Frequently Asked Questions

Here are some common questions asked by our clients and their patients…

General

What kind of testing does DRG provide?

Currently, we provide PCR based molecular testing specifically designed for the digestive system to determine the specific cause or causes of patient symptoms and their specific drug resistance.

Do you bill insurance?

Yes, we bill all valid commercial and government insurance plans in the US as long as the ordering clinician has the appropriate credentials to bill your insurance.  Valid physicians MUST be registered with Medicare in order for us to bill Medicare.

What if my insurance company does not pay or I have not met my deductible?

You will be billed the amount that your insurance carrier states is the patient responsibility.

For what issues might the stool testing be useful?

Almost all digestive related symptoms and/or conditions.

I am interested in purchasing a stool test. Do I speak with my own doctor or consult with someone at DRG?

You can have your Gastroenterologist or your family physician order the testing for you.  Please provide us with where you are located, so that we can determine which of our Field Consultants would best handle your physician’s account (these accounts are set up at no cost).  You can order and pay for the test yourself, but you would still need to have a physician review the results with you to determine what course of action is best in your case.  DRG does NOT provide treatment advice.

If I purchase the test directly from the lab, how will I get the results?

You can specify how you want the test to be delivered to you via link in email, USPS or sent to your doctor. Once your results are available, you will be notified based on what you selected in the TEST REQUEST FORM.

What type of samples do you use?
  •  Stool
  • Stomach tissue (obtained via upper endoscopy)(Future)
What bacteria, parasites, and fungi are identified by the testing?

The testing identifies the most frequently found pathogenic bacteria, as well as the most common parasites and fungi found in the gastrointestinal tract.  It also looks at specific digestive health markers to aid the physician in determining the best treatment strategy based on your specific results.  If a bacterium is identified as positive, and the ordering clinician has checked the appropriate box on the Test Request Form (TRF), then DRG also runs Antibiotic Resistance testing (future).

Will my medications affect the results of the test?

While you need to consult with your ordering physician/clinician with respect to any medications you are taking and follow their advice, we have generally found that there are no medications, prescribed, herbal, or otherwise, that affect the results generated by the tests at DRG.

Once the specimen is collected, how long before I have to send it to the lab?

You should send it the day you collect it.  If that is not possible, then as soon thereafter as you can.  However, significant delays have been shown to affect the validity of the results.

How long does the test take?

Normally 4-5 working days after it has been properly received at DRG Laboratory.  Missing or incomplete information can delay the process. Please be sure to include the following information so there is no delay in testing:

  • Patient and physician signature
  • Copy of insurance card
  • Correct test checked on the requisition
  • Name and date on the specimen tube and Requisition
What types of supplies are needed to retrieve the samples?

All of the items necessary to collect your stool sample, along with detailed instructions are provided, as well as shipping material to send it back to the lab.  Be sure to include your name and DOB on the specimen vial and your signature on the requisition along with a copy of your insurance card Review the following video for stool collection information.
