The HPV collection kit is widely used in HPV detection and other aspects. The following are its advantages, disadvantages, and limitations:

Advantages

• Simple Operation: Whether it is operated by medical staff or collected by the examinee themselves, the use of the HPV collection kit is relatively simple. Usually, only by following the instructions in the manual and gently wiping or scraping cell samples at a specific site with tools such as a collection brush can the collection be completed. It does not require complex technology or equipment and can be used in various scenarios such as outpatient clinics, medical check-up centers, and even at home.
• Non-invasive or Minimally Invasive: The collection process generally causes minimal trauma to the human body. Taking cervical HPV collection as an example, using a collection brush to collect cells at the cervical os causes extremely little damage to the female reproductive system compared to some traditional examination methods such as tissue biopsy. The acceptance rate of the examinees is relatively high, and it will not have a great impact on the examinees’ daily life and work.
• High Detection Accuracy: The HPV collection kit can effectively collect cell samples from the diseased site, providing high-quality specimens for subsequent laboratory testing. Combined with advanced detection technologies such as polymerase chain reaction (PCR) and hybrid capture assay, it can accurately detect the presence of HPV virus infection and determine the specific subtypes of HPV, which has high sensitivity and specificity for the screening and diagnosis of diseases such as cervical cancer.
• Suitable for Large-scale Application: It is suitable for large-scale population screening. Due to its simple operation and relatively low cost, it can detect the HPV infection status of a large number of people in a short period of time, helping to detect HPV-infected individuals in the population at an early stage and achieving early prevention and treatment of diseases. It is of great significance for the prevention and control of HPV-related diseases such as cervical cancer.

Disadvantages

• Sampling Error Exists: The collection process depends on the technology and experience of the operator. If the collection site is inaccurate, the amount of collected cells is insufficient, or the collected sample is contaminated, etc., it may lead to false negative or false positive test results. For example, during cervical sampling, if the collection brush is not fully inserted into the cervical canal, diseased cells may not be collected, resulting in a missed diagnosis of HPV infection.
• Test Results Affected by Multiple Factors: The distribution and load of the HPV virus in the human body may change with factors such as time and physiological status. Some examinees may be in the window period of HPV infection, during which the virus load is low, and the collection kit may not be able to detect the virus, resulting in a false negative result. In addition, situations such as inflammation and bleeding in the vagina may also affect the accuracy of the test results.
• Limited Effectiveness for Some Special Populations: For some women with anatomical abnormalities, difficult exposure of the cervical os, or severe vaginal stenosis, it may be difficult to obtain satisfactory samples using a conventional HPV collection kit, affecting the reliability of the test results.

Limitations

• Cannot Directly Diagnose Diseases: The HPV collection kit is only used to collect samples for detecting HPV infection. Although HPV infection is closely related to the occurrence of various malignant tumors, detecting HPV infection does not necessarily mean that there will be lesions or related diseases. It is also necessary to combine clinical symptoms, signs, and other examination results, such as cervical cytology examination and colposcopy examination, for comprehensive judgment. A disease diagnosis cannot be made solely based on the HPV test result.
• Cannot Detect All HPV Subtypes: Currently, the HPV collection kits and detection technologies on the market can usually only detect a part of the common HPV subtypes. There are many subtypes of the HPV virus, and there may be some rare subtypes that cannot be detected, posing a certain risk of missed detection.
• Cannot Evaluate the Degree of Lesions: The HPV collection kit can only detect whether there is HPV infection and the infected subtypes, and it cannot conduct an in-depth evaluation of the diseased tissues, such as the scope of the lesions, the degree of severity, and whether there is infiltration, etc. For the staging of the disease and the formulation of the treatment plan, further examinations, such as pathological biopsy, are still required.
