What is an add-on test request?
An add-on test is a request to add additional testing to a previously tested patient’s sample.
Is a new patient sample required?
Depending on the sample requirement, a new sample may not be required. The add-on test will be performed on the patient’s sample in-house at Baylor Genetics.
May I add a test to an in-house prenatal sample?
We do allow test additions to in-house prenatal samples. All prenatal testing needs to be discussed with one of our genetic counselors prior to ordering. Please call 1.800.411.4363 to speak to a genetic counselor regarding your request.
What should be considered when requesting an add-on test?
- If the ordering physician has changed, please submit a new requisition form found on our Requisitions page and specify “in-house” as the specimen type.
- For Institutional Billing: Please note that the add-on test request MUST include a signature authorization from the party to be billed. Physicians, counselors, and medical professionals, please route your requests through your institutional Send-Out Department, which initially handled the patient sample. An add-on test CANNOT be properly billed if the institutional Send-out Department has not approved the test addition paperwork. For your convenience, use the Test Revision Authorization Form (TRAF).
