Under the heading "Normal Values", in the subsection "Adults", there is a serious contradiction between the formula for ESR and the table beneath it. According to the table, for a 90-year old man, the normal upper limit for ESR value is 19. But according to the formula, the normal upper limit is (90 + 0)/2 = 45.
It is true that one of these limits is a 98% confidence limit and the other is a 95% confidence limit. But it is difficult to imagine that both of these can be correct. The discrepancy is too large to be credible. Kruskal ( talk) 21:48, 16 September 2009 (UTC)
Previously the claim was "Therefore, ESR may be replaced with C-reactive protein measuring." I found one study where this was not the case and edited accordingly but wonder if there may be enough other examples of this being false to remove the claim entirely rather than weaken it as I did.
Where defining something of this nature, i.e., any quantifiable result of a medical test, it would be helpful to indicate the normal reference range for the item, e.g., < http://pathcuric1.swmed.edu/PathDemo/nrrt.htm>.
formulas people, there exist formulas to determine the sedimentation rate. Dude 19:32, 14 March 2006 (UTC)
Other than Westergren method, there is Wintrobe's tube method for estimation of ESR. Nothin has been mentioned about that.
There is no mention of corrected ESR..

RA IS NORMAL REPORTED BUT ESR IS HIGH LEVEL SO WHAT IS MEAN ? —Preceding unsigned comment added by 59.95.185.78 ( talk) 08:34, 9 July 2008 (UTC)
Should ESR be expected to routinely be high after surgery? Correctrix ( talk) 06:13, 17 August 2015 (UTC)
Erythrocytes stuck together have the same density as individual ones, as well as iron (and any ohter material) have the same density whether you take a small sample object or a big one. Rouleaux form is what affects sedimentation rate, not density. Differently formed objects drown at different speeds, and erythrocyte form makes it hard to drown. — Preceding unsigned comment added by 109.229.117.242 ( talk) 08:14, 23 October 2017 (UTC)
