Introduction
Liquid-based DNA testing is usually used to examine cervical cancer cells and determine whether there are any lesions indicative of cervical cancer. Specifically, liquid-based DNA testing primarily involves analyzing DNA from blood, urine, or cells. To a certain extent, it can help clarify the cause of disease, assess associated risks, and determine the presence of genetic abnormalities.
Liquid-based DNA testing is typically used to examine cervical cancer cells and determine whether there are any pathological changes in the cervix. The detailed analysis is as follows:
Liquid-based DNA testing primarily involves detecting DNA from blood, urine, or cells. To a certain extent, it helps clarify the cause of disease, assess associated risks, and identify potential genetic defects. It is currently a commonly used clinical method for initial cytological screening of cervical cancer and also serves as a preventive measure against cervical cancer. The test is usually performed 3 to 5 days after menstruation ends, when there is no menstrual bleeding. Prior to testing, individuals should maintain good personal hygiene, frequently change and wash underwear, and prevent bacterial infections that could affect test results.
After the test, patients should get adequate rest, avoid excessive fatigue, and refrain from swimming and tub bathing. Even if test results are normal, patients are advised to have a follow-up examination approximately once a year. This allows for early detection and timely treatment, preventing delays in diagnosis and therapy that could harm overall health.
