Terminology for reporting results
It is advisable to use diagnostic categories such as negative (benign), suspicious, positive (malignant) and non-diagnostic (unsatisfactory), followed by a description.
- Negative (benign) aspirate
- Positive (malignant) aspirate
- Suspicious aspirate
An increasingly used classification identifies five categories basically splitting the suspicious category into probably reactive (T3 – low risk of malignancy) and probably malignant (T4 – high risk).
The Thy classification adapted from that highlighted by the Royal College of Physicians.
