A Phencyclidine (PCP) Screen and Confirmation in Timberline-Fernwood, AZ is usually quick, and most of the work is in the preparation: timing, fasting, and a short checklist. This panel screens for and confirms the presence of phencyclidine (PCP) in a urine sample.
What the Phencyclidine (PCP) Screen and Confirmation measures
The screen detects the presence of phencyclidine or its metabolites in urine at a set cutoff level. If the screen is non-negative, the confirmation step identifies PCP more precisely to reduce false positives.

Fasting, timing, sample type, and what to bring
Fasting
Fasting is usually not required for this urine drug test, but requirements can vary by lab and test order. Confirm with your lab before your visit.
Best time to collect
A urine sample can generally be collected at any time of day. Follow the collection site's instructions on timing and sample handling.
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 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
- A government-issued photo ID (most collection sites verify identity at check-in)
- A written list of the medications and supplements you currently take
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.

Details worth confirming with the collection lab before your visit:
- Does this test require any fasting or timing instructions?
- What is the cutoff level used for the screen and confirmation?
- How and when will my results be reported to my clinician?
