HPV collection kits are widely used in HPV detection. The following are their advantages, disadvantages, and limitations:

Advantages

• Simple Operation
  HPV collection kits usually contain specially designed collection tools, such as cervical brushes and sampling swabs. Medical staff can master the operation skillfully after simple training. They can collect the required samples quickly and conveniently without the need for complex techniques and equipment. The collection can be carried out in a routine gynecological examination or outpatient setting.
• Non – invasive or Minimally Invasive
  Most HPV collection methods are non – invasive or minimally invasive. Taking cervical HPV collection as an example, using a cervical brush or swab to gently rotate at the cervical os to collect cells causes minimal trauma to the examinee. The pain and discomfort are relatively mild, making it easy for the examinee to accept, and it will not cause obvious adverse effects on the reproductive system.
• High Detection Accuracy
  When combined with advanced detection techniques such as polymerase chain reaction (PCR) and hybrid capture assay, HPV collection kits can accurately detect the presence of HPV in samples and distinguish different HPV genotypes, providing a reliable basis for disease diagnosis and risk assessment.
• Good Repeatability
  When conducting HPV tests at different times or in different medical institutions, as long as the operation is carried out in accordance with the specifications, HPV collection kits can collect samples of reliable quality, ensuring that the test results have good repeatability. This is beneficial for the dynamic monitoring and comparative analysis of the patient’s condition.
• Wide Range of Applications
  HPV collection kits can be used not only for cervical cancer screening but also for the detection of HPV infections in multiple sites such as the anus, penis, vulva, vagina, and oral cavity. They meet the needs of different populations and various clinical requirements, helping to detect a variety of HPV – related diseases at an early stage.

Disadvantages

• Sampling Errors May Occur
  During the collection process, if the medical staff do not operate in a standardized manner, such as inaccurate sampling sites, improper sampling force, or insufficient amount of collected cells, the collected samples may not truly reflect the examinee’s HPV infection status, resulting in false – negative or false – positive results.
• Affected by Sample Preservation and Transportation
  The samples collected for HPV need to be preserved and transported under specific conditions, such as low temperature and moisture – retention. If the preservation and transportation do not meet the requirements, the viral nucleic acid in the samples may degrade or the activity may change, affecting the accuracy of the test results.
• Uncertainty of Test Results
  Even if the test result is positive, it cannot be determined that the examinee will definitely develop related diseases. This is because most HPV infections are temporary, and the body’s immune system may clear the virus on its own. In addition, a negative test result does not completely rule out the possibility of HPV infection. There may be missed detections due to sampling errors or low viral loads.

Limitations

• Inability to Detect All HPV Genotypes
  Currently, the HPV collection kits and detection methods on the market can usually only detect some known HPV genotypes. With the continuous progress of research, new HPV genotypes are constantly being discovered. Therefore, there may be cases where some rare or new HPV genotypes cannot be detected.
• Inability to Judge the Degree of Lesions
  HPV collection kits can only detect the presence of HPV and the infected genotypes, but cannot directly determine the degree of lesions in the examinee, such as the grade of cervical intraepithelial lesions. For patients already infected with HPV, other examination methods, such as colposcopy and pathological biopsy, are needed to further evaluate the condition.
• Not Suitable for All Populations
  For some special populations, such as children and pregnant women, HPV collection may carry certain risks or difficulties, and careful operation and selection of appropriate collection methods are required. Moreover, for people with special conditions such as immunodeficiency and those receiving immunosuppressive therapy, the interpretation of HPV test results may be more complex, and multiple factors need to be considered comprehensively.
