I may be somewhat confused, but concerning HPV (OC strains 16, 18, etc..):

Is it correct that to confirm HPV as the likey cause of OC the primary tumor must be tested for the presence of HPV?

And

There is a blood test for HPV that will show if a person is infected (like as for HIV and EBV), but this alone is not confirmational of HPV associated OC?

Also

Can a secondary "lymph node" tumor be tested for the HPV association?

thanks
