Endoscopic cytology or microbiology brushes are specialized brushes used during endoscopic procedures to collect cell and microbial samples from inside the body for diagnostic testing.
Some key points:
Cytology brushes have narrow, soft bristles designed to gently scrap mucosal surfaces without causing damage. This lifts superficial cell clusters for analysis.
Microbiology brushes often have stiffer bristles that can reach deeper layers and collect adequate microbiological specimens from tissue or secretions.
Both types of brushes have long, thin handles that allow them to be passed through the instrument channel of a flexible endoscope like during esophagogastroduodenoscopy (EGD) or bronchoscopy.
During the procedure, the endoscopist can directly visualize the target area and brush it under direct vision to collect cells/microbes.
Cytology samples are smeared onto slides for staining and microscopic examination to look for abnormal or malignant cells.
Microbiology samples are transported in preservative solution to the lab for culturing and identification of infectious organisms.
This enables non-invasive collection of diagnostic specimens from the esophagus, stomach, lungs, uterine cervix and other internal organs or lesions.
