There is no HPV blood test currently available that can detect the presence of the virus directly. However, there is a blood test that can detect antibodies to certain strains of HPV.

This test, called the HPV serology test, can be used to determine whether an individual has been exposed to certain types of HPV in the past. The test works by detecting the presence of antibodies in the blood that are specific to certain strains of HPV.

The HPV serology test is typically not used as a screening test for HPV, as it cannot detect the presence of the virus directly and may not be able to identify all cases of HPV. Rather, it is used in specific situations, such as to confirm a diagnosis of genital warts or to evaluate individuals with abnormal Pap smear results.

It is important to note that while the HPV serology test can help to determine whether an individual has been exposed to certain strains of HPV, it cannot predict whether an individual will develop HPV-related health problems, such as cervical cancer. Regular Pap smears and HPV testing of cervical cells are still recommended as the primary screening method for HPV-related health problems.
