Blood Group Guide / रक्त समूह जानकारी

ABO and Rh blood groups are important for transfusion compatibility. A simple compatibility chart can help with general education, but actual transfusion decisions require a blood bank.

Why cross-matching matters

Before transfusion, trained laboratory staff check blood type, screen donated blood and perform compatibility testing. A website chart cannot replace this process.

Blood requests

Health Sathi can accept a request containing the required blood group, hospital or blood bank, city and urgency. An administrator should verify the request before it appears publicly. Contact information should be published only with the requester’s consent.

Donation eligibility

Eligibility depends on age, health, local blood-bank rules and professional screening. People should follow the requirements of an authorized blood bank rather than relying on a website alone.
