A single blood test that screens for 50+ types of cancer — including many with no standard screening tests available. 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. **Clinical use:** 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). ## Who should order it? 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. ## Biomarkers measured - Cell-Free DNA Methylation Patterns - Cancer Signal Detection - Cancer Signal Origin ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $949.99 | $955.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served.

A Galleri Multi-Cancer Early Detection Test 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. | Where you order | Price | One test, all-in | Notes | | --- | --- | --- | --- | | TestWell (drawn at Quest or Labcorp) | $949.99 | $955.99 | Includes the one $6 lab processing fee, charged once per order | | Hospital outpatient lab, self-pay (typical) | $1200.00 | $1200.00 | Reference figure; hospital charges vary widely by facility and are often higher | Lab test codes: Quest test code 13731. ## How do you prepare? No fasting required. No special preparation needed. Results are reviewed by a licensed physician before release. ## Related conditions - Cancer screening (multi-cancer) (Z12.9) - Family history of malignant neoplasm (Z80.9) - BRCA mutation carrier (Z15.01) - Lynch syndrome (Z15.09) ## Common questions about the Galleri Multi-Cancer Early Detection Test test ### How accurate is the Galleri test? 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. ### How much does the Galleri test cost? TestWell charges $949.99 — vs $949 retail direct from GRAIL. Insurance does not cover it. HSA/FSA reimbursement is at the plan's discretion. ### Do I need to fast? No fasting required. The blood draw is a standard tube of blood shipped to GRAIL's CLIA-certified lab. ### What if Galleri detects a cancer signal? 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. ### Should I get Galleri instead of a colonoscopy? 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. ### Is Galleri FDA approved? 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. ## How to order 1.
