Quality of histologic specimen (n = 30)
| Quantity of tissue | |
| 0: sample with no material, n | 0 |
| Cytology (1‐2), n (%) | 2 (6.7%) |
| 1: sufficient material for limited cytologic interpretation but probably not representative, n | 1 |
| 2: sufficient material for adequate cytologic interpretation but insufficient for histologic information, n | 1 |
| Histology (3‐5), n (%) | 28 (93.3%) |
| 3: sufficient material for limited histologic interpretation, n | 8 |
| 4: sufficient material for adequate histologic interpretation but a low quality sample, na | 9 |
| 5: sufficient material for adequate histologic interpretation and a high quality sample, nb | 11 |
| Contamination | |
| 1: contamination present in >50% of the slide, n | 1 (3.3%) |
| 2: contamination present in 25‐50% of the slide, n | 3 (10.0%) |
| 3: contamination present in <25% of the slide, n | 26 (86.7%) |
| Amount of blood | |
| 1: significant, n | 10 (33.3%) |
| 2: moderate, n | 11 (36.7%) |
| 3: minimal, n | 9 (30.0%) |
a
Low quality sample, total material within a 10 power field in length.
b
High quality sample, total material more than a 10 power field in length.
