Sedimentation Rate Definition & Normal Range

A sedimentation rate is common blood test that is used to detect and monitor inflammation in the body. The sedimentation rate is also called the erythrocyte sedimentation rate because it is a measure of the red blood cells (erythrocytes) sedimenting in a tube over a given period of time. Sedimentation rate is often abbreviated as "sed rate" or ESR.

Multiple cells are involved in the release of ...

What Causes Your SED Rate to Be High? | Reference.com

A doctor usually orders a sed rate test to determine the underlying cause of unexplained fevers, muscle problems, joint problems or other vague symptoms, notes MedlinePlus. Causes of a high sed rate include pregnancy, thyroid disease, kidney disease, anemia and certain types of cancer.

Sedimentation (water treatment) - Wikipedia

Sedimentation is a physical water treatment process using gravity to remove suspended solids from water. Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans. Settling basins are ponds constructed for the purpose of removing entrained solids by sedimentation.

Sedimentation Rate, Erythrocyte - Quest Diagnostics

Sedimentation Rate, Erythrocyte Coverage Indications, Limitations, and/or Medical Necessity The erythrocyte sedimentation rate (ESR) is a sensitive but nonspecific test that is frequently the earliest indicator of disease when other chemical or physical signs are normal. It is most often used as a gauge for determining the progress and ...

Sed rate (erythrocyte sedimentation rate) - Mayo Clinic

SEDIMENTATION AND ACCUMULATION RATES. To determine sedimentation rates, one must first generate an age-depth relationship. At a site with precisely determined paleomagnetic stratigraphy and with unambiguously identified chrons, accumulation rate uncertainties arise almost entirely from uncertainties in the ages of reversal boundaries.

AGE MODEL AND MASS ACCUMULATION RATES

Linear sedimentation rates (LSRs) were calculated for 1-m.y. time intervals, and corrected LSRs were computed to compensate for the growth rates inherent in the mcd scale. Dry density data were used to convert corrected LSRs to total mass accumulation rates (MARs). Carbonate concentration data were used to estimate carbonate MARs.
