Ohio Rev. Code § 3709.241: Minor may give consent for diagnosis or treatment of venereal disease.

Notwithstanding any other provision of law, a minor may give consent for the diagnosis or treatment of any sexually transmitted infection by a licensed physician, certified nurse-midwife, clinical nurse specialist, or certified nurse practitioner. Such consent is not subject to disaffirmance because of minority. The consent of the parent, parents, or guardian of a minor is not required for such diagnosis or treatment. The parent, parents, or guardian of a minor giving consent under this section are not liable for payment for any diagnostic or treatment service provided under this section without their consent.
