About Bllod
A single bloodwork value is a snapshot. The trajectory is the story.
We built Bllod because that snapshot was all most people ever got. Patient portals show you one number at a time. Email keeps your PDFs scattered across providers. The lab printout from three years ago is somewhere in a drawer. There was no place to put your bloodwork down, watch it move, and actually understand what your numbers are doing.
So we made one.
What Bllod is
Bllod is the home for your blood tests. Upload a PDF, see what's changing, understand what it means.
The load-bearing piece is a PDF parser that handles 47 lab formats and counting — Brazilian and US so far, more coming. Quest Diagnostics. LabCorp. Dasa. Fleury. Sabin. You drop a panel in, and within seconds Bllod has extracted every marker — name, value, unit, reference range, date — and lined it up next to your previous panels so you can see what's actually trending.
Each marker has a plain-English explainer attached. Not a Wikipedia dump. A short, clear paragraph that says what the marker measures, what its reference range typically is, and what going up or down tends to mean. No "diagnose / treat / cure" language. No alarm bells.
Who Bllod is for
Two kinds of people, equally.
The first is the person who has had three or more blood panels in the last few years and is quietly frustrated that nothing is tracking them. They track their workouts, their sleep, their weight. They read about iron metabolism on Saturday mornings. They want the trend view their patient portal won't give them.
The second is the person who just got a result with a marker outside the reference range and is one Google search away from a panic. They don't need optimization. They need context: what does this number actually mean, how worried should they be, and what's a sensible next step.
Bllod is built for both, and we try not to lose either when we write a sentence.
What Bllod is not
We're not a doctor. We don't diagnose conditions, we don't recommend supplements, and we don't substitute for your appointment with a clinician. If a result is genuinely outside its reference range and the marker matters, we'll tell you to mention it at your next visit — which is what a friend who happens to know about labs would tell you over coffee.
We're not a wellness brand. We don't sell glow. We don't talk about "biohacking" unless the word fits. We're precise, not aspirational.
We're not B2B. Clinicians and clinics might find Bllod useful eventually. But we're a consumer product, built for you, the person looking at your own blood test results.
How we're built
Bllod is built in public by a small indie team. You can watch the actual shipping happen — every week, we post what got built, what broke, and what's next. No PR theater. No "thrilled to announce." Just the real work.
We're trilingual from day one — English, Portuguese, Spanish. Not auto-translated. The Portuguese is written by someone who actually reads PT lab reports. Same for Spanish.
The brand spelling is Bllod — blood with two L's. It's deliberate. The category is full of "MyHealth"-style names that all blur together. Ours doesn't.
What's next
The iOS app is launching imminently. The Android version follows. The blog you're reading is part of a weekly cadence — one marker explained, one trend revealed, one shipping update — running across X, Threads, LinkedIn, Instagram, and right here. Subscribe at the bottom of the page or follow us on whichever platform you live on, and we'll meet you there.
A few common questions
Is Bllod a doctor? No. Bllod is an informational tool. We translate the chart, not the appointment. Anything that looks like it needs medical attention is something to bring up with a clinician.
How do you handle privacy? Your panels and markers live encrypted on Supabase. We don't sell data. We don't share with brokers. We don't train models on your bloodwork.
Where does the marker data come from? We extract markers from your lab PDFs and match them against the LOINC standard library — the same coding system labs themselves use internally. So a marker is the same marker whether it came from Quest, LabCorp, or Fleury.
How is this different from my patient portal? Your patient portal shows you one panel at a time, locked to one provider's system. Bllod is one place for every panel you've ever had, from any lab, with the trend view drawn for you.
