Grading of different types of inflammatory cells, size of cell body, dendrites and morphology taken into account.
| Grading morphology | Size (approximately) (μm) |
|---|---|
| Type 1 | |
| a. Dendritic-like small | 25 |
| b. Dendritic-like medium | 40 |
| c. Dendritic-like large | 55 |
| Type 2 | |
| a. Cell bodies lacking dendrites small | 10 |
| b. Cell bodies lacking dendrites medium | 20 |
| c. Cell bodies lacking dendrites large | 40 |
Type 1 includes bright, branched structures while type 2 describes hyperreflective cell bodies lacking elongations.
