A serology test can determine if a patient has ever been exposed to a particular antigen, but this does not necessarily indicate a current infection. A person who tests positive for B. anthracis may not develop anthrax.
If repeated tests show markedly increased response, current infection is more likely. In this case, actual symptoms will most likely dictate the best course of therapy before any changes in laboratory test values.
Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
