T3
Alternate Names : Triiodothyronine, T3 radioimmunoassay
Risks
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. Other risks associated with having blood drawn are slight but may include: - Excessive bleeding
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
Special Considerations
Pregnancy and liver disease will falsely raise the T3 level. In these cases, it is useful to measure either the free T3 level or to perform the T3RU test.
