Challenging an Unconfirmed Urine Test in a District of Columbia DUI Case

Attorney Answer

Two things here pull in opposite directions, and you need both. The "medical purposes only" line on a hospital lab report does not automatically keep that result out of a District criminal case — but the missing confirmation test is a real problem for the government, and it matters most because of a mandatory jail term that turns on exactly which drug was present.

Start with what the charge actually requires. D.C. Code § 50-2206.11 makes it an offense to operate or be in physical control of a vehicle in the District while intoxicated, or while under the influence of alcohol or any drug or any combination of them. A separate, lesser offense — operating while impaired — sits at § 50-2206.14. Notice what is absent from both: neither requires a chemical test result. A chemical test is a way of proving the case, not an element of it.

That is why the first thing to be clear-eyed about is this. In *Karamychev v. District of Columbia*, 772 A.2d 806 (D.C. 2001), the driver refused chemical testing altogether and was convicted of DUI anyway, and the Court of Appeals affirmed. It held the evidence sufficient on the officer's observations and the roadside sobriety tests alone, restating the District's standard: a person is guilty if he is "to the slightest degree" less able to exercise the clear judgment and steady hand needed to handle an automobile safely, and the prosecution "need not prove any specific degree of intoxication." The court also confirmed that police officers may give lay opinion testimony that a driver appeared to be under the influence. *Karamychev* construed the predecessor DUI statute, before the 2013 recodification, but that is still how District courts describe the offense. So if you are hoping the lab problem ends the case by itself, it very likely will not.

Now the part that cuts your way — and it is the opposite of what you were told. The assumption that a hospital report stamped for medical use cannot be used in court is not District law. Section 50-2206.52c provides that the results of chemical testing of blood or urine "may be admissible as evidence in a criminal proceeding if the chemical testing was performed at a forensic laboratory, hospital, other equivalent medical facility, or at a laboratory contracted by a hospital or medical facility to perform chemical testing for specimens supplied by the hospital or equivalent medical facility." A hospital laboratory is expressly on that list. That disclaimer is a laboratory protecting itself about clinical interpretation; it is not a rule of evidence, and arguing the case as though it were is a losing position.

Where the missing confirmation test actually bites. Look at § 50-2206.13(a)(4). On a first offense, a 15-day mandatory-minimum term of incarceration must be imposed if the person's blood or urine contains a Schedule I chemical or controlled substance listed in § 48-902.04, phencyclidine, cocaine, methadone, morphine, or one of its active metabolites or analogs. A mandatory minimum under § 50-2206.01(11) is a term the court cannot suspend, and it turns on the identity of a particular substance. A clinical immunoassay screen of the kind hospitals run is a presumptive test — it flags a class of compounds and is well known to cross-react. Confirmation by a second, different analytical method is what turns "presumptively positive" into proof that a specific listed substance was present. Without that confirmation, the government has a far harder time supporting the finding that drives the mandatory minimum, whatever else it argues about impairment generally.

Two more provisions worth knowing. Under § 50-1904.02(a), after a DUI arrest a person is deemed to have consented to submitting two specimens for chemical testing, and the officer elects which type is collected; § 50-1904.02(c) lets you obtain an independent test from a medical professional of your own choosing, but says your failure or inability to obtain one does not keep the government's result out. And § 5-1419(a) makes the Chief Medical Examiner responsible for ensuring the accuracy of blood and urine testing for the District's impaired-driving program — a useful place to probe whether your specimen was ever inside that program at all, or was simply a treating hospital's draw that the government picked up afterward.

What you can do

1. Establish which document you actually have. A treating hospital's clinical chart is a different thing from a specimen collected under the implied-consent statute and tested for the District's program. Ask the hospital's medical records department for the complete record of that visit, including all laboratory results, and ask whether the draw was billed to you as a patient encounter or collected at law enforcement's request. 2. If a case has been filed, have your lawyer demand the full laboratory package rather than the one-page result — the analytical method, the cutoff levels, calibration and control data, the chain of custody, and whether any confirmatory testing was ordered or performed. 3. Ask specifically whether two specimens were collected, as § 50-1904.02(a) contemplates, and what became of the second one. 4. Ask whether the government intends to prove a substance listed in § 50-2206.13(a)(4). If it does, the missing confirmation is not a technicality — it is the difference between a mandatory jail term and none. 5. Preserve the observational evidence too. Request body-worn camera footage and any station video. Because the case can be proven on observation alone, what the officer saw and recorded matters as much as the lab. 6. Do not read silence as the case going away. Call the clerk of the Superior Court of the District of Columbia and ask whether anything has been filed against you and, if so, the next date.

⏱ Time limits apply. A District DUI arrest normally generates two separate tracks — the criminal case and a licensing consequence handled administratively — and they run on different clocks and different standards of proof. Go through every piece of paper you were handed and look for anything captioned as a notice or an order about your licence. If one is there, the window to respond is measured in days, not months, and it does not wait for the criminal case. Treat it as the most urgent document in the file and act on it the day you find it.
