Hello and welcome to e health forum.
There are no blood tests for HPV, but there are specific blood tests (serology tests) that may show a person has had a HPV infection in the past, but the test cannot determine if HPV is currently present.
Women above the age of 30, in a monogamous relationship, usually have a low risk of HPV infection, and can consult their doctor, who can reduce the interval of testing for HPV, from annually, to once in 3 years.
Testing frequently , is needed when a woman,
- Starts having sex before age 18
- Has many sex partners
- Has sex partners who have other sex partners
- Has or has had a STI
The only women who do not need regular Pap tests are:
1. Women over age 65 who have had 3 normal Pap tests and in a row and no abnormal test results in the last 10 years, and have been told by their doctors that they don't need to be tested anymore.
2. Women who do not have a cervix and are at low risk for cervical cancer.
Pap smear screening is still recommended for those who have been vaccinated against HPV, since the vaccines do not cover all of the HPV types that can cause cervical cancer. Also, the vaccine does not protect against HPV exposure before vaccination.
I hope this information, helps to clear any persisting doubts.
