Cytology Brushings

Cellular Pathology Respiratory Cytology


PRINCIPLE OF EXAMINATION

Cytology brushings are performed primarily for the diagnosis and classification of benign and malignant tumours, but it can also be used to identify infection. The main brushing types received are taken from the bronchus, oesophagus and biliary duct.

Brushing sampling allows clinicians to sample areas that are prone to bleeding if biopsied. Brushings can be taken from the surface of a tumour visualised with a scope.

SPECIMEN preparation – IN CLINIC

Liquid based Cytology (LBC)

  1. Wash the brush in the PreservCyt solution immediately to ensure rapid fixation.
  2. Cut the head off the brush and leave in the vial.

NB: Green labelled PreservCyt solution vials can be obtained from Pathology stores (01392 402906)
