What is cervical cancer?

According to the worldwide statistics,

a woman dies of cervical cancer in every minutes*
a woman is diagnosed with cervical cancer in every eight seconds#

According to HKCaR’s statistics, cervical cancer is fourth most common cancer in women worldwide. From 2018, cervical cancer has caused over 2.7%+ of female cancer deaths. Studies states that over 90-91% cervical cancer are infected by HPV *.

Test methods

More than 90-91% of cervical cancers are infected by HPV

The medical profession has confirmed that almost all cervical cancers (90-91%) are caused by persistent infection with Human Papillomavirus (HPV). Compared with low-risk HPV, persistent infection with high-risk HPV causes cervical cancers. The chance of causing cervical cancer is at least 30 times higher*. And 90% of cervical cancers are related to HPV 16, 18, 31, 33, 45, 52, 58 high-risk viruses.

HPV vaccine produces antibodies which develop immunity
HPV vaccine contains HPV virus capsid protein L1, which is the main antigen and does not cause disease or cancer
The vaccine can trigger the body to amalgate virus-like particles (VLP) to produce immune antibodies
The antibodies acts as protection and increase the immunity against the HPV virus when one may be exposed to in the future

Designed for people who are vaccinated against HPV

Scientific and accurate, measuring the level of antibodies in the blood

The latest HPV antibody test covers all antibodies of the nine-valent HPV vaccine, including HPV6, 11, 16, 18, 31, 33, 45, 52, 58 under the principle of antibody antigen-specific binding
According to the degree of antibody-antigen binding, you can accurately determine the level of 9 antibodies through quantitative experiments
Inoculate HPV vaccine within the time specified by the manufacturer, corresponding HPV antibodies will be detectable after vaccination to ensure adequate protection

Antibody level vary from person to person, double confirmation of vaccine efficiency

Different people have different levels of antibodies to HPV vaccine
Result being positive indicates the antibody level is strong enough for protection
HPV antibody test can test the effectiveness of the vaccine

Test Specifications

Test Code Methodology Specimen Requirements Turnaround Time

Frequently asked questions (FAQs)

A1 : After vaccination: You can test whether the vaccine is effective and to ensure adequate protection.
Vaccinated before: To detect whether the vaccine is still effective to provide protection.

A2 : Whether vaccinated with a 4-valent vaccine or a 9-valent vaccine, you can still take HPV9 antibody testing which can detect the antibodies within both vaccinations.

A3 : HPV vaccine for men can help prevent genital warts and anal cancer. Testing with antibodies will ensure that the vaccine is effective and that there is adequate antibody protection.

A4 : For patients who have been infected, certain levels of antibodies are produced in the body.
Studies have shown that patients who have been infected will have a booster response to the vaccine with at least 10 times more antibodies than before the vaccine.
