Preparing for a Cocaine Metabolite Screen and Confirmation in Yamhill, OR starts with three questions: whether you need to fast, when to collect, and what to bring. This test screens for cocaine metabolites and confirms any screen-positive result.
What this test looks at
It measures the presence of cocaine metabolites, which are substances the body produces after cocaine use. The screen gives a preliminary result, and the confirmation identifies the specific metabolite to verify the finding.

- Benzoylecgonine
How to prepare for the Cocaine Metabolite Screen and Confirmation
Routine orders rarely require special preparation. The testing location can confirm any timing or fasting details when you book.
- Confirm with the lab whether any fasting is needed before collection.
- Ask the lab about the best time of day to provide the sample.
- Bring a valid photo ID and your test order paperwork.
- Tell the collector about any medications or supplements you take.
- Stay hydrated unless the lab tells you otherwise.
Fasting, timing, sample type, and what to bring
Fasting
Fasting is usually not required for this test, but requirements can vary by lab and order. Confirm with your lab.
Best time to collect
Collection can generally be done at any time the lab is open. Ask the lab whether a specific collection window is preferred for your order.
Sample type
Blood draw. 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.
What happens during the collection visit
A trained collector draws a blood sample from a vein in your arm, which usually takes only a few minutes. The sample is then sent to the lab for screening and, if needed, confirmation testing.
Details worth confirming with the collection lab before your visit:
- Does this order require fasting or a specific collection time?
- What is the expected turnaround time for screen and confirmation results?
- How will I receive my results and who should I contact with questions?
When this test is useful
A clinician may order this test to check for recent cocaine use as part of a drug screening panel. It may also be used in monitoring or employment-related testing programs where permitted.
Understanding your results
Reference ranges and cutoff values vary by lab, so results should be interpreted using the range provided by the testing lab. A positive screen is typically followed by confirmation testing before results are considered final.
Preparing in Yamhill
If you are preparing in Yamhill, plan around the lab's hours rather than the other way around, especially when a fasting window is involved.
General test information is compiled from publicly available reference material, including MedlinePlus (medlineplus.gov) and the Centers for Disease Control and Prevention (cdc.gov), and is reviewed for clarity. Preparation and what-to-bring details reflect the lab's published instructions, paraphrased into our own words. Preparation instructions, timing, and pricing vary by collection lab — always confirm them with the lab that will perform your draw.
