What is ESR blood draw?

Erythrocyte sedimentation rate (ESR or sed rate) is a test that indirectly measures the degree of inflammation present in the body. The test actually measures the rate of fall (sedimentation) of erythrocytes (red blood cells) in a sample of blood that has been placed into a tall, thin, vertical tube.

What diseases cause high ESR?

  • Infection.
  • Rheumatoid arthritis.
  • Rheumatic fever.

The ESR is decreased in polycythemia, hyperviscosity, sickle cell anemia, leukemia, chronic fatigue syndrome, low plasma protein (due to liver or kidney disease) and congestive heart failure.

Why is ESR different in male and female?

PIP: In healthy subjects, the erythrocyte sedimentation rate (ESR) is higher in women than in men, and in both sexes, a rise occurs with age. It is well-established that pathological elevation of the ESR may be due to elevation of the fibrinogen level.

Why is ESR high in inflammation?

The ESR rate increases as a result of any cause or focus of inflammation. When an inflammatory process is present, fibrinogen enters the blood in high amounts and causes red cells to stick to each other, which raises the ESR. Moderate elevations are common in active inflammatory diseases.
