Altheome

About us

Altheome is a London-based specialist biomarker laboratory, providing clinical gold-standard NAD testing – measuring NAD+, NADH and the NAD+/NADH ratio from a small blood sample – so clinics can baseline patients, track response to NAD therapies and personalise dosing with data. Our test is the only CE-marked NAD test worldwide. Results come as a clear, actionable, patient-ready report.
