Table 2 The scale used for evaluation of CD25, CD56, CD68, CD69, and CD16 antigens expression.
Antigen | Immunoreactivity | ||||
|---|---|---|---|---|---|
| Â | 0 | 1+ | 2+ | 3+ | 4+ |
CD25 | Lack of positive cells | Single positive cells | 1–5 positive cells/1 hpf | More than 5 positive cells/1 hpf | - |
CD56 | Lack of positive cells | Single positive cells | 1–5 positive cells/1 hpf | More than 5 positive cells/1 hpf | - |
CD69 | Lack of positive cells | Single positive cells | 1–5 positive cells/1 hpf | More than 5 positive cells/1 hpf | - |
CD68 | Lack of positive cells | 1–5 positive cells/1 hpf | 6–10 cells/1 hpf | 11–20 positive cells/1 hpf | More than 20 positive cells/1 hpf |
CD16 | Lack of positive cells | 1–5 positive cells per 1 hpf | 6–10 cells/1 hpf | 11–20 positive cells/1 hpf | More than 20 positive cells/1 hpf |
