You should consult a lawyer before performing any tests. In Ohio, you are not required to answer any questions asked by a police officer. Ask to speak to a lawyer before answering any questions. If you are in doubt do not answer any questions until you have talked to a lawyer. Breath tests are not always accurate.
Several things can create false reading and the police have to follow specific procedures.
In Ohio, if those procedures are not followed and the test is challenged, the result may be inadmissible.
