Blood Transfusions

Evaluating Risk Factors: Blood Transfusions

Evaluating your likely current (and near future) state of health means taking into account the risk factors — such as blood transfusions — that affect you.   Our medical diagnosis tool, The Analyst™, identifies major risk factors by asking the right questions.

In the Past Medical Procedures section of the questionnaire, The Analyst™ will ask the following question about blood transfusions:
Have you received any blood transfusions?
Possible responses:

→ Yes, one
→ Yes, several

The Diagnostic Process

Based on your response to this question, which may indicate blood transfusions, The Analyst™ will use differential diagnosis to consider possibilities such as:

Babesiosis can, in extremely rare cases, be spread person-to person through blood transfusions.


While transfusion-related HIV and hepatitis are now relatively rare events, emerging or unknown infections, transfusion errors, and immunomodulation remain compelling reasons to minimize the use of allogeneic transfusion.


Each year in the United States, a few cases of malaria result from blood transfusions, are passed from mother to fetus during pregnancy, or are transmitted by locally infected mosquitoes.

West Nile Virus

West Nile virus can be spread through blood transfusions.
