TBS is an abbreviation for the Bassett Classification System, which is used clinically in obstetrics and gynecology, and is a diagnostic and diagnostic classification of female vaginal or cervical shed cells. During the examination, a brush or scraper is chosen to take the cells from the area of the junction of the columnar and squamous epithelium of the cervical opening, gently scrape the cells, smear them on a slide and then make a specimen for observation under a microscope, which helps to detect early cellular changes in the cervix and can screen patients for the presence of cervical cancer. The results of the TBS report should include general information about the patient, such as name, age, and medical history, as well as a detailed description of whether the patient has microbial infections such as bacteria and fungi, and whether there are abnormalities in the cells taken. It will also indicate whether normal cells have morphed into other abnormal cells, such as atypical squamous epithelial cells, low grade squamous intraepithelial lesions, high grade squamous intraepithelial lesions, etc. Some of the cancerous cells will also be shown, and if cells not originally belonging to the vagina or cervix are found, they need to be noted. When patients are given a TBS report, they need a professional to interpret the results and make a diagnosis of the disease.
