Export lab results as a PDF for your doctor: step by step

HealthLab can turn your lab results into a single PDF right before a doctor’s appointment: one report, several reports combined, or a trend chart for one biomarker. The file is generated on your device in a few seconds, and the feature is free with no limit. From there, “Share results” hands the file off however you’d normally share a file on your phone.

The idea is simple: instead of scrolling through the app during the appointment or printing every report separately, you prepare one file ahead of time with exactly the data this particular visit needs, then hand it to the doctor the same way you’d share any other document from your iPhone.

What to do and where

Step 1. Choose what to export

Open “Lab results” and decide what the appointment actually needs: one specific report, several results from a period combined into one file, or a trend chart for a single marker when the point is the direction it’s moving, not one number. All three live in the same place, and none of them sits behind a paywall. If the doctor specifically asked to “see how it’s been moving,” the trend chart is the right choice; for a single recent result, one report or a few combined is enough.

Step 2. Generate the PDF on your device

Tap export, and HealthLab builds the PDF locally, on your iPhone. It takes a few seconds and does not need a connection — the file is assembled from data already saved in the app, nothing extra has to be fetched first. It works the same way any other document generated on-device would: the building happens on the phone itself, not on a server somewhere.

Step 3. Check what actually made it into the file

Before handing the PDF off, open it and look at what’s inside: the report or reports you picked, or a trend chart with its dates and values. If the period or the marker isn’t the one you meant, go back to step 1 and generate a new PDF with the right selection rather than editing the file itself. It’s faster to catch a wrong selection here than to discover it mid-appointment.

Step 4. Share the results

Tap “Share results” to send the finished PDF onward, the same way you’d share any other file from your phone. Where the file goes after that is a decision made outside the app — HealthLab’s part ends at handing the PDF to that step. The same file can be shared the night before an appointment or right there in the exam room, whichever the visit calls for.

Step 5. Bring the PDF to the appointment

Once the file has been shared or saved, it’s ready for the visit the same way a printed lab slip would be — except it can hold several results or a full trend chart at once, instead of just the last single number. The doctor doesn’t need to scroll through your phone or sort through several loose papers; the relevant context is already in one file.

Scenario: an endocrinologist appointment

A patient had her TSH checked four times over 14 months — every time her levothyroxine dose changed, her doctor asked for a follow-up test 6 to 8 weeks later. Instead of carrying four separate lab slips or scrolling through the app during the appointment, she opens the TSH trend chart for the full period and exports it as one PDF. At the visit, the doctor sees all four values on a single chart at once — how the number moved after each dose adjustment, not just the latest figure.

Without that chart, the alternative is either four separate paper results from different lab visits, or reciting numbers from memory — both convey the trend the doctor actually asked for less clearly than one chart does.

The same approach works for any marker a doctor is tracking over repeat visits, not only TSH: cholesterol after a diet change, glucose during a therapy adjustment, ferritin during a long course of iron. In each of these, the value is in the line, not one number — and a trend chart carries that in a single file instead of several separate slips.

Edge cases

• You want to show a doctor whether medication was taken consistently. PDF export covers lab results and trend charts; medication intake history is not part of it. If a doctor asks about adherence, show that directly in the app instead.
• No internet connection. Generating the PDF happens entirely on-device and needs no connection; a connection may only come into play at the sharing step, depending on how you choose to send the file.
• You need a wider date range than what’s shown by default. Change the period on the trend chart itself before exporting — see how to read a trend chart for more on that.
• The result isn’t saved in the app yet. It needs to be imported or entered first — PDF export works with data that’s already there, it doesn’t create a new entry.
• You need results from different dates in one file. That’s exactly what the combined export of several results is for — there’s no need to generate a separate PDF per date and assemble them yourself.

Free or Pro

PDF export is entirely Free: a single result, several combined, and a trend chart can all be exported with no subscription and no limit on how many times. It’s a basic feature, unrelated to the paid capabilities around AI recognition or personalized norms — those govern how data gets into the app and how it’s interpreted, not how it leaves the app for a doctor to see.

That split is worth noticing precisely because it’s easy to assume otherwise: getting a result into HealthLab faster, through AI recognition, is where the paid tier applies; getting an already-saved result out again, as a PDF for a doctor, never is. Nothing about export scales with a subscription — the same export is available whether a result was typed in by hand or recognized from a photo.

Privacy: where the PDF gets built

The PDF report is built locally, on your device — nothing is uploaded anywhere during the export itself. That’s specific to export: lab results get into the app through a different path (manual entry, or AI recognition of a photo or PDF), and it’s that step, not export, where a report image briefly passes through a proxy to the recognition service.

The PDF itself is an ordinary file, and once you’ve shared it through “Share results,” where it goes from there is your decision, not something the app controls. It’s worth sharing it only with people you trust with medical data, the same way you would a printed lab slip.

The app is not a medical device and does not provide medical advice, diagnoses, or treatment recommendations — PDF export only organizes data that already exists for a conversation with a doctor, it does not interpret it. What a specific value in the exported file actually means is a question for the doctor, not for the PDF itself.

Frequently asked questions

HealthLab before a doctor’s visit

The combination that works best: make sure the values themselves are clear and checked before exporting — how to read your lab results covers that in more depth, and if the appointment is specifically about kidney function, the kidney function tests guide is worth reading beforehand too.

For the full list of what results and trends can be saved and exported, see the lab results page. It’s worth generating the PDF ahead of time rather than in the waiting room — that leaves room to check that the file actually contains the period and the marker the appointment is about.
