For people living with chronic kidney disease
Keep track of your eGFR without keeping a spreadsheet
Basin gathers your kidney labs from your doctors into one line you can follow, explained in plain words, so you walk into each visit knowing which way your numbers are moving.
7-day free trial, then $9 a month. Cancel anytime.
Basin is made by Triangle. You'll create your account at trianglehealth.com.
Kidney care moves slowly, and the numbers are scattered
Your eGFR is in one portal and your uACR in another. Your nephrologist orders one set of labs and your primary care doctor orders another. Your home blood pressure lives on a cuff or in an app.
So each visit starts with the same question: what was it last time? Keeping your own spreadsheet works until a result arrives on paper, or from a lab you didn't expect.
- eGFR and creatininethe nephrology portal
- uACRa different lab's report
- Blood pressurea cuff, a notebook, an app
- Medicationsthree pharmacies' worth of labels
Four steps, then it keeps itself current
- First
Start your trial
Start the 7-day free trial and say who the profile is for: you, or someone you look after, such as a parent.
- Then
Verify, sign, meet a clinician
Confirm your identity and address, sign the consent forms, and book an intake visit with a clinician, who signs the records request with you.
- Next
Your records come to you
Triangle requests them through the national health-record networks, Carequality and TEFCA. Upload anything they miss, such as a paper result or a disc, and connect a Withings cuff if you use one.
- From then on
Follow the lines, ask the questions
Each lab becomes a result you can follow over time, explained in plain language. Ask about any of it in a chat that knows your history.
Your history updates as new records arrive. Basin shows what may be missing and helps you request it.
Seven results from two practices, on one line
Results from your nephrologist and your primary care doctor land in one history, in date order. Read what each one means, and ask what has changed since a new medicine before you're in the exam room.
The numbers, dates and medication here are made up.
In plain words: eGFR is an estimate of how well your kidneys filter, calculated from a blood test. Yours has stayed between 50 and 55 across seven results.
Has anything changed since I started lisinopril?
Your records show lisinopril 10 mg starting in June 2025. Your eGFR results before that were 55, 53 and 54, and since then 50, 52, 51 and 51. Your uACR went from 52 to 31 mg/g over the same time.
What those changes mean for you is a good question for your nephrologist.
Cancel before day 7 and you're not charged.
What changes when it all lives in one place
You see which way it's moving
eGFR, creatinine and uACR from different practices become results you can follow across years, each explained in plain language.
Blood pressure sits beside them
Readings from your visits and from a connected Withings cuff sit next to your labs. Set a reminder in plain words: "Remind me every morning at 8 to take my blood pressure."
You stop retelling your medicines
Your medication list, built from your records, including pharmacy fills when the records contain them.
Questions get answered from your file
A chat that answers from your own records. A second check reviews each answer against the evidence before you rely on it.
A clinician reads your history
Membership includes a review of your medical history by a licensed clinician.
Family can help
Share your profile with family or a doctor, and choose who can see it and who can help manage it.
Your own assistant
Let Claude or ChatGPT read your kidney history
If you already use an AI assistant, connect it to Basin. With your permission it reads your labs, blood pressure readings, medications, notes and the summary of your history. If you also allow writing, it can add notes or set reminders for you.
It works only with what's in Triangle, and it can't change anything at a hospital or clinic.

- Open your assistant's settings and find Connectors, Connections or Tools.
- Add a new connection and paste the address.
- Sign in to Triangle when it asks.

Once connected, what your assistant reads is handled under its own privacy policy, which Triangle doesn't control. Connect only one you trust.
Disconnect any time in Triangle under Settings → AI service connections, and access stops immediately. Only the person whose profile it is can connect an assistant, so if you run a profile for a parent, they connect their own.
Connecting an assistant is optional. Basin works on its own.

Questions
What does it cost?
Basin starts with a 7-day free trial. You add a card when you start; cancel before day 7 and you're not charged. After that it's $9 a month, and you can cancel any month; your records stay yours. The membership covers Triangle requesting your records from hospitals and clinics and keeping them updated as new ones arrive, chat anytime with the assistant that answers from your own records, a review of your medical history by a licensed clinician, connecting wearables such as a blood pressure cuff, and uploading anything else you have.
What does setup ask of me?
After you start the trial: a few details, an identity check and confirming your address, choosing who can see the profile, signing the consent forms, and booking an intake visit with a clinician. Then Triangle requests your records, and you can upload anything else you have.
Will my nephrologist's records come through?
Triangle requests records through the national health-record networks, Carequality and TEFCA. Not every practice or lab can be reached that way, so Basin shows what may be missing and helps you request it, and you can upload results yourself: PDFs, photos of paper reports, discs or faxes.
Will Basin tell me my stage, or what to do?
No. Triangle does not diagnose, treat or prescribe, and it doesn't replace your kidney doctor. Basin shows what your records say and how your numbers have moved, so you can talk it through with your care team.
Can I connect my blood pressure cuff?
Yes. You can connect devices and services including Withings, Fitbit, Garmin, Oura and Samsung Health, and their readings sit next to your records. Blood pressure measured at your appointments shows up whenever it's in your records.
Who runs Basin, and who sees my records?
Basin is made by Triangle. Your account is a Triangle account, under Triangle's privacy policy and terms. You choose who can see your profile, such as family or a doctor, and who can help manage it. Your data is never sold or shared for advertising.
