Galleri® Multi-Cancer Blood Test in Los Angeles

An advanced blood-based screening designed to detect cancer signals early—often before symptoms begin.

What Is the Galleri® Multi-Cancer Blood Test?

The Galleri® test is a revolutionary blood test that looks for cancer-related signals in your bloodstream. It is designed to detect signals associated with multiple types of cancer, including several that currently have no recommended routine screening tests.

This test does not diagnose cancer, but it can identify the presence of a cancer signal and help guide next steps for further evaluation.

How the Galleri® Test Works

The Galleri® test analyzes fragments of DNA circulating in the blood that may be shed by cancer cells. Using advanced molecular technology, the test can:

Detect cancer signals associated with many cancer types
Predict the tissue or organ where the signal may have originated
Support earlier investigation when results are positive

The test requires a simple blood draw and does not involve radiation or imaging.

Who May Benefit from the Galleri® Test?

The Galleri® multi-cancer blood test may be considered for adults who:

Want a proactive, preventive approach to health
Are generally asymptomatic
Have a family history of cancer
Are concerned about cancers without routine screening options
Prefer advanced screening beyond traditional methods

Dr. Lalezari will help determine whether this test is appropriate based on your medical history and individual risk factors.

Important Considerations

While the Galleri® test offers promising early-detection capabilities, it is important to understand:

It is a screening tool, not a diagnostic test
Not all cancers can be detected
A negative result does not rule out cancer
A positive signal requires follow-up testing

Dr. Lalezari carefully reviews results with patients and coordinates appropriate next steps when needed.

Testing & Follow-Up Care

Blood samples are collected in-office and processed through trusted medical laboratories coordinated with Cedars-Sinai Medical Center when applicable.

If a cancer signal is detected, Dr. Lalezari will guide you through additional diagnostic testing, specialist referrals, and care coordination to ensure timely and thorough follow-up.
