A case of Dettol addiction.

for serum ferritin estimation was taken either before dialysis or on a non-dialysis day into iron-free containers, and serum was stored at-20°C until assayed. Haemoglobin concentration was measured simultaneously. Serum aspartate transaminase concentration measured by autoanalyser in all patients ranged from four to 57 IU/l; in only three patients did the concentration exceed 50 IU/l. Serum ferritin concentration was measured by radio-immunoassay on all samples as a single batch.3 The normal range using this method is 15-250 Htg/l. Serum ferritin concentration is normally distributed on a logarithmic scale. Statistical analysis by Student's t test was therefore performed on logarithms, and geometric means are quoted.
