Below is a plain-language prep guide for the barbiturate screen and confirmation in Air Force Academy, CO, including sample type and timing basics. A barbiturate screen and confirmation checks a sample for barbiturate-class drugs, with any screen-positive result verified by a second, more specific method.
Barbiturate Screen and Confirmation: what it measures
The screen looks for barbiturate-class compounds in the sample, often reported as a positive or negative result against a cutoff. The confirmation step identifies and verifies the specific barbiturate present when the screen is reactive. Together they distinguish a presumptive screen finding from a confirmed one.

How to prepare for the Barbiturate Screen and Confirmation
In most cases no special preparation is required beyond normal hydration and following the collection site's instructions. Ask the lab about any timing or fasting guidance before you go.
- Confirm with the collection lab whether any fasting, timing, or hydration instructions apply to your visit.
- Drink normal amounts of water beforehand unless the lab tells you otherwise, since a very dilute sample may not be acceptable.
- Tell the collector about any prescription or over-the-counter medicines and supplements you take, as some can affect screening results.
- Bring a current list of your medications and your test order or requisition paperwork.
- Avoid guessing at cutoff times or collection windows on your own and verify them with the lab in advance.
Fasting, timing, sample type, and what to bring
Fasting
Fasting is usually not required for a barbiturate screen, but instructions can vary by laboratory and by test order, so confirm with your lab.
Best time to collect
There is typically no required time of day for collection, and most labs accept samples during their normal operating hours. If your clinician specified a collection window, follow that instead and verify it with the lab.
Sample type
Urine sample. The collector will explain the process before starting.
What to bring
- Your printed lab order or requisition form — the ordering physician prepares it for you after you order, and you print it (or fax it from your account) before visiting
- Your order confirmation email, in case the collection site asks to see it
- A government-issued photo ID (most collection sites verify identity at check-in)
- A written list of the medications and supplements you currently take
- A short-sleeved or loose-sleeved shirt for an easy blood draw
- Water to drink before the draw and a light snack for afterward, if your test requires fasting
You do not need an insurance card or a payment method at the collection site: the lab does not bill insurance, and you pay at order time, so there is no copay or deductible. The lab also provides the physician's requisition, so you do not need a separate doctor's referral.
Order process and what-to-bring details reflect the lab's published instructions, paraphrased in our own words. Confirm final requirements with the collection lab that will perform your draw.
The collection visit, step by step
You provide a urine sample at the collection site, usually in a private restroom, following any site-specific handling or chain-of-custody procedures. The sample is then screened, and if the screen is reactive it is sent on for confirmation testing.
Details worth confirming with the collection lab before your visit:
- Does this test require any fasting or specific timing before collection?
- What is the cutoff value used for the screen at your lab?
- How long will results take if confirmation testing is needed?
Why the Barbiturate Screen and Confirmation may be ordered
A clinician may order this testing to evaluate possible barbiturate exposure, to support a medication monitoring or compliance program, or as part of a broader drug panel. It can also be used when a specific barbiturate level needs to be verified rather than only screened.
Understanding your results
Reference ranges, cutoffs, and reporting formats differ between laboratories, so results should always be interpreted using the range printed on your own report. Turnaround is typically 1-3 business days, though confirmation testing can take longer if it is required.

Common questions
Frequently asked questions
Do I need to fast for a barbiturate screen?
Fasting is generally not required for this type of testing, but requirements can vary by laboratory and by how the test was ordered. Confirm the specifics with your collection lab before your visit.
What should I tell the collector before my sample is taken?
Share a complete list of prescription and over-the-counter medicines and supplements you use, since some substances can influence screening results. The collector can note this information with your sample.
Why would my sample need confirmation testing?
Screens are broad and can be reactive for reasons other than a true barbiturate, so a more specific method is used to verify a presumptive result. Confirmation is normally performed only when the screen is positive or flagged.
Will a dilute sample affect my results?
Very dilute samples may not be acceptable to the laboratory and could require a repeat collection. Follow the hydration guidance provided by your collection site to avoid this.
