3. Transport of Blood Sample to TherapySelect
For the transfer of the blood sample the requisition form for the liquid biopsy has to be signed by the treating physician.
Afterwards the blood sample can be sent back to TherapySelect in a special kit (important: do not cool or freeze sample). The blood handling instructions can be found here: Guardant360® Blood Handling Instructions.
After arrival of the blood sample at TherapySelect it will be transferred immediately to Guardant Health for analysis.
4. Laboratory Testing and Analysis of Blood Sample
After the blood sample arrived in the laboratory of Guardant Health the laboratory testing is performed in order to detect present mutations by digital sequencing. The obtained data are evaluated carefully and the efficacy of associated targeted drugs and the level of ctDNA is determined.

5. Transmission of Test Report
The test report includes information about the present mutations of a patient as well as information about potential efficient therapy options and inefficient drugs for this patient. In addition it is reported if clinical trials for non-approved drugs are available. The level of ctDNA is also included in the test report.
The results are sent to TherapySelect and TherapySelect transfers the results to the treating physician.
6. Therapy Planning by Physician and Patient
The treating physician receives the Guardant360® test report to decide about the future therapy steps. It is possible for physicians and patients that TherapySelect explains the test report to them in the case of questions regarding the results.
The decision which therapy is applied is made together by physician and patient.
