Quantitative immunoglobulins

There is very little risk involved with having your blood taken. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.

Other risks associated with having blood drawn are slight but may include:

• Excessive bleeding
• Fainting or feeling lightheaded
• Hematoma (blood accumulating under the skin)
• Infection (a slight risk any time the skin is broken)

Nephelometry determines the total amount of each immunoglobulin but cannot distinguish specific antibodies. Other tests such as immunoelectrophoresis or immunofixation can be used to make these distinctions.
