Is in-depth and expensive blood work worth it?
But increasingly, folks looking to optimize their health are taking a new approach to blood work, seeking out the tests and reading them like tea leaves. Results aren't just to indicate sickness or stressors. They're supposedly a gateway into more energy, better sex and a happier, longer, life.
That's the selling point for a number of companies offering full blood-work panels outside of regular doctor visits. Brands like Life Labs, The Bespoke Wellness Group and Inside Tracker tout the benefits of personal analytics based on blood work. The detailed information gives you a more complete understanding of both how your body works now and how it might work better.
It's info that comes with costs and risks. Packages including comprehensive testing, pages explaining that data, and personalized follow-up plans run about $600. While companies have privacy policies in place, handing over sensitive information is never 100-per-cent safe, as shown with the recent bankruptcy of 23andMe.
Still, blood work offers factual information about what's going on in your body. Changes to your diet, workout and supplement routines can be shown in the results, offering empirical feedback when health matters can often feel like guesswork. Recently, I underwent a comprehensive blood-work panel from Canadian startup NiaHealth. The hope was that by checking my levels and crunching the numbers, I'd be able to make some changes.
The past few months, I've been feeling exhausted. I've been having trouble completing workouts at the gym. I'm foggy during meetings, and getting up in the morning can feel like a herculean task. Nothing is wrong exactly, but things are not great. With continuing fatigue, I wanted to make sure something else wasn't going on with my health. Because I don't have a family doctor, blood work seemed like one of the best bets to do that.
'I encourage patients to get our blood work done on a semi-regular basis,' said Amanda Jaeger, a naturopathic doctor with Step Up Massage and Rehab.
Naturopaths are limited in what they can offer. Compared with a physician, their focus is generally around optimization rather than medical care. For Jaeger, the tests help zero in on the cause of certain problems and catch things that might not be obvious on a surface level.
'There are things that some people accept as normal − things like period cramps or fatigue − that don't necessarily have to be that way.'
Through her clinic, Jaeger is able to make recommendations for supplementation and lifestyle changes based on numbers in the blood work. Even if folks' biomarker levels are within 'normal' ranges, that can make meaningful impacts on patient's day to day.
'When it comes to reference ranges, there are some stark differences from the lowest to highest. … I'm trying to look for optimal functions rather than normal ranges.'
For my NiaHealth test, I chose a panel with fifty-plus biomarkers plus a testosterone add on. There was also a thirty-minute consultation with a nurse practitioner from their team to explain my results.
While a lot of startups in the blood-work space offer comprehensive biomarkers with their tests, Jaeger notes that most people can get by with less. A complete blood count, a comprehensive metabolic panel, a TSH screening for thyroid, vitamin D and inflammatory markers are cheaper tests or things that can be assigned through public health that give a great overview of what's happening with your body. Still, accessing those tests can be difficult from a walk-in clinic or if you don't have a primary doctor.
My blood work came in less than a week after my visit to a local clinic. During the half hour NiaHealth consultation, a nurse practitioner pointed to borderline cholesterol levels, iron levels above average and some vitamin deficiencies. The website's dashboard offered graphs and grades for my results that were easy to read.
Overall I was at a B+. Suggestions for my diet included trying fatty fish. Offers for exercise included breaking up my walks throughout the day and trying to jog. While I ranked a perfect score for my testosterone, my levels are on the lowest end of normal, and suboptimal, according to previous tests I'd done with InsideTracker.
The nurse practitioner with NiaHealth was kind and informative, but after walking through my levels, there was hardly time to address the fatigue that had jump-started the process. She suggested that to better understand the causes of elevated biomarkers tests would need to be done with my (non-existent) primary-care provider. Nonetheless, getting the blood work done was helpful in planning some next steps. And for some, that can be an absolute game changer.
For former bodybuilder and current fitness coach Dominic Kuza, checking blood work was key to getting lean and achieving physique goals both for himself and his clients. An out-of-pocket blood panel revealed unaddressed thyroid issues that were a major setback for his training, requiring medication and lifestyle changes to get on track. Based in America, his basic blood panel did not include testing for thyroid functions or hormones.
'Through my own blood work I've found things that were completely overlooked by doctors, but this was due to how basic of a panel that a physical with your doctor contains,' said Kuza.
'Blood work gives us information that allows us to see how our body is functioning internally and why someone might be having a hard time progressing in the direction they are hoping to.'
For everything a blood-work panel offers, costs and potential privacy issues are important to consider when deciding whether you'd like to move forward with the work. In the case of NIA Health, it has a privacy policy that says it will not share personal information except in the case of service providers, legal compliance or the sale of the business.
There are also valid concerns that private companies offering health services weakens Canada's universal health care and encourages a two-tier system. Not everyone has the means or desire to spend $600-plus on tests. At the moment, that limits customers to wellness and health fanatics rather than the general public. But knowing the stats on what's happening in your body − and what those stats mean − is one way you can start taking better control of your health.
Without seeing the numbers and some general recommendations from the folks at NiaHealth, any changes would have been largely guesswork. Still, it's a big spend for general feedback such as trying a Mediterranean diet, exercise and the value of vitamin D.
For anyone looking to get the benefits of blood work without breaking the bank, working with your doctor and requesting basic panels is still your best bet.

How 'pervasive' is racism in health care? This B.C. researcher gathers the stories of Black, Indigenous people
Ashley Wilkinson has found racism is an ongoing challenge in health-care settings in Canada, which is why the PhD candidate at the University of Northern British Columbia is getting the first-hand accounts of Black and Indigenous people who say they've experienced it. For her doctoral work, Wilkinson, who's also a research co-ordinator at Lakehead University in Thunder Bay, Ont., has been interviewing unhoused people in various Canadian communities to learn if racism is impacting their efforts to get proper health care. "I've heard everything from micro-aggressions, racial slurs, physical violence, a lot of assumptions being made about people [regarding] substance use and the challenges that they're facing, just based on the fact that they're Indigenous," said Wilkinson. Across the board, all of these interactions have made people very hesitant to go back and seek care. So far, she's met with clients at Positive Living North in Prince George, B.C., and the Calgary Drop-In Centre. This week, she's in Thunder Bay to speak with people at Shelter House, which offers overnight accommodations on the city's south side. "Across the board, all of these interactions have made people very hesitant to go back and seek care," Wilkinson said of the health-care experiences shared with her. "There's been a lot of mistrust historically as well for these communities, and so the experiences that they're having really do have an impact on their care-seeking behaviours moving forward." There is ample research that supports Wilkinson's findings. For example, according to data from a 2024 Statistics Canada survey, about one in five Indigenous people reported experiencing unfair treatment, racism or discrimination from a health-care professional over the previous year. As well, a Public Health Agency of Canada report from 2020 found that discrimination against Black communities is deeply entrenched in the country's institutions, policies and practices — as a result of European colonization in Africa and the legacy of slavery, which was legal in Canada until 1834. Wilkinson hopes her research can be used to help inform public health-care policies, but she also wants the clients and communities that have participated to have access to her findings. "We know that often, long reports sit on shelves and they don't get read. They're also not accessible to community individuals for whom English might not be their first language or individuals with varying literacy levels." The way in which research on this topic has been done has itself also caused harm among these populations, she added, "so I really want to have this project done in a good way where people walk away feeling like, 'I am doing something' with that story that they've shared." Making research accessible In B.C., since a lot of research is based in Vancouver, Wilkinson wanted to also hear from people in smaller communities, she said. As Thunder Bay is a central hub in northwestern Ontario, many clients at Shelter House have participated in research, said Champagne Thomson, the organization's development manager. "We've seen a very large influx in interested individuals wanting to participate, which is incredible, as well as some individuals who have shared their experiences and said, 'This is the first time anyone's ever taken me seriously. "'This is the first time I've been able to sit across the table with another racialized individual who's listening to me and not speculating about, was it racism or was it not.'" Wilkinson has interviewed about two dozen people so far, with the goal of conducting between 45 and 60 interviews. To make her research accessible, Wilkinson said, she plans to create infographics and shorter, plain language-style reports for participants. "Thunder Bay is a hotspot for a lot of research, and I don't think a lot of it ends up coming back to the individuals that that information was extracted from," added Thomson. "When we're planning, when we're looking at things, when we're investing in different institutions and types of care, I think it's really important that individuals with these lived experiences are able to see their contributions reflected in how that goes forward." 'It's about giving something back' Building relationships is a big part of Wilkinson's project. In Prince George, after interviewing individuals, she participated in harm reduction outreach. Across Calgary and Thunder Bay, she's served meals to hundreds of clients "because I want that relationship in each community and with each organization to be reciprocal." "It's not just about me coming in and extracting that data. It's about giving something back, both now and later at the end of the project." Before each interview, she offers Indigenous participants tobacco and makes sure all the clients are fed and hydrated. She also gives them a cash honorarium and homemade jam "because their time is valuable and their time is worth something." After finishing her work in Thunder Bay, Wilkinson will conduct interviews at a Black homeless-serving organization in Toronto. "As a Black researcher, a Black scholar coming from the [Greater Toronto Area], I think that's going to be a really impactful experience," she said. "In order to create meaningful change, we need people to recognize that the racism we're seeing in our health-care system is pervasive, and by having all of these stories, there's no denying that racism exists anymore — and that's really my goal for this project."

Ontario doctors don't get paid when they treat uninsured patients. Here's how that might change
Several times a week, a man facing homelessness and mental health issues comes to the busy emergency department in downtown Toronto where Dr. Bernard Ho works, and doctors there treat him despite not being paid to do so. That's because the man doesn't have a valid health card — and he's not the only one. Ho said many doctors are forced to bear the cost of caring for people in need who can't prove they have health insurance. "We see them all the time. And unfortunately, we're not paid for them," Ho told CBC Toronto. Currently, most doctors across the province can't invoice the Ontario Health Insurance Plan (OHIP) for patients who can't prove they have coverage. The Ontario Medical Association is hoping to change that and is working to finalize a new compensation deal with the provincial government that includes the reintroduction of what it calls a "good-faith" payment policy, first scrapped in 1998. What is a 'good-faith' payment policy? During the COVID-19 pandemic, Ontario revived a version of 20th-century "good-faith" payment policy, creating a stream of funding to ensure doctors got paid whenever they treated someone, even when the patient was not insured. The policy was scrapped again in 2023. The Ministry of Health told CBC Toronto in a statement it's unable to comment on specific proposals while in active bargaining with the OMA. If the proposal is approved, the "good-faith" payment system would kick in under three scenarios, according to the OMA: Newborn patients experiencing glitches or delays while they await a permanent health card. People who are OHIP-eligible but don't have valid documentation or valid coverage, a category which could include people experiencing homelessness, mental health issues or other barriers to documentation. Uninsured patients presenting in critical conditions, who are unable or don't have someone available to provide documentation. The category could include undocumented residents, temporary residents experiencing lapses in coverage, uninsured travelers facing medical emergencies, and individuals facing complications or emergencies after elective health or birth tourism. 'Free for all' not the goal, OMA president says It's that third scenario, in which doctors would bill for care for uninsured patients, that could face pushback, the OMA noted in a 2024 report. "The Ministry may indicate that this is simply not their problem to manage … Some members of the public may feel similarly," the report says. Under the proposed policy, hospitals would need to make reasonable attempts to verify someone's coverage, said OMA president Dr. Zainab Abdurrahman. But if that's not possible, she believes the doctors caring for them should still get paid. "Our real focus is really the OHIP-eligible. Could someone [ineligible] slip in there? There's always a possibility," Abdurrahman said. "We're being very specific and very intentional … to help allay the fears that this is just going to be a free-for-all for everyone to come and get Ontario taxpayer-paid health care," she said. "That's not our goal." When the policy was in place during the pandemic, the OMA found that 7,000 Ontario physicians provided 400,000 instances of care to patients without insurance. Similar programs exist across Canada: OMA It's unclear whether bringing back the policy could incentivize more medical tourism, said Boriana Miloucheva, an assistant professor of health economics at the Dalla Lana School of Public Health. "The option to get medical services and not pay [the bill] already exists," she said. "It's a good-faith program, but there should be reviews about who is actually billing and what they're actually billing," she said. Other provinces, such as B.C., Alberta, Saskatchewan, and Quebec, do provide similar payment options for emergencies, according to the OMA. Some of them allow retroactive billing or accept mailing addresses from homeless shelters as proof of residency for those without a health card. A similar policy was also recently implemented in Manitoba. Ontario doctors are close to a new compensation deal. Here's what it includes 7 days ago The Ontario Medical Association is hoping to strike a new deal with the province that would change the way family physicians are compensated. CBC's Dale Manucdoc has more on what the proposed deal includes. Ultimately, says Dr. Ho, this is about more than getting compensated for work. He says it's a health equity issue for the province's most vulnerable populations, who might delay care or turn down prescriptions they can't pay for because they can't prove they're eligible for OHIP. Ho says the policy could end up saving the province money, since people postponing care could face more serious health issues that need treating later on. "We do need to reduce these barriers to care and … create fair processes for these patients because they are disproportionately affected by this," he said. Abdurrahman said she's hoping for an update on the proposed policy this fall.
