In the NeXT Dx test, sequencing is performed on samples taken from your tumor tissue and blood or saliva. 

Once your doctor places an order for the NeXT Dx test, Personalis will work with your hospital’s pathology department to obtain a sample of your tumor. We will also coordinate the collection of a blood or saliva sample (either at your doctor’s office or in your own home). Your samples will be sent to the Personalis Clinical Laboratory, where they will be processed and analyzed. A report will be sent back to your doctor who ordered your test. Your doctor will be in touch to review the results of your test with you.
