Interpretation of ferritin concentrations in the dermatology clinic

Ferritin measurement is a common laboratory test in dermatology. Ferritin is a marker of iron storage in the human body but can also be -elevated in inflammatory states. Therefore, changes in ferritin are nonspecific, and correlation of specific clinical findings and risk factors with ferritin concentration and other biomarkers, e.g. iron studies or C-reactive protein tests, is recommended. This article discusses iron metabolism and the indications for ferritin measurement in dermatology and how to interpret the laboratory results.
