Ohio Rev. Code § 313.16
In counties where no coroner's laboratory has been established or where the coroner's laboratory does not have the equipment or personnel to follow the protocol established in rules adopted by the director of health under section 313.122 of the Revised Code, the coroner may request a coroner of a county in which such a laboratory is established or that has a laboratory able to follow the director's protocol to perform necessary laboratory examinations, the cost of which shall be no greater than the actual value of the services of technicians and the materials used in performing such examination. Money derived from the fees paid for these examinations shall be kept in a special fund, for the use of the coroner's laboratory, from which fund replacements can be made. Such funds shall be used to purchase necessary supplies and equipment for the laboratory and to pay any associated costs incurred in the administration of this section at the coroner's discretion.
