ON-SITE SCREENING DEVICES—FREQUENTLY ASKED QUESTIONS
Q: What is the shelf life of the on-site screening devices?
A: The on-site screening devices have a shelf life of 24 months. The expiration date is indicated on each individual foil pouch and can be used up until
that date.
Q: How many on-site test devices come in a box?
A: There are 25 on-site test devices in each box.
Q: What is included in my supplies?
A: Every on-site test device comes with a collection container. A confirmation box is also included with every order in the event of a positive to be confirmed by our laboratory. A product training DVD is also available at your request.
Q: Do the results hold up in court?
A: The on-site device provides only a preliminary analytical test result. A more specific analytical method, preferably gas chromatography/mass spectrometry (GC/MS), must be used to obtain a confirmed analytical result. Any result, which is contested or used punitively, and especially, if taken to court, must be confirmed. To confirm by GC/MS, call Redwood Toxicology Laboratory at 877-444-0049.
Q: Do the screening devices need refrigeration?
A: No, as stated on the "Storage and Stability" section of the product insert, the test device should be stored at 2° to 30C° and will be effective until the expiration date.
Q: Are the on-site screening devices biohazardous?
A: No, the device itself is not biohazardous. Urine is not considered biohazardous unless it contains blood.
Q: Do you accept payment by credit card?
A: Yes. Redwood Toxicology Laboratory accepts: Visa, MasterCard or American Express.

Q: Can I photocopy the results for my files?
A: Yes, the Panel-Dip & RediCup devices may be photocopied upon completion of testing. This may be an important factor for some agencies when it is necessary to maintain chain of custody.
Q: Are there any cross-reactions?
A: Since screening methods, whether laboratory based or on-site, depend upon antibodies to react with specific drugs, reactions with unrelated
drugs can also occur. For this reason, a more specific alternate method such as GC/MS must be used in order to obtain a confirmed analytical result.
Our laboratory can provide a list of substances that may possibly produce false positive screening results.
