Import Function Health PDF Results into Health3 — Track Beyond Membership

Why Function Health members track results in Health3 too

Function Health and Health3 are complementary, not competing, services. Function provides the testing service: the panel design, the Quest Diagnostics blood draw, the lab analysis, and a clean interface for reviewing your latest results. Health3 is a long-term tracker and visualisation layer for biomarker data from any source. Many people use both: Function for the annual draw, Health3 for the multi-year history, the day-to-day cross-referencing, and the export to share with a clinician.

There are five practical reasons Function members add Health3 alongside their membership. First, longitudinal tracking that outlives any single subscription. If you ever pause, switch, or stop your Function membership, your historical numbers still live on your device and in your Health3 account. Second, portability across providers. If you supplement Function with a one-off panel from LabCorp or a separate Quest requisition, all of those results sit in one place rather than fragmenting across apps.

Third, a private, single-profile account that gives you full control of your own history rather than fragmenting it across multiple services. Fourth, multilingual interfaces in 25 languages, which matters if your household is bilingual or you discuss results with a clinician outside the US. Fifth, offline access — your imported PDFs and parsed biomarkers stay readable on your phone whether or not you have Function's app open, making Health3 useful as a quick reference at appointments.

How to download or export your Function Health PDF

Health3 imports your Function Health results from a PDF you download yourself. We do not connect to Function Health through an API, and we never ask for your Function login credentials. The export is something you do once per round of results, directly inside Function's own interface.

The general flow on most Function Health releases looks like this:

1. Open the Function Health app or sign in to the Function Health web dashboard.
2. Navigate to your latest results or test report.
3. Look for a download, export, share, or PDF option — Function typically provides a printable or downloadable report of your lab work.
4. Save the PDF to your phone, cloud drive, or computer.

Function periodically updates its app, so menus and labels can move. If you cannot find the option, Function Health's own help centre is the best source of current step-by-step instructions. Once you have the PDF saved, the rest happens inside Health3.

How Health3 reads your Function Health PDF

Inside the Health3 app, choose to add a new test result and select the PDF. Health3 supports multi-page PDFs up to 100 MB, so a long Function report with dozens of biomarkers across several pages can be imported in a single submission. You can also import images of printed pages, manually enter individual values, or pull in clinical records via Apple Health if you happen to have any results stored there.

Health3's OCR engine uses layered recognition steps so that biomarker names, numeric values, units, reference ranges, and collection dates are matched up correctly even when Function's report layout shifts between releases. The parser supports lab reports in 25 languages, and recognised biomarkers are mapped onto Health3's library of 180 supported biomarkers wherever there is a match.

Once parsing is complete, Health3 presents the extracted values for you to review before saving. You can edit anything that looks off — a misread decimal, a swapped unit, a date that imported incorrectly — and confirm. The corrected entry is then stored as a regular test result, indistinguishable from a panel imported from any other provider.

What happens after your Function Health results are in Health3

The first import becomes a baseline. Each individual biomarker is shown with its current value, the reference range from your Function report, and a category such as metabolic, lipid, hormonal, or thyroid. You can tap any biomarker to read its plain-language explanation, see what factors influence it, and pin it as a favourite for quick access from your dashboard.

From the second import onward — your next Function panel a year later, or a separate test from another lab in the meantime — Health3 starts producing time-series views. Each biomarker becomes a line chart with your historical points overlaid against the reference range, so you can see at a glance whether values are drifting up, drifting down, or holding steady. Where Health3 has multiple results for the same biomarker, the journey-aware AI insights can summarise the pattern in plain language.

You can also export a clean PDF of your trends to bring to a clinician. This is particularly useful for Function members whose primary care provider is outside the Function ecosystem: rather than printing a single report, you can hand over a chart of how, say, ApoB or fasting insulin has moved across two or three Function panels and any other tests you've added.

Privacy and data handling

Health3 is GDPR-compliant and treats lab results as sensitive personal data. Authentication is handled via email and password, Apple Sign-In, or Google Sign-In, and subscription billing runs through RevenueCat for users who choose the paid tier. Health3 does not make HIPAA compliance claims, and the app is not a covered entity under US healthcare law — you are uploading your own report to your own account, the same way you might store it in a personal cloud drive, and you remain in control of who else sees it.

When you want to share results with a family member or clinician, you can export a clean PDF directly from Health3. The exported file is a one-off document you control. Health3 does not provide medical diagnoses, does not perform telehealth consultations, does not ship at-home test kits, and does not run genetic testing — it is purely a tracker for results you already have.

Combining Function results with results from other labs

One of the strongest reasons to use Health3 alongside Function Health is that Health3's PDF and image import is format-agnostic. The OCR pipeline does not care which provider issued the report. Function Health uses Quest Diagnostics for its draws, so methodology may overlap with separate Quest panels you have ordered. You can also bring in LabCorp reports, hospital lab printouts, or panels from other services, and they all stack onto the same biomarker timelines.

If you switch testing routes, your historical Function data remains useful as the early portion of your trend. If a clinician orders an interim panel between your annual Function draws, you can drop the new PDF into Health3 and see how it slots into the existing curve. If you've been tracking blood work for years before Function existed, older PDFs extend your timeline backward.
