The sedimentation rate-- or “sed rate,” for short -- is a blood test that checks for inflammation in your body. It’s one clue for your doctor that you might have a disease linked to ...
It appears that the sed rate is not a particularly reliable measure as it can be affected by a range of factors including the plasma viscosity (thickness or resistance to flow) of the blood where viscosity is negatively correlated with the sed rate (i.e. high viscosity gives a low or zero sed rate).
Low ESR, value below the normal range. An ESR value that is under the normal range does not bear any major significance but can be considered as an indication of conditions such as sickle cell anemia, polycythemia, protein irregularities and extreme leukocytosis. Conclusion
A normal or low sed rate effectively means you have very little inflammation in your body and rules out hidden cancer, active autoimmune disease and hidden infection for the most part. A low sed rate is a sign of health.
An erythrocyte sedimentation rate (ESR) test is sometimes called a sedimentation rate test or sed rate test. This blood test doesn’t diagnose one specific condition.
While a sed rate of 0 is not an average one for the general population, very low or zero ESR rates are not unusual in a person who has polycythemia. Note that the ESR is not a test which, in and of itself, necessarily indicates a specific diagnosis.
According to hfme.org, Hyde also mentions "hyper-gammaglobulinemia and hyper-fibrogenemia" as causing low ESR: "An unusually low sedimentation rate of 3 mm/hr is common in M.E. ESR rates as low as 0 have been documented in M.E. patients, and levels of 1 and 2 are very common.
The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells in whole blood descend in a standardized tube in a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation .
The sedimentation rate is also called the erythrocyte sedimentation rate because it is a measure of the speed that the red blood cells (erythrocytes) in a tube of blood fall to the bottom of the tube (form sediment). Sedimentation rate is often abbreviated as sed rate or ESR.
An erythrocyte sedimentation rate is a blood test usually done in combination with other blood tests. This lesson will discuss the causes of high and low erythrocyte sedimentation rate.
