Defendant appeals his conviction for driving under the influence of intoxicants, arguing that evidence of a urine test was inadmissible because the test did not conform to the applicable protocol. See ORS 813.131(4) (1997). The state confesses error, and we agree. State v. Chipman, 176 Or App 284, 31 P3d 478 (2001).

Reversed and remanded.
