Kuwait Score Interpretation

 

-32 to -7 points:	Low risk of progression
-6 to 15 points:	Indeterminate risk of progression
16 to 22 points:	High risk of progression

 

 

 

Notes

• In this calculator, mcg is the abbreviation for micrograms.
• This calculator represents findings from the literature referenced below. It is important to understand that these findings may not be representative of the experience in your local healthcare system.

 
Equations used
 

KuwaitScore = AgeFactor + CRPFactor + ProcalcitoninFactor + LymphFactor + MonoFactor + AlbuminFactor

 

 

Calculation Details and Variables

• AgeFactor is assigned values by this ordered logic:
  • If Age ≥41 yr AgeFactor = 4
  • Else AgeFactor = 0.
• CRPFactor is assigned values by this ordered logic:
  • If CRP ≥7 mg/L CRPFactor = 2
  • Else CRPFactor = 0.
• ProcalcitoninFactor is assigned values by this ordered logic:
  • If Procalcitonin ≥0.05 ng/mL ProcalcitoninFactor = 16
  • Else ProcalcitoninFactor = 0.
• LymphFactor is assigned values by this ordered logic:
  • If Lymphocyte Percent ≥31.5 % LymphFactor = -9
  • Else LymphFactor = 0.
• MonoFactor is assigned values by this ordered logic:
  • If Monocyte Percent ≥9.2 % MonoFactor = -8
  • Else MonoFactor = 0.
• AlbuminFactor is assigned values by this ordered logic:
  • If Albumin ≥39.5 g/L AlbuminFactor = -15
  • Else AlbuminFactor = 0.
