Once the requisition form is completed: Sign and fax the completed form with a copy of the patient’s insurance information and pathology report to
866-712-5207. Castle will then initiate a benefits investigation and coordinate specimen acquisition with the appropriate lab. Patient results will be sent to the physician(s) indicated on the requisition form. Turnaround time is generally less than two weeks following receipt of the specimen from the pathology laboratory.

Specimen Type and Collection Process: The validated test is performed on esophageal adenocarcinoma tumor tissue obtained from formalin-fixed paraffin embedded (FFPE) specimens. Specimens are shipped at room temperature. We request 10 unstained slides of five microns thick and 1 H&E stained section with the tumor area clearly marked. Castle will incur the cost of shipping.
