Health radar and AI Summary: how to read your overview

The health radar in HealthLab groups the biomarkers in your profile by category and shows each category alongside its trend — one overview instead of scrolling through results one at a time. Almost everything the radar does beyond that basic grouping — “Explain my radar,” an AI Summary of a single analysis, and custom radar dashboards — requires a Pro subscription. The Pro features described below are not available on the free tier; what you keep without Pro is covered in the “Free or Pro” section at the end.

What to do and where

Step 1. Open the radar overview

Go to the lab results section and open the radar. It’s built from whatever biomarkers are already saved in your profile — entered by hand or recognized through AI import, it makes no difference which.

Step 2. Read what the radar actually shows

The radar groups your biomarkers by category and shows each category together with its trend based on the values you’ve saved. That’s all the radar shows — no composite health score, no color-zone system, just categories and trends built from what’s already in your profile.

The practical difference from opening results one at a time is that the radar immediately shows which categories your saved history actually covers, and which it doesn’t. If a profile has a detailed lipid history going back three years but has never had a thyroid-hormone value saved, that gap is visible from the grouping itself, before any AI request is made.

Step 3. Run “Explain my radar” (Pro)

Tap “Explain my radar” — one of the two modes of the AI Summary feature. HealthLab sends de-identified biomarker data (categories, values, dates, age, sex, pregnancy status — no name) to the Google Gemini API, and gets back an overview of all the biomarkers in your profile, grouped by category, with an explanation of the trends.

Step 4. Generate an AI Summary for a single analysis (Pro)

The second mode of the same feature works at a narrower scale: open one specific imported analysis and request an AI Summary for it. Instead of an overview of your whole profile, you get an interpretation of just that one set of values — useful right after importing a new result, when you don’t want to wait for the full radar overview to catch up.

Step 5. Build a custom radar dashboard (Pro)

If the default category grouping doesn’t match what you actually care about, put together your own biomarker set for a separate radar dashboard. That keeps the markers you track regularly in one place, instead of hunting for them across every category each time.

Step 6. Turn AI features off if you’d rather not use them

The AI Summary can be disabled in the app’s Settings. That covers both modes — “Explain my radar” and the single-analysis summary. The radar itself, as category grouping with trends, doesn’t go away when you do this; only the AI interpretation is switched off.

Scenario: getting ready for a checkup

After a year and a half of using HealthLab, one profile has 24 saved biomarkers spread across six categories, from a complete blood count to thyroid hormones. Instead of opening every chart individually before a doctor’s appointment and trying to remember what’s changed since the last one, the profile’s owner opens the radar and runs “Explain my radar”: an overview of every category with an explanation of the trends comes back from one request, not fifteen separate chart views.

A week earlier, when one fresh lab result had just come in, the same person did something different: opened that one analysis first and requested an AI Summary for it specifically — to understand that single set of values right after importing it, without waiting for the full radar to catch up. The two modes complement each other: the single-analysis mode right after a new result lands, the full-radar mode right before an appointment, when seeing the whole picture matters more.

Neither step replaces the actual conversation with a doctor. Both AI Summary modes explain what’s visible in data that’s already saved and how values have moved over time — they don’t diagnose anything and don’t recommend what to do next. That makes the output something worth bringing to an appointment, not something to act on by itself.

Edge cases

• Not much saved in the profile yet. The radar groups whatever is already there; the fewer biomarkers saved, the less there is for the overview to work with — add more, either manually or through AI import.
• No internet connection. “Explain my radar” and the single-analysis AI Summary both need a connection, since the request goes to the Google Gemini API. A response you’ve already received is cached on-device for 24 hours after it was generated.
• No Pro subscription. Both AI Summary modes and custom radar dashboards are unavailable on the free tier — this is exactly where the Free/Pro line falls for this feature.
• AI features turned off in Settings. The radar keeps showing categories and trends as before; only the AI interpretation request becomes unavailable until the toggle is switched back on.
• A cached response has gone stale. Once more than 24 hours have passed since the last generation, the on-device cached response is no longer guaranteed to be available — getting a fresh overview means a new request, and that needs an internet connection.

Free or Pro

The category-and-trend radar, “Explain my radar,” the single-analysis AI Summary, and custom radar dashboards are all Pro. Being on the free tier doesn’t mean an app without anything useful here: manual biomarker entry stays unlimited on every tier, the first 3 AI imports of lab results are free to try, and biomarker trend charts — a separate feature from the radar — remain available on Free. For more on reading a single marker’s trend chart, see how to read your trend chart.

In practice, that means this: if you haven’t subscribed to Pro yet, building up a history of results and watching each one move over time is already available today, with no limit on how many values you enter by hand. The radar and AI Summary add a different way of looking at that same history — an overview, grouped by category, with the trends explained in words instead of read off a chart. It’s a layer built on top of data you’re already keeping, not a condition for keeping it in the first place.

Frequently asked questions

HealthLab: from saved results to an overview

The radar and AI Summary are both built entirely from what’s already saved in your profile, so the people who get the most out of them are the ones who save lab results regularly — by hand or through AI import; for more on reading the values themselves, see how to read your lab results. If you’re deciding which markers are worth tracking regularly in the first place, the baseline guides women’s health 40+ and men’s health 40+ are a starting point.
