The limbo between having blood drawn and receiving the results can be stressful for patients. Then the jargon-filled blood test report arrives before a doctor can review it and translate the findings. They may never follow up if they see no cause for alarm. 

Enter the artificial intelligence-powered chatbot. Since major large language models like ChatGPT, Claude, and Gemini debuted a few years ago, an increasing number of patients have shared their lab results — or uploaded them to — the chatbot of their choice, seeking guidance.

Companies, including the wellness and lifestyle brands Whoop and Levels, see an opportunity in this information gap and have made a compelling pitch: Concierge-level attention to a consumer's lab work, courtesy of AI. 

Typically, their AI product is an explanatory report, written in accessible language, that provides a personalized plan with next steps, like dietary changes, lifestyle modifications, and consultation with a doctor. The service, which is typically available with a subscription, can cost a few hundred dollars or more per year.  

Dr. John Whyte, CEO of the American Medical Association, understands the appeal, especially when patients find their results confusing. 

"Physicians are [not always] the best communicators," Whyte says. "I wish we were, and [that we] had more time." 

Still, he says there's no rigorous research or evidence demonstrating that AI can effectively and accurately interpret blood results and make personalized lifestyle recommendations to improve or optimize one's health. In other words, the companies offering AI interpretation of blood tests don't yet know if their product is better than simply consulting a chatbot for free, or more accurate than a doctor's opinion.  

"I think you have to be skeptical about some of the claims," Whyte says.

AI for blood test results still has a long way to go.

The AI models, including Gemini and ChatGPT, used by companies that do blood interpretation work aren't validated or benchmarked for this purpose, according to their makers, Google and OpenAI.

When Google recently partnered with Quest Diagnostics to bring an AI tool to customers of the nationwide lab work company, it focused on explaining medical terminology, identifying trends in their personal data, and suggesting questions to ask their doctor. It does not give medical guidance or lifestyle advice.

A spokesperson for the company said that while Google frequently publishes research on Gemini's medical benchmarks, the Quest partnership is designed to "solve real-world literacy and data-navigation challenges for patients."

OpenAI's HealthBench, which tests how well its models perform on realistic health scenarios, includes examples of understanding blood results, according to a company spokesperson. Still, OpenAI doesn't have a standalone benchmark for blood testing. 

Jonathan Kron, co-founder and CEO of the company BloodGPT, readily acknowledges that there are no widely accepted benchmarks for comprehensively interpreting blood tests at scale. 

During its early testing in 2024, BloodGPT found that uploading full lab reports directly to general-purpose chatbots like Claude and ChatGPT consistently yielded errors. Biomarkers were missed entirely or confused with each other. Sometimes the chatbot hallucinated recommendations. 

These experiences prompted BloodGPT to build what it calls a "structured pipeline" with multiple checks for validating its findings. While BloodGPT can swap out large language models based on their evolving strengths, the company currently uses enterprise Gemini, OpenAI, and Anthropic models for different tasks, including classification, reasoning, interpretation, and consistency checking. It also consults with specialists on specific biomarkers, like the reproductive hormones estrogen and testosterone, to check the accuracy and insight of its AI. 

Though BloodGPT considers its primary business selling software to other companies, including clinical laboratories, healthcare systems, and health diagnostic companies like LabCorp, it offers AI interpretation to individual consumers. Their consumer plans range from $9.99 to $17.99 per month.

The company says its algorithms are based on established clinical guidelines and validated medical reference data, and are tested iteratively by clinicians. BloodGPT hasn't published peer-reviewed research proving the success of its methods — yet. 

Kron says the company will embark on a massive research project using 100,000 de-identified patient records through a partnership with an Israeli health system. The goal is to benchmark BloodGPT's accuracy in multiple ways against the results contained in the patients' medical records. 

"We're not choosing the easy way here," Kron says.

Dr. Girish N. Nadkarni, an internist and nephrologist at New York's Mt. Sinai Hospital, argues that companies selling an AI blood interpretation service need to demonstrate their success by comparing it retrospectively against de-identified patient data and by enrolling people in a prospective study that compares their AI findings to an expert's.

"I don't think that anything has to have 100 percent accuracy to succeed, because humans are not 100 percent accurate," says Nadkarni, an AI health researcher and director of Mt. Sinai's Hasso Plattner Institute for Digital Health. "But the conversation becomes really hard because I don't know what the accuracy of this model is…how does it work, and where does it fail?" 

Nadkarni says current AI blood work products might be "OK" for a majority of patients, but problems may emerge at the extremes, such as missed diagnoses or false positives that cause anxiety and potentially harmful additional testing. 

Levels CEO Josh Clemente is an advocate of frequent blood testing. If cost weren't a concern, Clemente would recommend lab work far more often than the typical annual physical, for pro-active health monitoring.

Levels, which focuses on metabolic health, markets its subscription plans as a way to "live healthier, longer." Each tier offers access to the company's app and proprietary dashboards, along with glucose monitoring. But only two tiers, available for $499 and $1,499 annually, include lab work, clinician-reviewed reports, and AI health insights. 

Clemente currently favors Claude and Gemini for the Levels AI product, which is also trained on medical articles and biomarker research, plus Levels blog posts and podcasts featuring metabolic experts on topics like diet, weight loss, and hormones. 

The AI product derives its insight from these layers of information and guardrails, and a doctor reviews every lab work report that a consumer receives. An app-based AI chatbot also draws from Levels expert content to recommend lifestyle changes that could improve biomarkers like cholesterol and glucose. 

"We're using it again as a clinician support tool, which is, in my opinion, the right way to use these tools today," Clemente says. Levels is not currently conducting independent research on the accuracy of its AI product. 

Nadkarni supports human oversight, but cautions consumers against believing this is a failsafe. Instead, physicians can unwittingly fall victim to automation bias, or the tendency to rubber-stamp AI outputs. 

Can AI truly personalize blood test results?

Whoop, the wearable made famous by athletes like soccer star Cristiano Ronaldo and quarterback Patrick Mahomes, just began offering blood testing last fall. One annual test is $199, but members can test six times a year for $899. The company partners with Quest to perform the lab work and, like Levels, has a physician review the results. 

Alexi Coffey, vice president of product at Whoop, says the company's AI product is powered by OpenAI and individual member data. She declined to comment on whether the company is pursuing clinical research on the accuracy of its AI. 

"We never want to over claim or over suggest relationships between things," Coffey says, "but we do want to provide value to our members by helping them understand things that may be connected." 

Coffey says that Whoop's ability to integrate physiological data — including heart rate, sleep quality, and exercise patterns — into blood work reports gives customers unique health insights. 

If, for example, a customer ran a marathon the day before their blood was drawn, the AI might take the physical stress into account when interpreting inflammation biomarkers. (Whoop actually advises its members to avoid strenuous physical activity prior to a blood draw because it may influence the results.) 

As promising as this sounds, Whyte, of the AMA, says there's no evidence demonstrating that such AI applications are "truly personalized." 

"I think we really have to question what the data is," he says, noting that companies would need a massive dataset to make individual recommendations. If these companies have that information, they haven't published peer-reviewed research based on it yet.

Blood tests are crucial diagnostic tools, Whyte says, but they're also the focus of social media hype, which often positions them as a silver bullet for fixing health challenges like low energy or sleeplessness. He warns consumers that some companies measure elements and minerals that "are not that helpful for anything." Hormone level testing can be similarly futile, depending on how it's done.

Until scientific research establishes the accuracy and meaningfulness of AI blood test interpretation, Whyte recommends patients use AI to help plainly explain their results, rather than relying on the technology to generate personalized insights for them. 

"People think a lab test is black and white and it's the final ruler on whether you have disease or not," Whyte says. "And that's not always true."

Disclosure: Ziff Davis, Mashable’s parent company, in April 2025 filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.

It's the Third Quarter tonight, which means we're exactly halfway in between the Full Moon and the New Moon. This is part of the Moon's roughly 29.5 day cycle that sees it move through eight different phases. Keep reading to see what that means for tonight's Moon.

What is today’s Moon phase?

As of Friday, April 10, the Moon phase is Third Quarter. Tonight, 49% of the moon will be lit up, according to NASA's Daily Moon Guide.

Tonight, without any visual aids, you should be able to see the Oceanus Procellarum, Tycho Crater, and the Copernicus Crater. With binoculars, you'll also be able to see the Grimaldi Basin, the Mare Humorum, and the Clavius Crater. Finally, if you have a telescope, expect to see features like the Schiller Crater and the Fra Mauro Highlands.

When is the next Full Moon?

The next Full Moon is predicted to take place on May 1, the first of two in May.

What are Moon phases?

According to NASA, it takes the Moon roughly 29.5 days to orbit Earth, passing through eight distinct stages during that time. While the same side of the Moon always faces us, the amount of sunlight hitting it changes as it moves, which is why it can look full, partly lit, or just a slim crescent. These shifting appearances are known as the lunar phases, and there are eight in total:

New Moon - The Moon is between Earth and the sun, so the side we see is dark (in other words, it's invisible to the eye).

Waxing Crescent - A small sliver of light appears on the right side (Northern Hemisphere).

First Quarter - Half of the Moon is lit on the right side. It looks like a half-Moon.

Waxing Gibbous - More than half is lit up, but it’s not quite full yet.

Full Moon - The whole face of the Moon is illuminated and fully visible.

Waning Gibbous - The Moon starts losing light on the right side. (Northern Hemisphere)

Third Quarter (or Last Quarter) - Another half-Moon, but now the left side is lit.

Waning Crescent - A thin sliver of light remains on the left side before going dark again.

Like unsung Australian horror movie Bait, Netflix's Thrash knows that tsunamis are least of your worries after a Category 5 hurricane hits in a movie. Sharks (yes, sharks) wash in with the tide in the latest from writer/director Tommy Wirkola (Violent Night, Dead Snow), and it's a proper nail-biter.

With nightmare-inspiring cinematography, increasingly flooded and crumbling sets, impossibly risky scenarios, and solid performances from Djimon Hounsou, Whitney Peak, and Phoebe Dynevor, Thrash earns its place in the long, storied history of shark survival movies.

Climate disaster films come in all genres, and in Thrash (notably produced by Don't Look Up's Adam McKay), Wirkola leans into the extreme weather impact of a warming planet without addressing it directly. Climate change doesn't cause extreme weather events; climate change increases the intensity, frequency, and duration of extreme weather events. And nothing's more extreme than watching a Category 5 hurricane absolutely pummel the town of Annieville, South Carolina, with fierce winds, destructive flooding, and sharks swimming down Main Street. (I'm not here to evaluate the scientific accuracy of this film.)

Here, we meet several citizens left behind: Whitney Peak as Dakota, who turns off weather reports to watch videos of her recently passed mother; Phoebe Dynevor as Lisa, a meatpacking factory executive who could give birth any moment now; and Stacy Clausen, Alyla Browne, and Dante Ubaldi as Hanson the Olsens, a trio of siblings whose crooked foster parents see the storm as "just a little bit of weather." Elsewhere, Djimon Hounsou's en route as oceanic researcher Dale, who spotted bull sharks coming in with the storm, seeking shelter in freshwater estuaries. He also happens to be Dakota's uncle.

You'll genuinely cheer for these characters as they find themselves suddenly huddled on their kitchen benches, perched on their roof, and on the brink of labor as the floodwaters rise. It's not an easy feat to craft characters you don't want to see as shark bait in a movie like this, and Thrash's cast manage it with finesse, despite Wirkola giving us very little information about them. Peak's physicality doesn't miss a beat, combining Ninja Warrior obstacle courses with convincing anxiety symptoms, Hounsou's overt authority grants the film legitimacy, and as for Dynevor, well, labor scenes don't happen like this every day. (And yes, I feel the soundtrack in Lisa's scenes is internet bait, but I'm not mad about it.)

Thrash is a brutal flood of visual effects and jaw-dropping cinematography. This scene had me pacing. Credit: Ben King / Netflix

Although Thrash is a high-budget Netflix film, the nail-biting scenarios Wirkola throws down are simple; often, it's getting from A to B across shark-infested waters. Like fellow contained shark horrors The Reef, Open Water, The Shallows, and more recently Under Paris, Thrash pushes its characters into survival situations where simply travelling across a tiny stretch of water seems unthinkable. Here, Wirkola stays far from the supershark territory of The Meg or Deep Blue Sea, keeping his marine predators life-size and emphasizing their more terrifying behaviours. However, he does stick to certain shark movie requirements, like characters being suddenly vertically dragged underwater and shark vision camera angles.

Production designer David Ingram builds an increasingly flooded and destroyed town, an impressive and sadly all-too-real vision of disaster — and one which makes for stressful action sequences. Director of photography Matthew Weston's shots consistently resemble horror movie posters, from a teen teetering over a kitchen doorway as a shark sails underneath to a rooftop SOS with sharks circling below. Each overhead moment plays with shadow, scale, and suspense to up the danger, before editor Martin Stoltz takes us back into the action. And as for action, Thrash throws every last visual effect at sequences like the shocking storm surge, which decimates the entire town of Annieville within minutes.

Make no mistake, Thrash is brutal. The bull sharks, in particular, make for vicious villains, with the species' signature aggressive tendencies displayed with gruesome work from visual effects supervisor Bryan Jones and his team. (At the risk of sounding like bull sharks' publicist, bull shark attacks are extremely rare).

If you like shark movies, Thrash is a solid survival thriller with a talented cast and visuals that had me locked in. Wirkola's ability to balance horror, action, and comedy remains a praise-worthy feat. Dive into it.

Thrash premieres on Netflix April 10.
