Overview
laboratory findings are usually normal for patients with restless leg syndrome.
Laboratory Findings
- As restless leg syndrome may be secondary to iron deficiency or kidney diseases, all patients should be screened for iron deficiency and kidney diseases.
- Iron studies usually done for detecting iron deficiency anemia are:[1]
- Serum iron- Decreased in iron deficiency
- Transferrin- Elevated in iron deficiency
- Total iron binding capacity (TIBC)- Elevated in iron deficiency
- Transferrin saturation- derived by dividing the serum iron by the TIBC. Decreased in iron deficiency
- Ferritin- Indicator of body iron stores and is low in iron deficiency. However, ferritin also acts as an acute phase reactant and can be unreliable in inflammatory illness
