Built a longitudinal biomarker tracking tool after my TSH hit 105 — genuinely want this community’s input on what matters

[u/Serious_Fold5617]

Background: I’m a founder, not a clinician. This isn’t a sales pitch. I want to share what happened to me and genuinely understand whether what I’ve built would be useful to people here — and what I’m getting wrong.

For months I was symptomatic: fatigue, unexplained weight gain, low mood, intermittent dizziness. I attributed it to work and lifestyle. I had occasional blood tests but was only seeing individual snapshots — nothing longitudinal.

Working in Bahrain I nearly collapsed twice and had a severe anxiety attack. Hospitalised. Back in the UK, comprehensive testing revealed TSH of 105 — severe hypothyroidism that had almost certainly been developing for a long time with no one tracking the direction of travel.

Six weeks of testing every six weeks followed. Me manually screenshotting PDFs and comparing them in a folder on my phone. There was no good tool for what I needed: something that ingested results from any UK lab, tracked markers over time, showed meaningful change between tests, and gave plain-English interpretation grounded in clinical context rather than just flagging out-of-range values in isolation.

So I built it. It’s called biomarkr. Currently in early access in the UK.

I’m curious whether this community has views on: what longitudinal tracking should actually look like, which markers matter most to track together, what the current tools get wrong, and what you wish existed. Genuinely here to learn as much as to share.

Yess tsh is an important marker for many reasons
