What is the Oncotech EDR Assay?
The Extreme Drug Resistance Assay (EDR) Assay is a laboratory test performed on a patient's
tumor cells. This lab test can determine the probability of a tumor's resistance to a specific
chemotherapy drug. If the tumor cells grow in the presence of very high concentrations of
chemotherapy drug, then the cancer cells are considered resistant to that drug.
How does the EDR Assay help the cancer patient?
Once the EDR testing is completed on a patient's tumor cells, a lab report is created which shows
the probability of resistance for each chemotherapy drug tested. Drugs that are shown to be in the
Extreme Drug Resistance range are evaluated by the patient's physician in order to determine the
best course of treatment. Often, this means preventing unnecessary patient exposure to toxic,
ineffective chemotherapy drugs.
Is the EDR Assay right for me?
Only your doctor can determine if the EDR assay or any of Oncotech's other cancer testing services
are right for you. Please ask your physician about Oncotech's Extreme Drug Resistance Assay and
prognostic and predictive marker services.
How much does it cost?
Oncotech bills insurance directly and does not balance bill the patient. Patients may be
responsible for co-payments or unmet deductible amounts where required by law or insurance
contract. Oncotech has negotiated reimbursement contracts with many of the country's leading
insurance carriers, including many managed care organizations. A Social Security Administrative
Law Judge has determined that Extreme Drug Resistance Assays are "part of the generally
accepted medical practice" and are "not experimental." Oncotech bills Medicare directly on an
accept assignment basis. Oncotech will assist patients in obtaining reimbursement and may
provide indigent coverage where appropriate.
How do I get these tests ordered for me?
Your physician can directly order Oncotech laboratory tests if he or she has determined that the
EDR Assay or other Oncotech cancer testing services are right for you. The physicians office can
call 1-800-ONCOTECH for requisition forms and specimen handling guidelines.
How long do results take?
Results for the EDR Assay are available in 7 days. Prognostic/predictive marker results are
available in 3 days. Other laboratory services vary depending on specific test ordered.
