Ever been deterred from donating blood? Dr Kunal Sood explains why donors may get rejected

Dr Kunal Sood explains common reasons for blood donation rejection: low haemoglobin, being underweight, and deep-seated veins.

Blood donation centres screen donors to protect both donor and recipient, per Dr Sood.

Low haemoglobin worsens anaemia, making donation unsafe.

Minimum weight requirement reduces risk of dizziness and fainting.

Many deferrals are temporary due to factors like recent tattoos, medications, infections, or travel to specific areas.
