Our proprietary digital sequencing technology lets us identify the signal of your patient's individual genomic alterations from the noise of interfering data that is inherent to standard next-generation sequencing techniques.

Common Questions

What are genomic alterations and why are they important to cancer?

Genomic alterations are changes that occur within the DNA of cancer cells. Some of these changes accelerate the growth of cancer. Some respond well to specific therapies. With a clear picture of the genomic alterations in your tumor, your doctor may be able to recommend a targeted therapy. In general, targeted therapies have fewer side effects than broad-based chemotherapy. They can also be more selective in stopping the spread of a cancer when other treatments have failed.

How can knowing my cancer's genomic alterations help my treatment?

Some genomic alterations are known to respond better to specific therapies. Guardant360 looks for all these clinically relevant alterations, giving your doctor the opportunity to tailor treatment to your individual cancer.

How quickly can I expect test results?

We provide results within 2 weeks of receiving your blood sample.

Does it matter what type of cancer I have or how advanced my cancer is?

Yes. Guardant360 is only indicated for advanced solid tumors. It does not test for hematological cancers like leukemia, nor early stage disease.

Does Guardant360 predict response to chemotherapy? Can it tell me how my cancer will progress?

Today Guardant360 does not predict chemotherapy response, but it does provide information on the genomic alterations known to respond to specific targeted therapies. As cancer research progresses, new response profiles may be identified.
