Several errors occurred in this paper by Douglas G Tincello and David H Richmond (7 February, pp 435-7). Three incorrect figures were cited from Etherington and James in the table: the sensitivity should have been 81.8%, and the positive and negative predictive values for all four tests in combination should have been 10.5% and 99.3% respectively. The third key message should have read “Commercially available reagent strips for testing urine do not perform to a sufficient standard.”
