Tejas Ahire: Rh Incompatibility – A Small Blood Group Difference with Big Clinical Impact
Tejas Ahire, Junior Officer in Downstream Process at Hetero Biopharma, shared a post on LinkedIn:
“Rh Incompatibility: A Small Blood Group Difference with Big Clinical Impact
Rh incompatibility occurs when an Rh-negative mother carries an Rh-positive fetus.
During pregnancy, the mother’s immune system may develop antibodies against fetal red blood cells, which can affect future Rh-positive pregnancies.
Key points:
- First pregnancy is usually unaffected
- IgG antibodies can cross the placenta
- May cause fetal anemia, jaundice, and severe complications
- Anti-D immunoglobulin is highly effective in prevention
Understanding this mechanism highlights the importance of antenatal screening and timely preventive care.
As healthcare professionals and students, knowing the science behind Rh incompatibility helps us appreciate how early intervention can save lives.
Did you know that a simple Anti-D injection can prevent most cases of Rh incompatibility?”
