Question 1

What do I need to bring to my appointment?

Accepted Answer

All participants over the age of 18 must bring a valid, government-issued photo ID (such as a driver’s license, state ID, military ID or passport). Please contact us if you have questions about acceptable identification.

Question 2

Can a urine drug test be beaten or adulterated?

Accepted Answer

Weaver Lab takes all precautions to ensure we obtain a valid sample. We check the temperature of all samples that are collected. There Is no access to water in the bathrooms and a dye is used in the toilets to prevent donors from diluting their samples. With our specimen validity testing, we can ensure the integrity of the test by measuring pH, creatinine, and specific gravity (when indicated) and testing for adulterants that may be added to the urine specimen. Synthetic urine is probably the number one thing we run across. Simply because it is available almost anywhere. All invalid results are automatically tested twice to ensure accuracy.

Question 3

What training does a Weaver Drug Testing Lab collector receive prior to performing a urine drug test collection?

Accepted Answer

Each Weaver team member is thoroughly trained for the collection procedure, and has certifications for hair and nail collections, as well as DOT certifications. We have instructional procedure manuals as well as "mock" collections for urine, hair, nail and DOT designed to ensure proper training.

Question 4

Can random testing be performed on-site?

Accepted Answer

Yes. Weaver Lab will provide a staff collector on-site to perform drug testing collections. In some cases, an on-site collection fee will apply.

Question 5

How long is a positive sample available for testing?

Accepted Answer

Weaver Lab keeps all positive samples, and chain of custody for a period of one year. Samples are kept frozen.

Question 6

What testing methodology is used?

Accepted Answer

Weaver Drug Testing Lab utilizes the Olympus AU480 chemistry - immune analyzer, which produces over 800 tests per hour. We use gold standard products, like Syva Emit reagents and assays. Syva enzyme immunoassays for drugs of abuse are highly specific for the target drugs, reproducible, and demonstrate consistent lot-to-lot stability. We also utilize the DIMS Data Manager, which is specifically designed for the toxicology lab. It provides accurate, high throughput and tracking, streamlining the exchange, retrieval, and delivery of information to ensure timely, reliable decision making every step of the way. DIMS is fully integrated with outside laboratories, off-site facilities, treatment centers, and the criminal justice system, including drug courts, probation, and correctional facilities. DIMS has barcoding, for bi-directional instruments and chain of custody, with reflex testing and auto re-run of positives on an assay or panel basis.

Question 7

What is the turnaround time for negatives? Positives?

Accepted Answer

Once the lab has received the sample, negative results are reported on the same day, with some exceptions. Positive screens will require further testing that may take 3-5 business days. All positive results are confirmed by GC/MS at a SAMHSA certified lab and reviewed by our MRO (Medical review officer) Dr. Philip Lopez.

Question 8

What is the process for MRO on positive results?

Accepted Answer

If a positive is confirmed by GC/MS, the results are forwarded to the Medical Review Officer. The MRO contacts the donor by phone number provided on COC. The MRO will verify prescription medications with donors and pharmacy. The MRO will then determine the outcome of results to be positive or negative, or in some cases a safety risk. If the MRO is unable to contact the donor within 3 days, the results will be released as positive. Illegal substances will be turned- out positive after notifying the donor. The MRO will not consider or investigate a donor's claim that they are in possession of a valid medical marijuana license.
