ORS § 109.259
Notwithstanding the objections of a party to an order that seeks to establish parentage, if the blood tests conducted under ORS 109.250 to 109.262 result in a cumulative paternity index of 99 or greater, the evidence of the blood tests together with the testimony of a parent is a sufficient basis upon which to presume paternity for establishing temporary support. Upon the motion of a party, the court shall enter a temporary order requiring the alleged father to provide support pending the determination of parentage by the court. In determining the amount of support, the court shall use the formula established under ORS 25.275.
