Licensed blood banks in India screen donated blood for
HIV, hepatitis B/C, syphilis and malaria. NAT is an additional sensitive test and is not guaranteed at every branch; it depends on the blood centre's policy.
For your mother's transfusion, ask the hospital blood bank whether ID-NAT was performed and request the screening report or unit details. If there is a specific exposure concern, her nephrologist can guide follow-up testing.
Next Steps
Contact the hospital blood bank and ask for the written screening report, including whether ID-NAT was used. You can book a Practo consultation if you want help interpreting the report.
