Worked example

15.1 mmol/L (middle of the reference range) = 171 mg/dL

Conversion formulas

mg/dL	mg/dL = mmol/L × 11.31	mmol/L = mg/dL × 0.0884
µmol/L	µmol/L = mmol/L × 1000	mmol/L = µmol/L × 0.001
g/dL	g/dL = mmol/L × 0.01131	mmol/L = g/dL × 88.4
g/L	g/L = mmol/L × 0.1131	mmol/L = g/L × 8.84
mg/L	mg/L = mmol/L × 113.1	mmol/L = mg/L × 0.00884
