorts White Tempo Coloured Team White WS Black Team Tm Team Multi technical factors: tilted ESR tube, high room temperature.

Some interferences which decrease ESR:

  • abnormally shaped RBC (sickle cells, spherocytosis).
  • technical factors: short ESR tubes, low room temperature, delay in test performance (>2 hours), clotted blood sample, excess anticoagulant, bubbles in tube.
Chronic inflammatory disease (collagen and vascular diseases) increases ESR.
Polycythemia decreases ESR.
