A genetic score is only as honest as its variant coverage and evidence map. Missing calls must never be mistaken for low risk.
Body Insights maps supported imported variants to trait rules and aggregates only covered evidence into category views. Categories with no covered variants are excluded from the headline rather than treated as reassuring. These pages describe predisposition, not destiny.
What does DNA health insights mean?
The result summarizes supported variant associations within a defined category. It cannot tell whether a trait is present, absent, or clinically significant on its own.
The useful question is not whether one reading is perfect. It is whether the same signal keeps moving in a way that matches your sleep, symptoms, activity, and recovery. Body Insights keeps the underlying rows visible so the headline never has to stand alone.
What goes into the calculation?
Body Insights reads the available inputs from Apple Health and the app's own history. It does not create missing wearable measurements.
- Successfully imported and normalized genotype calls
- The active production variant-to-trait evidence configuration
- Category coverage, effect direction, and no-call handling
Supported calls are matched to the active production rules before category and archetype summaries are produced. Only categories with covered variants contribute to the headline; uncovered categories are omitted rather than scored as optimal.
What happens when data is missing?
An absent or unrecognized variant is unknown. It must not contribute the same reassurance as a supported non-risk call.
This matters because "not measured" is not the same as "bad." A watch charging overnight, an incomplete Health permission, or a short history can reduce what the calculation knows without saying anything negative about your body.
What can change the result?
A different raw-data file, improved parser coverage, revised evidence rules, and newly supported variants can change category results.
If a result looks surprising, check the input rows first. A single missing night, unusual workout, illness, medication change, travel day, or sensor gap can explain more than the headline number.
What can this calculation not tell you?
Consumer genotype interpretation cannot diagnose disease, replace clinical genetic testing, or account for every variant, environment, ancestry, and interaction.
Body Insights is a pattern-reading tool, not a diagnostic device. Bring persistent, severe, or worrying changes to a qualified clinician, especially when the number and how you feel disagree for several days.
Read the reason, not only the number
Check coverage before the score. Discuss consequential findings with a qualified genetics professional rather than changing treatment from an app result.
Body Insights reads data that Apple Watch and compatible devices place in Apple Health. The purpose of this page is to make that translation inspectable without publishing gameable score weights or pretending a wearable estimate is a clinical test.
