Free to start. Northstar explains and organizes, it does not diagnose.
Your annual blood panel
March 2026Vitamin D is a little low
Below rangeVitamin D supports your bones, muscles, and immune system. Yours is about 8 points under the usual range of 30 to 100 ng/mL.
Worth asking your doctor
My vitamin D came back low at 22 ng/mL. Is that something we should address?
A lab report you cannot read
Your results come back as a wall of abbreviations and reference ranges, scattered across portals and printouts. Understanding your own health should not require a medical degree.
The numbers are a code
Your results come back as a wall of abbreviations, reference ranges, and up and down arrows. Nobody explains what any of it means for you, so a normal result and a worrying one look almost the same.
It is scattered everywhere
Labs live in one portal, your last physical in another, a printout in a drawer. Seeing how a number has moved over years means logging into three places and squinting.
The visit goes fast
You get a few minutes with your doctor and forget half of what you meant to ask. The results you did not understand quietly become the results you never bring up.
Three steps, from numbers to understanding
No forms and no jargon. Add what you have, and Northstar does the reading, the trends, and the visit prep.
Add your labs, vitals, and how you feel
Type your values, paste a report, or upload the PDF. Add a vital or a note about how you have been feeling. No forms, no jargon.
Northstar explains each number and shows trends
Every value comes back in plain English, with its reference range, whether it is in or out of range, and how it has moved over time.
Walk into your visit prepared
See the points worth raising with a doctor, and bring a clean, shareable summary so the appointment starts from what actually matters.
From a wall of numbers to a clear picture
This is real and runs right here. Pick a sample panel, then switch between the plain-language explanations, the trends, the points worth discussing, and the visit summary. Northstar builds the same view from your own results.
Annual blood panel

Ferritin
30 to 300 ng/mL
This is illustrative sample data. Northstar builds the same plain-language view from your own results.
Most of your panel looks steady and in range, including your blood sugar and thyroid. Two things are worth a closer look with your doctor: your vitamin D is a little low, and your LDL cholesterol is above the usual range. Your iron stores also sit on the low side.
Vitamin D, 25-OH
Usual: 30 to 100 ng/mL
22ng/mL
Below rangeVitamin D supports your bones, muscles, and immune system. Yours is a little low, about 8 points under the usual range. That is common and usually easy to talk through with your doctor.
Up from 19 ng/mL a year ago, so it is moving in the right direction but still low.
LDL cholesterol
Usual: under 100 mg/dL
128mg/dL
Above rangeLDL is often called the less helpful cholesterol because higher levels can build up in blood vessels over time. Yours is above the usual target of under 100.
Up from 118 mg/dL last year.
HDL cholesterol
Usual: over 40 mg/dL
61mg/dL
In rangeHDL is the helpful cholesterol that helps carry other cholesterol away. Higher is generally better, and yours is comfortably in a good range.
About the same as last year.
Triglycerides
Usual: under 150 mg/dL
90mg/dL
In rangeA type of fat in your blood that your body stores for energy. Yours sits well within the usual range.
Hemoglobin A1c
Usual: 4.0 to 5.6 %
5.4%
In rangeThis is your average blood sugar over about the last three months, in one number. Yours is within the usual range.
Unchanged from last year.
Glucose (fasting)
Usual: 70 to 99 mg/dL
92mg/dL
In rangeA snapshot of your blood sugar after not eating for a while. Yours is in the usual range.
TSH
Usual: 0.4 to 4.0 mIU/L
2.1mIU/L
In rangeThe usual first check of how your thyroid is working. Yours sits comfortably in range.
Ferritin
Usual: 30 to 300 ng/mL
18ng/mL
Below rangeFerritin reflects the iron your body has in storage. Yours is below the usual range, which is worth mentioning, especially if you have been feeling tired.
Down from 26 ng/mL last year.
Everything to make your numbers make sense
Clear, useful, and yours. Understand every value, watch the trends, and walk into your next visit prepared.
Plain-language lab and vitals explanations
Every value explained in a sentence or two, with its reference range and whether it is in or out of range. No abbreviations, no guessing, no diagnosis.
Gentle trends over time
See how a number has moved across every result you have added, drawn as a calm line, not a wall of tables.
Doctor-discussion prep
A short list of the points worth raising, each tied to a value in your own results.
A shareable visit summary
One clean page you can hand to your doctor or export as a PDF, in plain language.
Secure and private
Your health data is encrypted, never sold, and yours to export or delete at any time.
Model-agnostic AI
Northstar routes across the best available language models and is never locked to one vendor. Your picture, not one model.
Reading your labs is the product
Turning dense lab panels and messy self-reported data into accurate, calm plain English is only possible with modern language models. That is why AI is the core of Northstar, not a bolt-on.
Reading labs is a language problem
Lab panels and self-reported notes are dense, inconsistent, and deeply human. Turning them into plain English that is accurate and calm is only possible with modern language models, so the AI is the core of Northstar, not a feature bolted on.
From a wall of numbers to a clear picture
Northstar reads a full panel, explains each value against its reference range, connects it to your earlier results, and surfaces what is worth a conversation, the work that used to fall entirely to you.
Model-agnostic by design
A thin routing layer picks the right model for the task and can move as models improve. Northstar is not tied to one provider, and every explanation records which model produced it.
A clinician decides. Northstar helps you understand.
Northstar does not diagnose, it never gives medication or dosing guidance, and it never changes your care. It explains, organizes, and helps you prepare. If a value or a note looks urgent, it shows a calm note to seek care right away.
Numbers that finally make sense
Illustrative stories from the people Northstar is built for.
For years my results were just green and red arrows I did not understand. Northstar told me my vitamin D was a little low and what that meant, in a sentence. I finally understand my own bloodwork.
Priya S.
Uses Northstar for her annual panels
I track my dad's labs from two states away. Seeing his A1c trend in plain language, and walking into his appointment with the questions already written down, took the worry down a notch.
