Why order the Galleri cancer test through My IV Doctors
Advice before you buy
A free consultation helps you decide whether a $999 test that adds to, but never replaces, routine screening makes sense for your age and risk.
A clinician's order
A licensed U.S. clinician orders Galleri for you and sends clear instructions for arranging your blood draw.
Results explained plainly
Your clinician reviews your report with you, including what a cancer signal or a no-signal result does and does not mean.
Next-step guidance
If a cancer signal is detected, you get guidance on the follow-up imaging or other diagnostic tests needed to confirm or rule out cancer.
How to order the Galleri test online
- 1
Pick a time for your free visit
In a free 5–10 minute phone or video consult, you'll talk through your age, history, current screening and what the test can and can't tell you.
- 2
Get your Galleri test order
Galleri requires an order from a licensed clinician. If it's appropriate, yours is placed and you receive instructions for your blood draw.
- 3
Give a blood sample
The sample is collected at a draw location arranged after your order and sent to GRAIL's laboratory.
- 4
Get your result
Results usually take a couple of weeks after the lab receives your sample. You'll be told either that no cancer signal was detected or that a signal was detected, with a predicted origin.
- 5
Plan your next steps
Your clinician explains the result. A detected signal needs diagnostic follow-up, typically coordinated with your primary care doctor or a specialist.
Who should get the Galleri test
Adults 50 and older
Cancer risk rises with age, and this is the group GRAIL has mainly studied and is seeking approval for.
People at higher risk
A strong family history or other risk factors may make an additional screening layer worth discussing with a clinician.
Up to date on routine screening
Galleri works best as an extra step after recommended screenings, not as a shortcut around them.
Ready for follow-up testing
If a signal is found, you'll need diagnostic tests through your own health care providers, and you should be ready for that before ordering.
Not for symptoms or active cancer
Galleri isn't meant for people who are pregnant, are 21 or younger or are being treated for cancer, and it's not a way to investigate symptoms. New symptoms need an in-person evaluation.
Galleri test vs. standard cancer screening
| Feature | Galleri blood test | Standard screening tests |
|---|---|---|
| What it looks for | A signal shared by many cancer types | One cancer at a time |
| Sample | One blood draw | Imaging, scope, stool or cell sample |
| FDA status | Not FDA-approved | Established, guideline-recommended tests |
| Result | Signal or no signal; needs follow-up if positive | Depends on the test |
| Role | Adds to routine screening | Recommended by age and risk |
What the Galleri cancer test looks for
Most proven cancer screening tests look for one cancer at a time: a mammogram for breast cancer, a colonoscopy or stool test for colorectal cancer, a Pap or HPV test for cervical cancer, and low-dose CT for lung cancer in people at high risk. Many other cancers have no routine screening test at all.
Galleri takes a different approach. It examines fragments of DNA that cells release into the blood, looking for chemical patterns (methylation) associated with cancer. GRAIL says the test can detect a signal shared by more than 50 types of cancer, and when it finds one it predicts where in the body the signal most likely came from.
A result is not a diagnosis. A positive result means more tests, such as imaging and possibly a biopsy, are needed to find out whether cancer is present. A negative result does not rule cancer out. Galleri is not FDA-approved, and whether multi-cancer tests reduce deaths from cancer is still being studied.
Galleri test results explained
No cancer signal detected: this is the most common result. It's reassuring but doesn't prove you are cancer-free, because the test can miss cancers, particularly early-stage ones. Keep up with all your recommended screenings and report new symptoms promptly.
Cancer signal detected: the report includes a predicted cancer signal origin, which helps guide where to look first. Diagnostic tests such as imaging, scopes or a biopsy are needed to confirm or rule out cancer. Some people with a detected signal turn out not to have cancer, which is called a false positive.
Galleri test accuracy and FDA status
Multi-cancer tests are a fast-moving area. The National Cancer Institute notes that these tests have generally been better at finding advanced cancers than early ones, and that more research is needed to show whether they reduce cancer deaths. NCI has launched the Vanguard Study to learn how such tests perform in people without cancer.
GRAIL applied to the FDA for premarket approval of Galleri in January 2026, and in September 2026 an FDA advisory panel voted that its benefits outweigh its risks for adults 50 and older. The panel's vote is advice only. When this page was reviewed, the FDA had not made a decision, so Galleri remains a laboratory test that is not FDA-approved. That also means insurance rarely covers it.
Galleri vs. standard cancer screening
Galleri is designed to sit alongside standard screening. For example, the CDC notes that the U.S. Preventive Services Task Force recommends colorectal cancer screening for adults 45 through 75. Breast, cervical and, for eligible people, lung cancer screening also remain important regardless of a Galleri result.
Galleri test risks and limitations
The blood draw is low risk. The main risks come from what a result can lead to, which is why a clinician discusses the test with you first.
- False negatives: the test does not detect every cancer and is less sensitive for early-stage disease.
- False positives: a signal may be found when no cancer is present, leading to further tests that carry their own risks and stress.
- Follow-up diagnostic tests may involve radiation, procedures or biopsies, and may not be covered by insurance.
- Galleri is not FDA-approved and is not a replacement for any recommended screening test.
- Do not use Galleri to investigate symptoms; see a clinician in person for new or worsening symptoms.

Galleri cancer test FAQs
Still deciding? The first consultation is free and takes about 5–10 minutes.
Book a free consultationWhat is the Galleri test?
Galleri is a multi-cancer early detection blood test made by GRAIL. It looks for DNA methylation patterns linked to cancer in fragments of DNA circulating in the blood, and predicts the likely origin if a signal is found.
How much does the Galleri test cost?
The Galleri test is $999. The first consultation is free and a results review with a clinician is included. Insurance generally doesn't cover it.
Is Galleri FDA-approved?
No. GRAIL has applied for FDA approval, and an FDA advisory panel voted in its favor in September 2026, but the FDA had not made a decision when this page was reviewed. It is currently available as a laboratory test ordered by a licensed clinician.
Does Galleri replace a colonoscopy or mammogram?
No. Galleri complements standard screening and doesn't replace it. Keep up with colorectal, breast, cervical and, if eligible, lung cancer screening.
What does a positive Galleri result mean?
It means a cancer signal was detected, not that you definitely have cancer. Diagnostic tests such as imaging or a biopsy are needed to confirm or rule out cancer, guided by the predicted origin.
Can Galleri miss cancer?
Yes. A negative result lowers the chance that one of the cancers it looks for is present, but it can miss cancers, especially at early stages. Continue routine screening and report new symptoms.
Do I need a prescription for the Galleri test?
Yes. Galleri must be ordered by a licensed clinician. During your consult, the clinician decides whether the test is appropriate and places the order if so.
Who should get the Galleri test?
It has mainly been studied in adults 50 and older and in people with elevated cancer risk. It isn't intended for people who are pregnant, are 21 or younger or are in active cancer treatment.
How long do Galleri results take?
Results usually take a couple of weeks after the lab receives your sample. Your care team will tell you when to expect them.
What happens after a cancer signal is detected?
Your clinician explains the result and helps you arrange diagnostic follow-up, usually with your primary care doctor or a specialist. Those tests aren't included in the $999 price.
How often should you get the Galleri test?
Some people repeat it once a year, but the best interval for multi-cancer testing has not been established. Your clinician can talk through whether repeating it makes sense for you.
Is the Galleri blood test painful?
It's an ordinary blood draw, so you may have brief discomfort or a small bruise. The larger consideration is the follow-up testing a result can lead to.
Can I take the Galleri test if I have symptoms?
Galleri isn't designed to investigate symptoms. If you have unexplained weight loss, bleeding, a lump or other new symptoms, see a clinician in person for a diagnostic workup.
