Why This Biomarker Matters

Rh status is critical for safe blood transfusions and pregnancy management. Rh-negative mothers carrying Rh-positive babies require preventive treatment to avoid complications.

Overview

Rh (Rhesus) type is an inherited protein found on the surface of red blood cells. Your blood type includes both ABO type (A, B, AB, or O) and Rh status (positive or negative). Rh-positive means you have the Rh protein; Rh-negative means you lack it. During pregnancy, an Rh-negative mother carrying an Rh-positive baby may develop antibodies that attack fetal red blood cells in future pregnancies, causing hemolytic disease. Testing is essential for safe transfusions and pregnancy management.
