Please note: There is a supply chain issue with our culture media manufacturer. There is a national supply shortage of culture media materials. Due to this, results will unfortunately be delayed because we had to move to a 7 day methodology. We temporarily have to incubate all tests for 7 days once received. We will check these tests every day, and notify your office immediately if there is an issue with your test. We are unable to give you your official result until the 7 day incubation is complete.

Similar to previous national PPE issues, this should be resolved shortly, though the actual time of delay is unpredictable. We will strive to resolve as soon as our current supplier has our testing media available again. We apologize for the unavoidable and unpredictable inconvenience. Please feel free to contact us with any questions.

• Unlimited access to test results. Our website allows unlimited access to test results starting from 2008, including cultures received and in progress.
• All positive results are telephoned immediately. Retest strips are sent free of charge for all positive results.
• We use Gram Stain verification for all positive tests.
• Postage paid envelopes are provided for return of specimens.
• Tests are identified with bar codes to ensure accurate entry of client information and proper identification of each test.
• Consultation with faculty and staff available at no charge.
• Clients have the ability to go paperless. Offices can opt out of receiving routine culture reports by mail.
