Blood test

Uroporphyrin levels; Protoporphyrin levels; Porphyrins - total; Coproporphyrin levels

Risks associated with having blood drawn are slight:

• 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

Failure to comply with dietary restrictions prior to the test may alter and invalidate test results.

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.
