LRINEC, laboratory risk indicator for necrotizing fasciitis; NF, necrotizing Fasciitis; WBC, white blood cell; CRP, c-reactive protein.

To change the creatinine from umol/L to mg/dL, use the formula mg/dL=88.4*umol/L.

To change glucose from mmol/l to mg/dL, use the formula mg/dL=0.055 mmol/L.

To change CPR from mg/dL to mg/L, use the formula mg/L=0.1* mg/dL.
