Available to eligible Labs by Hims customers, it combines GRAIL’s Galleri multi-cancer early detection technology with appointment scheduling, results, and support through the Hims platform.
That sounds straightforward, but the details matter. The test does not diagnose cancer, cannot detect every cancer, and is not a replacement for routine screening such as colonoscopy or other tests recommended by your healthcare provider.
What Is the Hims Multi-Cancer Test by Galleri?
The Hims Multi-Cancer Test by Galleri is an annual blood screening test. It analyzes DNA fragments circulating in the bloodstream for methylation patterns associated with cancer.
If it identifies a cancer signal, the test also predicts the tissue or organ where that signal is most likely to have originated.
In a clinical validation study, Galleri detected a signal shared by more than 50 cancer types. These include cancers such as lung, pancreas, and liver cancer, among others.
Not every listed cancer occurs in both males and females, and detection performance is not the same for every cancer type or stage.
Most importantly, Galleri is a screening test—not a diagnostic test. A “Cancer Signal Detected” result requires follow-up diagnostic evaluation using medically established procedures, which may include imaging, laboratory tests, or a biopsy.
How Does the Galleri Cancer Blood Test Work?
Cells release small DNA fragments into the bloodstream. Cancer cells can release fragments with distinct methylation patterns—chemical markers that help regulate how genes behave. Galleri uses these patterns and machine learning to answer two questions:
- Is a cancer-associated signal present?
- If a signal is present, where in the body did it most likely begin?
The test is a point-in-time screen. It does not analyze inherited genetic risk and does not predict whether you will develop cancer in the future.
How the Hims Testing Process Works
For an eligible customer, the process generally follows four steps:
- Complete the eligibility questions. The test is available by prescription and is not offered in every state.
- Add the test to a Labs by Hims plan. Hims states that you must be a Labs by Hims & Hers customer to purchase it. The subscriptions are bundled and renew based on the original Labs purchase date.
- Schedule a blood draw. Appointments can be booked through the Hims app at more than 2,000 Quest Diagnostics locations. Hims says no fasting or special preparation is required.
- Review the result and next steps. Results are delivered through the app as either “Cancer Signal Detected” or “No Cancer Signal Detected.” If a signal is detected, Hims says a provider will typically contact the customer within 15 hours to discuss the result.
Testing is recommended annually, but a healthcare provider can help determine whether it is appropriate for your individual health history and risk profile.
Who May Be a Candidate?
Galleri is recommended for adults with an elevated risk of cancer, such as people age 50 or older. Age is only one risk factor. Personal medical history, family history, tobacco exposure, and other factors may also shape an individual discussion with a healthcare professional.
Galleri’s safety information says use is not recommended for people who are pregnant, age 21 or younger, or undergoing active cancer treatment. Eligibility and a prescription are required, and availability varies by state.
This test is not designed for someone seeking an answer about a new lump, unexplained bleeding, persistent pain, unintended weight loss, or another concerning symptom.
Symptoms warrant prompt medical evaluation; a screening result should not delay care.
What Do Galleri Test Results Mean?
Cancer Signal Detected
This result means the test found a DNA pattern associated with cancer and will report a predicted Cancer Signal Origin. It does not mean cancer has been diagnosed. The next step is an in-person medical evaluation and appropriate diagnostic testing.
A positive screening result can be false. Galleri’s current healthcare-professional materials report 99.6% specificity in the cited PATHFINDER 2 data, equivalent to an approximate 0.4% false-positive rate among people without cancer in that study population.
Individual experience can differ, and a positive result can still lead to additional appointments, imaging, procedures, cost, and anxiety.
No Cancer Signal Detected
This result means the test did not find a cancer-associated signal at the time of the blood draw. It does not rule out cancer. Some cancers shed little or no detectable DNA into the bloodstream, and false-negative results occur.
A negative result also does not predict future health. Continue routine screening, attend regular checkups, and seek medical advice about symptoms even when Galleri reports no signal.
Benefits and Important Limitations
The Hims pathway may also simplify scheduling and access to results for existing Labs customers.
However, anyone considering the test should understand its limits:
- It does not diagnose cancer.
- It does not detect every cancer or every case of the cancers it screens for.
- False-positive and false-negative results occur.
- A detected signal can lead to follow-up tests and procedures.
- A no-signal result does not rule out cancer or future cancer risk.
- It does not replace guideline-recommended screening.
- It is a laboratory-developed test whose performance characteristics were determined by GRAIL. According to current Hims and Galleri materials, it has not been cleared or approved by the U.S. Food and Drug Administration.
- The Galleri test has not yet been shown to reduce cancer deaths or improve overall survival.
These limitations make shared decision-making important. Consider what you would do with either result, how follow-up care would be coordinated, and whether your insurance would cover diagnostic testing prompted by the screen.
Does Galleri Replace Routine Cancer Screening?
No. Galleri should be used in addition to screenings recommended by your healthcare provider. Depending on age, anatomy, and individual risk, those may include colorectal, breast, cervical, lung, or prostate cancer screening.
Routine screening tests are designed and studied for specific cancers. A multi-cancer blood test does not make them optional.
Staying current on established screening remains essential regardless of a Galleri result.
Questions to Ask Before Ordering
Before purchasing the Hims Multi-Cancer Test by Galleri, consider discussing these questions with a healthcare provider:
- Does my age, family history, or exposure history place me at elevated cancer risk?
- Am I up to date on standard cancer screenings?
- What are the possible benefits and harms for someone with my risk profile?
- Who will coordinate follow-up if a cancer signal is detected?
- What diagnostic tests might be needed, and how would they be paid for?
- Could any current symptoms require direct evaluation instead of screening?
- How might I respond emotionally to an uncertain or false-positive result?
Frequently Asked Questions
Is the Hims Multi-Cancer Test by Galleri FDA approved?
No. Current Hims and Galleri materials state that Galleri has not been cleared or approved by the FDA. It is a laboratory-developed test performed by GRAIL’s CLIA-certified, College of American Pathologists-accredited laboratory.
How many cancers does the Hims Galleri test screen for?
In a clinical study, Galleri detected a signal shared by more than 50 types of cancer. It does not detect every cancer, and sensitivity varies by cancer type and stage.
Can Galleri tell me whether I have cancer?
No. Galleri is a screening test. A Cancer Signal Detected result requires confirmatory diagnostic evaluation before cancer can be diagnosed.
Does a No Cancer Signal Detected result mean I am cancer-free?
No. A no-signal result does not rule out cancer. False-negative results occur, and some cancers may not release enough DNA into the blood to be detected.
Do I still need a colonoscopy or other routine screening?
Yes. Galleri is intended to complement—not replace—routine cancer screenings recommended by a healthcare provider.
How often is the Hims Multi-Cancer Test by Galleri taken?
Hims recommends the blood test annually. Your healthcare provider can help you decide whether repeat testing is appropriate.
Is insurance required?
Hims states that insurance is not required to order the test. Before purchasing, confirm the current price and consider that follow-up diagnostic care may have separate costs and insurance coverage rules.
