The use of non-invasive brush biopsies as an auxiliary tool in the diagnosis of oral mucosal lesions has gained renewed interest since improvements in cytological techniques such as the development of adjuvant diagnostic tools and liquid-based cell preparation techniques. Exfoliative cytological procedures, based on the sticky slide and detergent scrub techniques, were used in the nonintrusive collection of horny cells from the skin sur face of volunteers 20 to 30 yr of age and 65+ yr of age. These samples were analyzed with a variety of instru ments, including a Magiscan image analyzer, a Vickers The potential of Raman exfoliative cytology (REC) in identifying premalignant conditions was investigated. Oral exfoliated samples were collected from healthy volunteers ( n=20), healthy volunteers with tobacco habits ( n=20), and oral premalignant conditions ( n=27, OPL) using Cytobrush. Spectra were acquired using Raman microprobe. Blood Collection Blood was collected at 0930 hr after collection and anal-ysis of vaginal exfoliative cytological samples.

There are many reasons for obtaining a non-diagnostic sample: Poor cellularity of the sample: Due to a poorly exfoliating lesion or poor sample collection. Excessive blood contamination: This contributes leukocytes, which need to be differentiated from a true inflammatory infiltrate, which can be difficult. ex·fo·li·a·tive cy·tol·o·gy.

If this is the first exfoliative cytology test that shows atypical cells, then usually, which includes collection and examination of exfoliated cells such as vaginal scrapes, sputum, urine, body fluids etc. Collection of cells by brushing, scraping or abrasive techniques is usually employed to confirm or exclude malignancy. Fibreoptic endoscopes and other procedures can be used for collecting samples directly from the internal organs. • Collection Procedure:- Using standard paracentesis technique. A minimum of10 mL of specimen is desirable for optimal cytologicevaluation. Heparin may be added to the specimen toreduce clotting.- Place three (3) units of heparin per mL capacity ofthe collection container.

Methods of specimen collection. Individual cells may be studied in many ways. A. Exfoliative Cytology: It is the study of Exfoliative cytology: Impression smears: Useful in exudative skin lesions and preparation of cytology smears from biopsy specimens. Smears may yield only Exfoliative cytology is the microscopic examination of shed or desquamated cells from the epithelial surface usually the mucous membrane.

If it cannot be immediately delivered, add three units of heparin per mL of fluid to prevent clotting, and place in refrigerator until it can be delivered. For cytology of sediment, the sample is collected from the fixative that was used for processing the biopsy or autopsy specimen. The fixative is mixed properly and taken into a centrifuge tube and is centrifuged.
