Pregnancy & blood.

Blood groups in pregnancy, ABO, testing and transfusions

Why every pregnancy starts with a blood group test, what ABO incompatibility means (and why it's milder than Rh), and when transfusion happens during pregnancy.

Can blood transfusions transmit disease? The testing, honestly

Every unit in India is tested for HIV, hepatitis B and C, syphilis and malaria. How testing works, what the real residual risk is, and why voluntary donors are the safest donors.

Massive transfusion and trauma, when a body needs blood at scale

What massive transfusion protocols are, how blood loss staggers the body, why O− units and balanced component packs exist, and where registers fit into disaster readiness.

Rh incompatibility in pregnancy, anti-D and why it matters

When an Rh− mother carries an Rh+ baby: sensitisation, haemolytic disease of the fetus and newborn, and how anti-D injections prevent it. Plain language.

Transfusion reactions, what can happen, and how staff watch for it

The kinds of transfusion reactions (fever, allergic, haemolytic, delayed) why most are mild and manageable, and how the system catches the rare serious ones early.
