ALT-70 Score for Cellulitis
Values below 18 years remain calculable to preserve the published arithmetic, but pediatric use remains outside the validated scope.
years
Tachycardia adds 1 point when heart rate is >=90 bpm.
bpm
Enter the white blood cell count with the matching unit. Leukocytosis adds 1 point at >=10 ×10^9/L or >=10000/µL.
Clinical noticeEducational diagnostic-support tool only. Use ALT-70 only within the validated adult lower-extremity cellulitis context and never as a stand-alone replacement for clinical assessment.
Context and use
ALT-70 = unilateral lower-extremity involvement (3) + leukocytosis (1) + heart rate >=90 bpm (1) + age >=70 years (2).
Published interpretation: 0-2 unlikely, 3-4 indeterminate, 5-7 likely for cellulitis.
