One question I hear a lot from new patients goes something like this: “My annual physical came back fine. Is there anything it didn’t check?”
It’s a good question, and the answer usually isn’t that anyone did anything wrong. A routine physical covers a core set of labs that screen for common diseases. A longevity blood panel looks further upstream, at markers of heart health, metabolism, thyroid function, hormones, and nutrient levels, some of which can change before a standard panel flags anything.
If you’re asking because you still don’t feel right despite normal results, that’s a slightly different question, and I cover it in my post on what to do when standard bloodwork looks normal but you still don’t feel right. Here’s what an expanded panel can reveal, what it can’t, and how I think about it as a physician.
Most annual physicals include a small set of standard labs:
These tests matter. They screen well for anemia, kidney and liver problems, high cholesterol, and diabetes. But they leave out several markers that can show risk earlier.
When your results come back “normal,” it means they fall within the lab’s reference range. For many tests, those ranges come from testing a large group of healthy people and keeping the middle 95% of their results (Journal of the American Board of Family Medicine). So “normal” means typical for that group. It doesn’t necessarily mean ideal for you, and a result inside the range isn’t a guarantee of good health (MedlinePlus).
That’s not a flaw in the system. Reference ranges are a useful starting point. But when I look at a panel, I’m also asking where each number sits within that range, how it has changed over time, and how it fits with your symptoms and history.
Heart disease can develop quietly for decades. A standard lipid panel shows part of the picture, and these three markers fill in more of it.
ApoB. Every particle that can carry cholesterol into your artery walls has one apolipoprotein B (ApoB) molecule on it, so ApoB works like a particle count. Studies generally find ApoB is more closely tied to heart risk than LDL cholesterol, and the difference matters most when the two disagree. That mismatch is common in people with high triglycerides, diabetes, or metabolic syndrome (Endotext, NCBI Bookshelf).
Lp(a). Lipoprotein(a) is largely set by your genes and doesn’t change much with diet or exercise. A high level raises your risk of heart attack and stroke even when your cholesterol looks fine (MedlinePlus). Because it’s inherited and stable, the 2026 ACC/AHA dyslipidemia guideline and the National Lipid Association both recommend measuring it at least once in every adult, and a level of 125 nmol/L (50 mg/dL) or higher counts as a risk-enhancing factor (American Heart Association, National Lipid Association).
hs-CRP. High-sensitivity C-reactive protein measures low-grade inflammation, and elevated levels are associated with higher cardiovascular risk (AHA and CDC Scientific Statement, 2003). It isn’t specific, though. Infections, injuries, and other inflammatory conditions can raise it too, so I always read it alongside everything else (Mayo Clinic).
I go deeper on ApoB and hs-CRP, along with fasting insulin, in my post on those three markers.
Fasting glucose and A1c tell you where your blood sugar is today. They don’t tell you how hard your body is working to keep it there.
With insulin resistance, your cells respond less to insulin, so your pancreas makes more of it to compensate. That extra insulin can keep glucose in range for years, and insulin resistance is thought to begin 10 to 15 years before type 2 diabetes develops (StatPearls, NCBI Bookshelf).
Fasting insulin, paired with fasting glucose, can offer an early clue. But there’s no generally accepted test for insulin resistance, and these measures aren’t part of clinical guidelines (StatPearls, NCBI Bookshelf), so I treat them as a signal to look closer, not a diagnosis.
When thyroid function gets checked, it’s usually with one test: TSH, the pituitary hormone that tells your thyroid how hard to work. TSH is the right first test (American Thyroid Association). A fuller panel adds detail:
Hashimoto’s can be present while your hormone levels are still normal. Knowing early means we can monitor your TSH and catch changes before they catch you (American Thyroid Association).
Hormones shape your energy, mood, sleep, body composition, and libido, but they usually aren’t part of a routine physical unless you bring up a specific symptom.
For men, a hormone panel often includes total testosterone and SHBG (sex hormone binding globulin). SHBG matters because testosterone bound to it isn’t available to your tissues, so total testosterone alone doesn’t show how much you can actually use (MedlinePlus). Low testosterone also shouldn’t be diagnosed from a single number. The American Urological Association calls for two early-morning tests on separate days, along with symptoms, before making that call (AUA).
For women, which hormones to test depends on age, cycle, and symptoms, and timing matters a great deal. This is one area where a real conversation with your provider shapes the panel more than any checklist can.
Some of the most useful findings on an expanded panel are also the simplest to act on.
| Area | Routine physical | A longevity panel may add | What it can reveal |
|---|---|---|---|
| Heart health | Lipid panel | ApoB, Lp(a), hs-CRP | Particle count, inherited risk, and inflammation |
| Blood sugar | Glucose, sometimes A1c | Fasting insulin, HOMA-IR | Early signs of insulin resistance |
| Thyroid | Sometimes TSH alone | Free T4, free T3, thyroid antibodies | Autoimmune thyroid disease while hormones are still normal |
| Hormones | Usually not included | Testosterone and SHBG, others based on symptoms | Levels that affect energy, mood, and body composition |
| Nutrients | Usually not included | Vitamin D, B12, ferritin, homocysteine | Nutrient gaps, sometimes before anemia shows up |
More data isn’t automatically better, and I’d be doing you a disservice if I didn’t say so.
Because reference ranges are built around the middle 95% of healthy people, the more tests you run, the more likely something lands outside the range by chance. On a panel of 20 tests, about 64% of healthy people will have at least one “abnormal” result (Journal of the American Board of Family Medicine). One out-of-range number is a reason to look closer, not a reason to panic.
A blood panel also can’t replace a physical exam, your history, or imaging when it’s needed. Results can shift with food and drinks, medications or supplements, hard exercise before the draw, and, for women, having a period at the time of the test. It also helps to use the same lab when you track a marker over time, since labs use different methods and reference ranges (MedlinePlus).
The value of a longevity panel isn’t the number of markers on it. It’s having a provider who can connect those markers to you.
At The Longevity Center FL, one of the physician-owned practices managed by Longevity Centers of America (LCOA), testing isn’t the first step.
We start by listening to your history, your symptoms, and what you want your health to look like ten or twenty years from now. That conversation shapes which markers we test, so your panel is built around you instead of run as a one-size-fits-all package.
When your results come back, your provider walks through them with you: what’s in range, what isn’t, and what’s in range but worth watching. Those results help shape the plan you and your provider build together, and follow-up testing shows how your numbers change over time.
If you want to know what an expanded panel would add to your last physical, schedule a consultation to talk it through.
A longevity blood panel is an expanded set of blood tests that goes beyond routine physical labs. It looks at markers of cardiovascular risk, metabolic health, inflammation, thyroid function, hormones, and nutrient status, with the goal of spotting changes early.
A routine physical usually covers a complete blood count, a metabolic panel, a lipid panel, and sometimes an A1c. Depending on your history and goals, a longevity panel may add ApoB, Lp(a), hs-CRP, fasting insulin, a full thyroid panel with antibodies, hormones such as testosterone and SHBG, and nutrients like vitamin D, B12, ferritin, and homocysteine.
It depends on your history, symptoms, and goals. An expanded panel can add markers like ApoB and Lp(a) that routine labs often skip, and current guidelines now recommend checking Lp(a) at least once in every adult. Your provider can help you decide whether the added information is likely to change your plan.
Usually just once. Lp(a) is mostly determined by genetics and stays fairly stable over your lifetime, so the 2026 ACC/AHA dyslipidemia guideline and the National Lipid Association recommend that every adult have it measured at least once.
Often, yes. Markers like fasting insulin and fasting glucose require a fast, usually overnight. We’ll give you specific instructions before your blood draw.
No. A blood panel shows where your health stands and where it may be heading, but it can’t predict your lifespan. It’s most useful for spotting risks early and tracking whether the changes you make are working.
