Labs & biomarkers

Connect the dots.

Your labs show where you stand once or twice a year. Your habits decide where you’ll be. Protocol puts your bloodwork next to your sleep, steps, training and food, so you can see what’s moving the numbers that matter.

Free to start, no credit card. Your first lab draw is free; Pro adds every draw after it.

How does Protocol connect your labs to your daily habits?

Protocol reads lab results from any lab, as a PDF or screenshots, and keeps every marker across every draw in one place. It sets each marker beside the daily data that moves it: your sleep, steps, zone 2 minutes, workouts and protein from your wearable and the meals you log. For every marker with two draws, it shows your average habits in the 90 days before each one, and it turns out-of-range markers into daily goals you can track.

Why it matters

Chronic disease is built daily. We check on it yearly.

Most chronic disease grows out of the same short list of daily habits: how much you move, sleep and eat, and what. But you only see it in your labs once or twice a year, as a list of numbers with nothing to tie them to the months that produced them.

Lagging numbers.Leading habits.

Labs tell you where you’ve been. Your habits are where you’re going. Five ways Protocol puts them together.

Bring your labs

From any lab.
In a minute.

Function Health, Quest, Labcorp, your primary care doctor: if it gives you a PDF or a results screen, Protocol can read it. Every marker, value, unit, range and draw date lands in one place.

  • Upload the PDF, or up to six screenshots, on the web or your iPhone.
  • Your first draw is free. With Pro, bring every draw, older panels too: each one adds a point to every marker’s history.
  • Not sure where to get tested? A short guide covers full panels, at-home kits and single tests, and how to download each one’s results.
  • Protocol keeps the values, not the document: the file and its full text are never stored.

Every draw.

Your markers from every lab and every year sit on one page, newest first, with what moved since last time and what needs attention most.

  • What’s out of range, furthest outside your lab’s range first.
  • What came back into range, and what newly went out, since your last draw.
  • Plain-language explanations for 75 common markers: what it measures, why it matters, what moves it.
  • A nudge to retest once your latest draw is six months old.

Know what moves it

The habits
behind the numbers.

A marker on its own is a verdict. Protocol turns each out-of-range one into the daily habit most likely to move it, and makes that habit a goal you can track.

  • Lab-based goals: high LDL or triglycerides point to zone 2 minutes, high glucose or A1c to zone 2 and protein, low vitamin D to time outside on your feet.
  • Each suggestion says why, in plain language, and becomes a daily or weekly target with one tap.
  • The coach’s read of your panel: what’s working, what to watch, and one thing to do this week.
  • Never a diagnosis. When a result belongs with your doctor, Protocol says so.

Your labs, every day

Your labs
in today’s plan.

Your labs don’t sit in a drawer until next year. The morning brief and the coach read them with your sleep, training and food, so a lab result shapes what you do today.

  • The brief ties one out-of-range marker to today’s moves: an elevated A1c becomes a 10-minute walk after dinner.
  • Ask the coach about any marker (Pro) and it answers with your history and your habits, not a textbook.
  • It never leads with labs or lists them back to you. It just makes today’s advice fit them.
  • With Pro, everyday coaching adapts to your markers even when you didn’t ask about labs.

Between your draws

See what
moved them.

This is where the dots connect. For every marker with two draws, Protocol shows how it moved next to your own habits in the 90 days before each one. Part of Pro, since it needs a second draw.

  • Your average steps, zone 2 minutes, workouts, sleep and protein before each draw, side by side.
  • Each marker shows the habits that matter for it: aerobic work next to lipids and A1c, sleep next to inflammation, steps next to vitamin D.
  • Changes are marked when they’re real (10% or more), so noise doesn’t look like progress.
  • It shows what changed alongside a marker, not what caused it. Diet, medication and genetics count too.

Your gut,
in the same picture.

Gut health is in preview with a small group of members. Bring a stool test and see it next to everything else: your diversity, the bacteria worth watching, what your gut is equipped to do, and how the fiber you log lines up with it.

  • Diversity and balance

    How many species you carry and how evenly, from one sample.

  • What your gut can do

    Capacities like making butyrate, next to the fiber in your meal log.

  • When to test again

    Gut results shift with diet, so a retest a few months in shows what changed.

The evidence

Habits move markers. Slowly, then clearly.

The research on lifestyle and long-term markers points one way: what you do most days shows up in your bloodwork months later. What each study found, and where it shows up in Protocol. It supports the approach; it is not evidence of Protocol’s own outcomes.

  • Changing daily habits beat a drug at preventing diabetes.

    In the Diabetes Prevention Program, 3,234 adults with elevated blood sugar were randomized. A lifestyle program of activity and modest weight loss cut new cases of diabetes by 58% over about three years, against 31% for metformin, both compared with placebo.

    In Protocol: Lab-based goals for glucose and A1cKnowler et al., 2002, New England Journal of Medicine

  • Four everyday habits, far less chronic disease.

    Among 23,153 adults in a German cohort, those who never smoked, kept a BMI under 30, were active at least 3.5 hours a week and ate a healthy diet had a 78% lower risk of developing a major chronic disease than those with none of the four. An association in an observational study, not a trial.

    In Protocol: Your daily rings and goalsFord et al., 2009, Archives of Internal Medicine

  • Structured exercise lowers HbA1c.

    Across 47 randomized trials in type 2 diabetes, structured exercise training lowered HbA1c by 0.67 percentage points, and more than 150 minutes a week did more than less. Advice to be active, on its own, did not.

    In Protocol: Zone 2 and workouts next to A1cUmpierre et al., 2011, JAMA

  • Aerobic exercise raises HDL, modestly.

    Pooling 35 randomized trials from 25 studies, regular aerobic exercise raised HDL cholesterol by about 2.5 mg/dL, with about 120 minutes a week as the smallest effective dose. The authors call the effect modest.

    In Protocol: Zone 2 next to your lipidsKodama et al., 2007, Archives of Internal Medicine

  • Exercise training lowers inflammation.

    Across 83 controlled trials, exercise training lowered C-reactive protein by a small but consistent amount, more so when it came with weight loss.

    In Protocol: Sleep and zone 2 next to hs-CRPFedewa et al., 2017, British Journal of Sports Medicine

  • HbA1c is a three-month average.

    The A1C test reflects your average blood sugar over about the past three months, which is why habits show up in it months later, and why a retest a week after changing them tells you little.

Lab questions

Asked and answered.

How do I connect my lab results to my daily habits?

Put your labs and your daily data in the same place. In Protocol you upload any lab PDF or screenshots, and your sleep, steps, training and food come in from your wearable and the meals you log. For each marker with two draws, Between your draws shows how it moved next to your average habits in the 90 days before each one, and lab-based goals turn out-of-range markers into the daily habits most likely to move them.

Can I upload lab results from Function Health, Quest or Labcorp?

Yes. Protocol reads lab reports from any lab, including Function Health, Superpower, InsideTracker, Quest, Labcorp and your doctor’s office. Upload the results PDF or up to six screenshots of your results on the web or your iPhone. There are no direct connections to labs yet, so results come in by upload.

What does Protocol do with my lab results?

It pulls out every marker with its value, unit, reference range and draw date, then shows your markers across every draw: what’s out of range, what changed since last time and what each marker means. It suggests daily habits that tend to move out-of-range markers, shows your habits before each draw, and with Pro the coach factors your labs into everyday advice.

Why do daily habits matter for long-term biomarkers?

Most long-term markers are slow summaries of daily behavior. HbA1c reflects about three months of average blood sugar, and lipids, inflammation and blood pressure respond to activity, sleep, diet and weight over weeks to months. That makes labs the lagging indicator and daily habits the leading one: by the time a marker moves, the habits that moved it are months old. Protocol puts both side by side.

Does Protocol use optimal ranges?

Protocol shows your lab’s own ranges. When your lab reports optimal bands, as Function Health does, those appear too. Protocol doesn’t apply ranges of its own yet.

Is my lab data private?

Protocol stores the biomarker values it reads, not the document. The file you upload and its full text are not kept. Lab reports are read by an AI model that does not train on your data, and Protocol never sells your data. The privacy policy covers the details.

Does Protocol diagnose anything from my labs?

No. Protocol explains what each marker measures, shows how it has changed, and suggests everyday habits that tend to move it. It does not diagnose conditions or recommend medication, and it tells you when a result is one to take to your doctor.

How often should I get my blood work done?

That’s a decision for you and your doctor, and it depends on your results and history. Many people retest every 6 to 12 months, and sooner while working on an out-of-range marker, since changes in habits take two to three months to show in markers like HbA1c. Protocol nudges you once your latest draw is six months old.

Does Protocol support gut microbiome tests?

Gut health is in preview with a small group of members: stool test results from a PDF, diversity, what your gut bacteria are equipped to do, and how your logged fiber lines up with it. It isn’t open to everyone yet.

Is lab tracking in Protocol free?

Your first lab draw is free, with no credit card: every marker explained, lab-based goals and the coach’s read of your panel. Protocol Pro adds every draw after that, so you get each marker’s history and Between your draws, plus a coach you can ask about any marker and a morning brief that ties your labs to today. Pro is $12.99 a month or $99.99 a year.
