What abnormal results mean
Abnormal results can be due to a variety of different medical conditions, including kidney failure, breathing problems, and diabetes-related complications. See the individual tests listed in the normal values section for detailed information.
What the risks are
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:
Fainting or feeling light-headed
Hematoma (blood accumulating under the skin)
Infection (a slight risk any time the skin is broken)
