What bloodwork does
Reads each value in plain words
Upload a PDF or a photo of the printout, and every value becomes a structured result explained in everyday language. The lab's reference range sits next to it.
Lines up your earlier results
Each value is placed beside the same test from your earlier reports, so one number can be followed across years. Older panels can arrive too, since Triangle asks Carequality and TEFCA for your records.
Ask about any value
Ask what a test measures or how a number has moved, and the chat answers using your records. Every reply is re-checked against the evidence in a second pass before you rely on it.
Turns a report into questions
Ask the chat to help you write down what to raise at your next appointment. Your doctor interprets what the results mean for you.
What makes bloodwork different
Results from more than one lab
A lab's portal is limited to the tests that lab performed. bloodwork sets your results beside those from other labs and from your doctors' records, each with a plain-language note.
An assistant that has read your history
Ask ChatGPT, Claude or Grok about a result without connecting your records, and it has only the values you give it. Connected to bloodwork with your permission, it can read your actual results and how they've moved.
Month to month, clinician review included
Pricing is month to month: a 7-day free trial with a card, then $9 a month that you can cancel any time. That $9 also covers a licensed clinician reviewing your medical history.
No lab pays for this
No laboratory, drug maker or hospital pays Triangle, including the lab that ran your test. Your results are never sold or shared for advertising.
Who uses bloodwork
- People whose results posted with flags before anyone talked them through
- People following one number, such as LDL, A1c or fasting glucose, across years and labs
- People preparing questions for a follow-up appointment about a result
- Family members who help someone they look after make sense of a report
The team behind bloodwork
Behind bloodwork is Triangle, legally Triangle Health, Inc., a Pasadena, California company whose founding medical advisor is Dr. Santosh Kesari, a neuro-oncologist. Triangle was co-founded by Arun Verma, its CEO, with Jonathan Grubb and Justin Balthrop, after Arun's 2023 brain tumor diagnosis sent him through his own reports line by line, researching them by hand. bloodwork turns that kind of careful reading into something anyone with a confusing result can use.

How bloodwork works
Begin with a 7-day trial
Step one is a 7-day free trial, plus a note on whose results these are: yours, or those of a person you look after.
Check-in: identity and consent
Identity check, consent forms, then an intake visit on the schedule; the clinician you meet signs the records request with you.
Add the report, then read
Upload your latest report while Triangle requests earlier results and records through the national networks. Read through your values and medication list, put your questions to the chat, and bring family in if that would help.
Optional: your own assistant
Connect Claude, ChatGPT or Grok if you'd like to ask about your results there as well. Send setup questions to Triangle's inbox, support@trianglehealth.com.

Frequently asked questions
Who is behind bloodwork, and what does it do with a lab report?
bloodwork explains your lab results in plain words and sets each value beside your earlier ones. Triangle makes it; you'll sign in with a Triangle account.
What's the price of bloodwork?
A 7-day free trial comes first, and a card is required to start it. Once the trial wraps up, bloodwork charges $9 a month until the day you cancel.
Is bloodwork a doctor reading my results?
No. It provides research and educational support, and Triangle built it so that it does not diagnose, treat or prescribe. What a result means for you, and what to do about it, is your clinician's call.
Can Claude, ChatGPT or Grok read the values bloodwork holds?
Yes. Add https://app.trianglehealth.com/mcp to your assistant as an MCP server; on Triangle's consent screen you then switch on the kinds of results it can read. trianglehealth.com/agents has a walkthrough for Claude, ChatGPT and Grok.
Is my bloodwork safe, and who else sees it?
In transit and at rest alike, every value stays encrypted, and Triangle handles it as a HIPAA-compliant company. Not one value is sold or shared for advertising, and you approve who can open your profile.
Can I use a report from any lab?
Yes. Upload a PDF or a photo of a printed report from whichever lab ran the test. Triangle also requests your records through the national networks, though not every lab or clinic can be reached that way.
What if a result worries me?
Call your doctor or the office that ordered the test, and if it feels like an emergency, call 911. bloodwork is for understanding your results and never replaces your care team.
What do the H and L flags mean?
H or L means a value sits above or below that lab's reference range. What it means for you depends on your history, which is why bloodwork sets each result beside your earlier ones and leaves the interpretation to your doctor.
