Prenuvo vs Function Health vs Ezra: Taiwan Alternative 2026

Full Body Health Screening Trend in the US

An increasing number of Americans are turning to preventive health measures, thanks to health tech startups like Prenuvo, Ezra, and Function Health, which offer advanced full-body MRI scans for early disease detection and comprehensive blood tests for detailed assessments of your overall health. Ezra's recent merger with Function Health brings together advanced imaging and lab testing into one digital platform. Marking the beginning of a true inflection point for Americans and their healthcare, proactive health management is going mainstream in the United States.

Prenuvo and Ezra / Function Health offer full-body scans to help you learn what’s going on inside your body, before you feel sick or notice symptoms. Think of it like getting a “health snapshot” that could reveal early signs of things like cancer, heart problems, or other hidden issues.

These scans rely on MRI technology, a safe, radiation-free, non-invasive way to capture highly detailed images of your internal organs and tissues. 

These startups are breaking boundaries to help people who want to stay ahead of their health, and they are exciting options to consider as they leverage innovative technologies to advance the screening process.

Prenuvo vs Ezra: How the Two Leaders Differ in 2026

If you're weighing Prenuvo vs Ezra, the short version: Prenuvo sells a premium, standardized whole-body MRI experience; Ezra sells a more affordable, AI-accelerated full body scan that now plugs into a larger lab-testing platform.

Prenuvo is focused entirely on high-resolution imaging using proprietary MRI protocols. They operate their own clinics and offer a fully standardized, premium experience — but the core US$2,499 whole-body scan doesn't include lab work or biomarkers (that's reserved for their US$3,999 Enhanced package, which adds body-composition analysis and blood testing). Every scan is read by a radiologist, and reports arrive in about a week or two.

Ezra took a different path: AI-assisted MRI protocols that cut scan time (their fastest full body scan runs about 30 minutes), which is how they pushed entry pricing down to roughly US$499–899 depending on scan coverage and promotion. Ezra also offers low-dose computed tomography (CT) in addition to MRI — CT is often the better modality for lung screening and coronary calcium scoring, two things MRI handles poorly.

The Function Health Ezra merger (announced May 2025) is what changed the calculus. Function Health built its name on a US$499/year membership covering 100+ lab biomarkers; folding Ezra's imaging into that platform positions the combined company as a broader preventive-health subscription — imaging plus bloodwork in one app. If you want a US-based, subscription-style entry into preventive screening, that combination is compelling.

Worth a mention: Neko Health (the Daniel Ek-backed body-scan startup) opened in New York in 2026 at around US$400 per visit. It's a sensor-and-blood scan rather than a true full body MRI — useful for skin, heart, and vascular markers, but it won't image your organs, and waitlists are long.

What Does a Full Body Scan Cost in 2026?

Here's the comparison that matters — what you actually get for your money across Prenuvo, Ezra / Function Health, Neko, and a hospital-based full body scan in Taiwan:

US figures are published cash prices as of early 2026 and vary by location and promotion; Taiwan pricing depends on the package scope. The pattern holds across the board: for the price of Prenuvo's base MRI alone, a Taiwan package typically covers imaging plus bloodwork plus specialist consultation.

Should You Consider a Full-Body MRI or Taiwan’s Holistic Health Screening Offerings?

While these US startups are making waves in preventive health services, East Asian countries like Taiwan have been doing this affordably, thoroughly, and efficiently for decades. While any preventive check-up is a net positive for one's health, Taiwan takes a holistic approach that you will not find in the U.S. 

1. It’s a longstanding practice and medically rigorous.
Taiwan has been a pioneer in offering comprehensive health screening packages that are deeply integrated into the healthcare system. In addition to the examinations, holistic screenings are all interpreted by board-certified physicians, often on the same day. It’s also common to request additional specific imaging, lab tests, and examinations based on medical history needs. See this blog post for a deeper introduction.

2. It's fast, streamlined, and efficient.
Screenings in Taiwan are typically completed in a half day to a full day, with results and physician consultations included at the end. This experience combines different specialty and departments into a single, holistic experience. Whereas checkup options in the United States may require multiple visits to different specialties across different clinics or departments, and  accompanied with long waits for results.

3. It’s significantly more affordable.
In the U.S,. a holistic check-up will require visit to multiple clinics and physicians, and each appointment would have its own co-pay and fees, even if your insurance covers premium preventive care (most do not). Even with Function Health’s newly launched pricing plans, Taiwan offers these same comprehensive packages at a fraction of the cost without compromising high quality care and also includes more tests. 

4. It’s trusted by locals and expats alike.
Regular health screenings have been a cultural norm in Taiwan, offered as employer benefits and taken seriously by locals. Because of this benefit, most young professionals begin regular health screenings starting in their 20s. Beyond the local clinics and hospitals, New Dawn Health partners with health providers who have exemplary service quality that is akin to top-rated hotel hospitality services. Not only can our providers service English-speaking customers and provide medical reports in English, but the experience on-site is almost a luxury retreat. 

Bonus: You can combine it with travel.
Taiwan has become a preferred destination for health and wellness-focused travelers seeking reliable and affordable health screenings. Whether you're already visiting Taiwan or considering the trip, screenings can be scheduled around your itinerary. And if you're part of the Taiwanese or Chinese diaspora, a screening slots naturally into a trip home — see our guide to returning to Taiwan for a health checkup.

A Full Body Scan in Taiwan: What’s Actually Included

The biggest difference isn't the scanner — Taiwan's top screening centers run the same modern 3T MRI machines Prenuvo and Ezra use. The difference is scope. A US full body scan gives you imaging (and, with Function Health, bloodwork through a separate membership). A Taiwan screening package is built like a one-day medical workup:

Imaging: full-body or targeted MRI, low-dose lung CT, coronary calcium scoring, abdominal and thyroid ultrasound — matched to your age, sex, and family history rather than one-size-fits-all.

Labs: comprehensive blood panels including tumor markers (AFP, CEA, CA 19-9, CA-125, PSA and more), metabolic and cardiac markers — the kind of panel that costs around US$150 in Taiwan versus ~US$1,200 at US labs.

Procedures: optional sedated (painless) colonoscopy and gastroscopy on the same visit — something no US scan startup offers, and a US$2,000–3,800 cash procedure at home.

The readout: a board-certified physician walks through preliminary findings the same day, and the complete English report follows in about two weeks — ready to hand to your US physician.

Which Full Body Scan Should You Choose?

Choose Prenuvo if you want the most polished, standardized whole-body MRI in the US and the US$2,499 price isn't a blocker.

Choose Ezra / Function Health if you want a US-based scan under US$1,000 and like the idea of imaging plus year-round biomarker tracking in one platform.

Choose a Taiwan screening package if you want the widest scope for the money — imaging, labs, endoscopy, and physician consultation in one day — and you can pair it with a trip. For most travelers the total cost, even counting airfare, lands below a single Prenuvo scan.

Full Body Scan FAQ

Is a full body scan worth it?
For people with family history of cancer or cardiovascular disease, or anyone who wants a health baseline before symptoms appear, a full body scan can surface issues years before they would otherwise be found. The honest counterpoint: whole-body MRI can also surface incidental findings that lead to follow-up testing for things that would never have harmed you. That's exactly why Taiwan's model — where a physician reviews your results with you the same day and can order follow-up tests on the spot — is a meaningfully better wrapper around the same scan.

Does insurance cover Prenuvo, Ezra, or Function Health?
Generally no — elective whole-body screening isn't covered by US insurance, which is why all of these are cash-pay prices. Some visitors use HSA/FSA funds. The same applies to Taiwan packages: self-pay, with itemized English receipts you can submit for HSA/FSA or reimbursement claims.

How long does a full body scan take?
Prenuvo's whole-body MRI takes about an hour; Ezra's AI-accelerated versions run 30–60 minutes. A Taiwan screening package takes longer — half a day to a full day — because it isn't just one scan: imaging, bloodwork, ultrasound, optional endoscopy, and a physician consultation are all packed into the same visit.

Can I get a Prenuvo-style scan cheaper abroad?
Yes. This is the quiet secret of the full body scan boom: the same 3T MRI hardware operates in Taiwan's top hospitals at a fraction of US pricing, wrapped in a more complete medical workup. Factor in that Taiwan is one of the most affordable medical-travel destinations for US travelers, and the math usually favors the trip — especially if you were already planning to visit.
