Blood chemistry tests showed diabetes patients had elevated whole blood leukocyte counts (median 16.3 × 109/L [interquartile range (IQR) 11.6–22.6 × 109/L]) and C-reactive protein was elevated (>8.0 mmol/L) in 169 of 173 episodes (98%; median 172 mg/L [IQR 71–298 mg/L]). This evidence concerns the gene CRP and diabetes mellitus.
