Question

ESR (erythrocyte sedimentation rate) helps in knowing

• A. Degree of disease.
• B. Erythrocyte count.
• C. Plasma volume.
• D. Percentage of hemoglobin.

Answer 1

The correct option is A Degree of disease.

ESR (erythrocyte sedimentation rate) is a non-specific screening test indicative of inflammation. In this test, anticoagulant blood is drawn into a tube of standardized dimensions and left in a vertical position for exactly one hour. After that period the point at which the red cells have separated and settled from the plasma is recorded by reading from the scale on the side of the tube. This test measures the distance that RBC's fall in a vertical tube over a given time period. ESR (erythrocyte sedimentation rate) is meant for knowing Degree of disease.

So, the correct answer is 'Degree of disease'.
