The Galleri test by GRAIL uses next-generation sequencing to detect cell-free DNA (cfDNA) shed by cancer cells into the bloodstream. It can identify a shared cancer signal across more than 50 cancer types — including pancreatic, ovarian, liver, esophageal, and other cancers that currently have no recommended screening tests. When a cancer signal is detected, the test also predicts the tissue of origin to guide follow-up diagnostic workup. The Galleri test is intended as a complement to, not a replacement for, standard-of-care screenings like mammography, colonoscopy, and PSA. It is recommended for adults aged 50+ or those with elevated cancer risk. In clinical studies, the test demonstrated a low false-positive rate (0.5%) and detected cancers across all stages, though sensitivity is higher for later-stage cancers. A negative result does not rule out cancer. This is a premium screening test performed and billed by GRAIL, Inc.
Multi-cancer early detection (MCED) blood test from GRAIL that detects circulating tumor DNA fragments from 50+ cancer types — most of which have no standard screening (pancreatic, ovarian, esophageal, stomach, head/neck).
Adults 50+ (per GRAIL labeling) or younger adults with family history, BRCA/Lynch syndromes, or known cancer risk factors. Best used in addition to (not replacing) standard screening like mammogram, colonoscopy, and Pap.

A Galleri Multi-Cancer Early Detection Test costs $949.99 at TestWell — $955.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Hospital outpatient labs typically bill around $1200.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.

Per GRAIL's PATHFINDER and CCGA-3 studies: specificity 99.5% (low false-positive rate), but sensitivity varies by cancer stage — ~17% for stage 1, ~76% for stage 4. It's most useful as a complement to standard screening, not a replacement.
TestWell charges $949.99 — vs $949 retail direct from GRAIL. Insurance does not cover it. HSA/FSA reimbursement is at the plan's discretion.
No fasting required. The blood draw is a standard tube of blood shipped to GRAIL's CLIA-certified lab.
A positive result includes a 'cancer signal origin' prediction (e.g., 'GI', 'hematologic', 'head/neck'). Your clinician orders targeted imaging or biopsy based on that prediction. Galleri itself doesn't diagnose cancer — it triggers a workup.
No — Galleri's sensitivity for early colorectal cancer is much lower than colonoscopy. It complements traditional screening. Continue colonoscopy, mammogram, Pap, lung CT (if smoking history) on standard schedules.
Galleri is offered as a Laboratory Developed Test under CLIA. The FDA has granted Breakthrough Device designation but it is not yet FDA-approved as a screening device.
Galleri Multi-Cancer Early Detection Test results are typically ready in 10–14 business days after your draw at Quest. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.
