Rhesus (Rh) factor
The Rhesus (Rh) factor is a protein found on the surface of red blood cells that determines whether a person’s blood type is Rh-positive or Rh-negative. Important for transfusion safety and pregnancy management.
The Rh factor is an inherited antigen, most commonly the D antigen, located on the surface of red blood cells. Individuals who have this protein are classified as Rh-positive, while those who lack it are Rh-negative.
The Rh factor is determined through a blood test and is commonly assessed alongside the ABO blood group system. It plays a crucial role in blood transfusions and pregnancy management, as incompatibility between Rh-negative and Rh-positive blood can trigger immune reactions.

A cycle built for lifelong progress
Each pass deepens the picture, tracks your trajectory, and makes the next recommendation smarter than the last.
If you are in Netherlands, please check the extra step regarding a kit you will receive before going to the lab.
Choose from +300 certified partner labs across Europe. Our first comprehensive draw captures +100 essential biomarkers, everything from cardiovascular markers and metabolic panels to hormone profiles and immune function. You show up. We handle the rest.
Our experts - not just algorithms - perform a whole-body analysis across cardiovascular, hormonal, metabolic, and immune systems. You receive an Axo Health Score, a Biological Age calculation, and a full breakdown of every marker: what it means, why it matters, and where you stand relative to true optimal ranges - not just lab reference ranges.
Your personalised health blueprint, built by Dr. Niko Mihic and Dr. Andy Walshe's sports science methodology. Not generic advice - specific, ranked, actionable interventions in nutrition, sleep, supplementation, exercise, and stress. Each recommendation is tied directly to your markers and calibrated to your lifestyle.
At the 6-month mark, a follow-up panel of targeted biomarkers confirms whether your interventions are working. Watch your score improve. See your biological age trend downward. Then the cycle begins again - deeper, sharper, and compounding with every pass.
