Microscopic evaluation scheme of acute inflammation

Neutrophil Severity
 Grade 0 Scattered individual cells may be present in the wound but primarily intravascular/margin-ating or widely spaced within the wound
 Grade 1 Viable/nondegenerate neutrophils as individual cells within the wound. If suppuration is present it does not coat the surface or span the length of the segment being graded
 Grade 2 Variably thick suppurative inflammation that spans the length of the segment
 Grade 3 Dense consistent thickness of suppurative inflammation that spans the length of the segment and neutrophils present within the wound bed below are in small clusters or individual
 Grade 4 Large pools of suppurative exudate over the length of the segment with large numbers present in the underlying wound bed, mostly present in clusters. Abscess formation.
Eosinophil Severity Scored based on the number of foci of clustered eosinophils or numerous individual cells, when viewed at 10×.
 Grade 0 Less than 10 foci
 Grade 1 11–20 foci
 Grade 2 21 to 30 foci
 Grade 3 31 to 40 foci
 Grade 4 >40 foci
