How do I know which strain of HPV I have?
Your exam
- A Pap test can show signs of dysplasia or warts on the cervix or in the anus.
- A colposcopy may be done to assess dysplasia more closely.
- An acetowhite test makes HPV disease (dysplasia or warts) easier to see.
- An HPV DNA test can be used to help diagnose HPV infection and find out which strain of HPV you have.
Does HPV 16 and 18 ever go away?
The good news is that more than 90% of HPV 16 and 18 infections go away within 6 to18 months of initial exposure.
How do you know if HPV is gone?
Most strains of HPV go away permanently without treatment. Because of this, it isn’t uncommon to contract and clear the virus completely without ever knowing that you had it. HPV doesn’t always cause symptoms, so the only way to be sure of your status is through regular testing. HPV screening for men isn’t available.
