The sedimentation rate as a prognostic help in acute otologic conditions has received scant attention. Only one article has come to my attention,1 and this dealt with only four cases.
There is some confusion in the use of the test because of varied technics. The same interpretation applies regardless of method, i. e., the rate is greatly accelerated in acute infections.
The technic used in cases here reported follows:
Blood was collected in either centrifuge tubes or syringes, and 2 cc. was transferred to large test tubes containing 0.5 cc. of 5 per cent sodium citrate. One cubic centimeter of this citrated blood was transferred to a Linzenmeier sedimentation rate tube 6.5 mm. long with a 0.5 mm. bore graduated to contain 1 cc. of citrated blood. The 1 cc. graduation is divided into divisions at 6, 12, 18 and 24 mm. Readings were taken at 6,
