Q: My doctor ordered some blood tests. Can I eat or drink before the test?
A: This is dependent upon the type of blood tests ordered. Your physician should tell you if the test(s) require fasting (no eating, drinking, gum chewing, etc.). If you are unsure, please contact your physician or ask our laboratory personnel.

Q: Where are you located? Can I go to any of your locations to have my tests done?

Q: What kind of specimen is collected for a drug (toxicology) test?
A: Urine is the most common specimen type because drugs are cleared out of the bloodstream primarily by the liver and kidneys and eliminated through urine.

Q: Do I have to have a doctor’s order to have lab tests done?
A: According to State and Federal Regulations, Tribal Diagnostics must receive an order from your physician/health care provider before any laboratory tests can be performed (with the exception of the self-administered Veri-5 Drug Testing Kit). Your physician/health care provider will give you a Tribal Diagnostics requisition (test order form) to show which tests he/she has ordered.

Q: Do I have to have a physician / health care provider’s approval to have a self-administered (i.e., Veri-5 Drug Testing Kit, etc.) run?
A: No physician order is necessary for a self-administered drug test such as the Veri-5 Drug Testing Kit. Simply follow the collection directions that come with the kit. Drop off the specimen at Tribal Diagnostics and you’ll be able to access your confidential results within three business days.

Q: Do I need to be a Tribal member to utilize your diagnostic services?
A: No, we work with both private practice physicians as well as Native tribes across the United States.
