Chart your blood test results over time

See every biomarker as a trend

A single result is a snapshot; a trend tells the story. BloodId plots each biomarker over time with its reference range shaded in, so you can immediately see whether a value is stable, improving, or drifting out of range.

Color-coded points and bands make outliers obvious at a glance, and you can tap any point to jump back to the original lab report it came from.

Compare results across labs

Results from different labs often use different units. BloodId normalizes US conventional units (mg/dL) and international SI units (mmol/L) to a common scale at display time, so a Quest result and a European lab result sit on the same chart without manual conversion.

Reference ranges that make sense

BloodId uses your lab's own reference range when available and falls back to ABIM standard ranges otherwise, with a clear note about which is shown. You can also set a custom range your doctor recommends.

Frequently asked questions

Can I chart results from different labs together?

Yes. BloodId normalizes US (mg/dL) and SI (mmol/L) units at display time, so results from any lab line up on the same trend chart.

Is charting my blood test results free?

Yes — viewing your biomarker trends and charts is included free once your results are uploaded. New accounts get 3 free uploads to start.

Which reference range do the charts use?

Your lab's own range when available, otherwise the ABIM standard range, with a clear disclaimer about which is shown. You can also set a custom range.

How far back can I track?

As far back as you have results. Upload older PDFs and BloodId places them on the timeline so your full history is in one chart.
