The verdict

These are close picks. Both score in the same range. The right call depends on buyer profile — read the per-buyer recommendations below.

Who should buy which

Pick the Prenuvo Whole-Body MRI if

Buyers with family history of cancer, anyone over 50, those who want imaging-based screening as part of their longevity baseline.

Skip if

You're prone to anxiety over uncertain findings, or you don't have $1K-2.5K to spend on a screening test.

Pick the TruDiagnostic TruAge COMPLETE Epigenetic Test if

Longevity-focused buyers running serious anti-aging protocols who want validated pace-of-aging tracking, and biomarker-literate users adding epigenetic data to a broader monitoring stack.

Skip if

You want actionable health recommendations (Function Health or InsideTracker beat it on that), you won't commit to longitudinal retests (single-point readings are noisy), or you're shopping for vanity rather than research-grade data.
