can we transfuse blood if the auto control is positive.?

Answer 1

it depends on what is causing the auto control to be positive, but it is generally recommended that blood not be transfused unless it is absolutely necessary. in the case of a cold antibody causing the auto control to be positive, the blood can be prewarmed to lesson the chance of problems. cold antibodies can cause an auto control to be positive but since they generally react at temps lower than body themp then it shouldn't cause a problem. many colds are caused by anti-I in which we could not find any antigen-negative blood. in many cases, if the auto is positive, the blood will likely be destroyed by autoantibodies and the transfusion will be of no help.

Answer 2

What auto control are you talking about?

You can transfuse the blood if:

- you have the right patient
- you have the right transfusion package (ie the blood to be transfused is correctly crossmatched with the patient)
- you have the patient's consent (or equivalent)
- you have the right facilities and staff

and you can transfuse O negative blood in emergency settings without the need for full matching
