MedTrail

Your lab results. One clear history.

Different labs, countries and years. One clear history. I’m building MedTrail so you can see the bigger picture before your next appointment, without searching through dozens of PDFs.

Sound familiar?

A new doctor. Years of results. Where’s the full picture?

01

Results in ten PDFs, three languages

Sanitas, Quirón, a lab back home, a German clinic — every report in a different format, folder, and inbox.

02

You moved — the history stayed behind

New country, new doctor, no continuity. Nobody has the five years of numbers that show where you're heading.

03

The doctor sees one snapshot, not the trend

A single result looks fine. The three-year climb is the thing worth talking about — and it's invisible.

The plan

What I’m building.

  1. 01

    Collect your past reports

    No repeat blood work: the idea is to use the reports you already have. I plan to start with PDF lab reports, and I’ll confirm the exact list of supported formats for the first version.

  2. 02

    See how your results change

    A metric should land on one timeline together with the reference range printed in that same report — so years and labs read as one history instead of a stack of paper.

  3. 03

    Prepare for the doctor

    I want the history to turn into a short list of questions for your appointment. That is preparation for a conversation with your doctor — not a diagnosis, and not a substitute for one.

The concept

What I want this to look like.

Your metrics over time, the numbers behind them, and the doctor conversation it sets up. Below is a drawing of that idea, not a working application.

Sample record · never a diagnosis

LDL rose across three years — worth a review?

2022 ES 3.1 → 2023 ES 3.5 → 2024 DE 3.9 mmol/L

Vitamin D low — supplement or re-test?

48 nmol/L · ref 75–125 · Labor Berlin, 2024

Ferritin near the low edge — check iron?

31 µg/L · ref 30–200 · down from 58 in 2022

Total cholesterol crossed the reference ceiling for the first time in 2024.

5.4 mmol/L · ref 3.0–5.0 · first exceedance in 7 tests

MedTrail prepares you for the conversation. The decisions stay with your clinician.

Who’s building this

I’m building MedTrail for myself first: I want my lab reports in one place, with a clear history over time. Now I’m finding out whether others need it too. If that sounds useful, leave your email.

Aleksei Semerikov [email protected]

Price & sign-up

Want to try it when it’s ready?

€49 a year · planned price

Leave your email and I’ll tell you about the first version. No payment, no commitment.

I write once, when the first version is ready.
What exactly is stored, and how to delete it

The sign-up also stores the language, offer version and UTM campaign labels from the link, when present, to measure which campaigns bring sign-ups. They are deleted with the sign-up.

This is about the sign-up only. Aleksei Semerikov is the data controller. Your email — and your country, if you give one — are stored on the basis of your consent, and used to write to you once about the first version. No newsletter, nothing passed to anyone. Sign-ups live in a Cloudflare D1 database I have access to, and I delete them after 12 months at the latest. For a copy, a correction, deletion, a transfer, or to withdraw consent — email [email protected]. You may also lodge a complaint with a data protection supervisory authority.

Good to know

Questions people ask first.

Can I use it now?

Not yet. The product is in development. Right now I’m collecting sign-ups to find out whether anyone besides me needs it.

Is that a working interface?

No. The page shows a concept built on fictional data — a drawing of how I want it to look.

When does it launch?

No date has been announced. I won’t promise a deadline I can’t guarantee.

What will it cost?

The planned price is €49 a year. That is an indication: a sign-up is not a purchase and does not lock in a price.

Do I need to send my lab results?

No. No medical documents are needed to sign up — just your email and country.

What happens to my email?

It is stored so I can write to you once, when the first version is ready. No newsletter, nothing shared with third parties; deletion takes one email. Details sit next to the form.

Is this medical advice?

No. The idea is to put your lab history in order and help you prepare for a conversation with your doctor. No diagnosis, no treatment.

Your lab results already exist. They just need one history.

If you’d find this useful too, leave your email and I’ll tell you when it’s ready to try.
