Liquid-based cytology test

Because the traditional acid-fast staining method has a false negative rate of 2% to 50%, in addition to the eye fatigue and the lack of gradation of the smeared cells that affect the diagnosis, the acid-fast stain contains a large amount of blood cells, white blood cells, mucus and fallen necrotic tissue, which affects the accurate diagnosis. In order to solve the latter problem, cell engineering experts have recently introduced a new technology called liquid-based analytical cytometry. Most people don’t know what this new technology is.

What is liquid-based cytology test (TCT)?

Liquid-based cytology test TCT is used to check the possibility of cervical precancerous lesions. It can also distinguish the presence of candidal vaginitis, candidal vaginitis, bacterial vaginitis, and can also screen female secretions. After TCT examination, there will be mild inflammation, mild to moderate inflammation, moderate to severe inflammation and hyperplasia of atypical squamous epithelial cells. When such a result occurs, you can judge according to your own condition and what the next treatment method is. However, in clinical medicine, it is generally recommended to combine HPV testing with testing, so the accuracy can reach 98%. At the same time, the tests of the two can be more accurate in screening for cervical cancer, so if conditions permit, it is still necessary to conduct combined tests, which will be of greater help in screening the disease.

Common questions before cervical liquid-based cytology test

1. Do not have sexual intercourse 24 hours before the cervical liquid-based cytology test. If you have sex, after the liquid-based images are taken, there will be a lot of sperm on the surface, which may easily cover up the diseased cells and lead to misdiagnosis.

2. Before doing cervical liquid-based cytology testing, there is no need to clean the vagina 24 to 48 hours. During the treatment of vaginitis, some vaginal suppositories may be used, which should be stopped 24 to 48 hours before surgery, and no additional vaginal examinations are required.

3. Generally speaking, it is not recommended for female patients to undergo liquid-based cytology testing during their menstrual period.

The practical significance of liquid-based cytology

Liquid-based testing significantly enhances the quality of testing of cervical cell samples. Basic Pap test is often blurred due to the influence of blood, mucus, inflammation and other factors, resulting in test errors. In clinical trials, liquid-based testing of the number of cervical cell samples can significantly increase the detection rate of diseased cells and relatively reduce the frequency of repeated Pap tests, thereby reducing unnecessary worries for patients due to repeated tests.

The reduction of the basic Pap smear error will inevitably elevate the detection of early lesions to a new level and enable these patients with early lesions to receive earlier and more effective treatment.
