Lab Results Tracker
Log lab markers over time with reference range bands.
Overview
The Lab Results Tracker is a longitudinal log for any blood, urine, or panel marker your clinician runs. Markers such as HbA1c, total cholesterol, LDL, HDL, triglycerides, vitamin D, ferritin, thyroid panels, and liver enzymes all live in one chart-and-table view per marker, with optional reference ranges that turn a wall of numbers into a visual sense of in range or out of range.
Annual physicals produce a snapshot; the value of a marker arrives from the trend across years. Logging your lab results into a single record means the next time your LDL ticks up or your vitamin D drops below the reference range, you can see whether the change is a one-off or a consistent drift, and arrive at appointments with context rather than a single isolated number.
How it works
Each entry captures the test date, marker name, value, unit, and optional reference low and high values. Once you log a second value for the same marker, the tracker groups them and renders a small sparkline; if reference bounds are set, a shaded band shows the normal range, and out-of-range points draw in a warning colour so they jump off the chart.
Markers are grouped case-insensitively so "HbA1c" and "hba1c" line up. The source field lets you tag where the result came from (Quest, LabCorp, a specific clinic) which matters because reference ranges vary between labs. Notes accommodate context such as fasting state, time of day, or recent medication changes that could affect interpretation.
Examples
- Lipid panel: log total cholesterol, LDL, HDL, and triglycerides every six months and watch each marker as its own chart with reference bands.
- HbA1c trend: track quarterly values to see whether lifestyle changes are moving the long-term average glucose in the right direction.
- Thyroid management: log TSH, free T4, and free T3 over years of dose adjustments to map the relationship between dose and lab response.
- Vitamin D supplementation: chart the response to a new dose by logging values at the recommended retest interval.
FAQ
Do I need to fill in reference ranges? No. Without ranges the chart shows the trend but skips the shaded band and the in-range flag. Adding ranges is recommended because they vary by lab and by individual demographic.
How does the chart handle very different units? Each marker has its own chart scoped to its own scale, so HbA1c in percent and ferritin in nanograms per millilitre never share an axis.
Should I trust the in-range flag? Treat it as a visual aid. Your clinician's interpretation considers the trend, the context, and your overall picture, not just whether a single number sits inside a band.
Can I log a marker my lab does not use? Yes. The marker name is free text, so anything from omega-3 index to ApoB to homocysteine works the same way.
What happens if I edit a reference range later? Updating a range affects only the entries you change; older rows keep their original recorded range so historical interpretation stays intact.
