What is touch imprint cytology?
Touch imprint cytology (TIC) is a well known pathological technique, which is used to provide a rapid intraoperative diagnosis of the biopsied tissue. Used as an adjunct to frozen sections, the procedure involves taking ‘touch’ imprints of the sample on a glass slide, fixing with alcohol and staining with H&E stain.
What is imprint preparation?
Imprint is a touch preparation in which tissue is touched on the slide and it leaves behind its imprint in the form of cells on glass slide; studies are made after proper staining.
How do you imprint a cytology?
Imprint cytology is a well-recognised simple technique for preparing a surgical specimen for pathological assessment. The excised SLN is sent fresh to the pathologist who processes it immediately. The cut surfaces are pressed onto a glass slide, which is then fixed and stained.
What cytology is used for?
Cytology is the exam of a single cell type, as often found in fluid specimens. It’s mainly used to diagnose or screen for cancer. It’s also used to screen for fetal abnormalities, for pap smears, to diagnose infectious organisms, and in other screening and diagnostic areas.
What are touch imprints?
The touch imprints were made by the surgeon immediately after obtaining the incisional biopsy tissue from the lesion. Touch imprints were obtained by gently pressing the fresh unfixed tissue to clean glass slides. At least four imprint smears were made in each case, avoiding blood and mucus.
How many types of cytology are there?
What kinds of cytology are there? There are two main kinds, or branches, of cytology: exfoliative cytology and intervention cytology. Healthcare providers can use cytology tests for almost all areas of your body.
How do you imprint a smear?
Background: Imprint smear is simple and rapid technique for tissue diagnosis. Imprint is a touch preparation in which tissue is touched on the slide and it leaves behind its imprint in the form of cells on glass slide; studies are made after proper staining.
What is exfoliative cytology?
Exfoliative cytology is a non-invasive test that uses the Tzanck smear technique to identify disease by examining the structure of cells obtained from scraped samples.
What does abnormal cytology mean?
This can mean that not enough cells or the wrong types of cells were found in your urine sample. You may need to repeat the test. Negative. This means no cancer cells were identified in your urine sample. Atypical.
How is cytology done?
Scrape or brush cytology: This procedure involves scraping or brushing some cells from the organ or tissue that’s being tested. Some areas where doctors use scrape or brush cytology include the breathing tubes that lead to the lungs, cervix (for a Pap test), esophagus, mouth and stomach.
What is an example of cytology?
For example, a common example of diagnostic cytology is the evaluation of cervical smears (referred to as the Papanicolaou test or Pap smear). In order for cytologic evaluation to be carried out, the material to be examined is spread onto glass slides and stained.
