Quantitative insulin sensitivity check index (QUICKI)

• quantitative insulin sensitivity check index (QUICKI)
  
  
  • based on fasting glucose and insulin measurements
    
    
  • QUICKI is derived by calculating the inverse of the sum of the logarithmically expressed values of fasting insulin and glucose:
    
    
    • 1 /[log(fasting glucose) + log(fasting insulin)] . It measures insulin sensitivity, which is the inverse of insulin resistance
      
      
    • a value of less than 0.339 indicates insulin resistance
      
      
    • both HOMA-IR and QUICKI compensate for fasting hyperglycemia, and the results for the indices correlate reasonably well with the euglycemic clamp technique
