Can one test HPV through blood test from the arm? Or is it done via DNA vaginal swab test and Pap test only? Can any doctor answer please?

Need a swab. HPV is a host of different viruses. Everybody has some of them. They're not dangerous if you comply with routine screening and care for cervical cancer. Even if you had every one of the mean strains, it's not worth getting yourself worked up over. Be thankful for a health care system that despite all the dysfunctions won't let HPV kill or ruin you.
