Dear All
We have recently had considerable discussion concerning the number of
significant figures that should be used in reporting biochemistry results.
Many laboratories in Western Australia report serum creatinine results in
umol/L, while other parts of Australia report in mmol/L.
It has been suggested that if we are going to use umol/L units we should
only report to the nearest 10 umol/L. I am interested in how other labs
deal with this problem as we cannot find much in the literature except for a
letter by Badrick and Hickman in Ann Clin Biochem 2002;39:162.
If we adopt the argument in this letter how many significant figures should
be used to report glucose and urea results, for example.
