HbA1c & eAG • Corrected Sodium • Basal Energy Expenditure — Deep green, mobile-first, result-oriented
1) HbA1c Converter & Estimated Average Glucose (eAG)
Enter either IFCC (mmol/mol) or DCCT/NGSP (%) — results update live.
Results will appear here.
Info:
DCCT (%) = (IFCC [mmol/mol] / 10.93) + 2.152. eAG (mg/dL) = (28.7 × DCCT [%]) - 46.7. eAG (mmol/L) = mg/dL ÷ 18.
Reference: Nathan DM et al., Diabetes Care 2008.
2) Corrected Sodium for Hyperglycemia
Adjust measured serum sodium for high glucose (select correction method).
Results will appear here.
Note: Glucose must be converted to mmol/L when using the correction formula below.
Corrected sodium (mmol/L) = Measured sodium + correctionFactor × (Glucose_mmolL - 5.6).
Refs: Katz 1973; Hillier 1999.
3) Basal Energy Expenditure (BEE / BMR)
Calculate daily resting energy needs using Harris-Benedict or Mifflin-St Jeor.
Results will appear here.
Mifflin-St Jeor: BMR = (10 × weight kg) + (6.25 × height cm) - (5 × age) + S where S = 5 for males, -161 for females.
Harris-Benedict: classic sex-specific formula (see embedded code).
Results shown in kCal/day and kJ/day (kJ = kcal × 4.184).
