Serology for brucellosis

The risks associated with having blood drawn are:

• Excessive bleeding
• Fainting or feeling light-headed
• Hematoma (blood accumulating under the skin)
• Infection (a slight risk any time the skin is broken)
• Multiple punctures to locate veins

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. Increasing antibody levels are more likely to indicate a current infection.

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.
