Back to Mining in Canada From Rocks and Minerals in Canada, Spring 1983 By Tom Jewiss Often, if not always, when the mining history of the Sudbury region is considered, 1883 is treated as the starting date.
The erythrocyte sedimentation rate (ESR) determination is a commonly performed laboratory test with a time-honored role. However, the usefulness of this test has decreased as new methods of evaluating disease have been developed.
The erythrocyte sedimentation rate (ESR), also called a sedimentation rate or Westergren ESR, is the rate at which red blood cells sediment in a period of one hour. It is a co â¦ mmon hematology test, and is a non-specific measure of inflammation.he normal sedimentation rate (Westergren method) for males is 0-15 millimeters per hour, and for females is 0-20 millimeters per hour. The sedimentation rate can be slightly more elevated in the elderly and is much lower for children.
