Getting Diagnosed with Ichthyosis

Understand the diagnostic journey, available tests, and the role of specialists in identifying and confirming ichthyosis.

The Diagnostic Journey

Visit your GP with concerns about dry, scaly skin. Describe symptoms, triggers, and family history.

Dermatologist examines skin appearance, distribution, and severity. Initial diagnosis often made clinically.

Additional tests may include biopsy, genetic testing, or other investigations to confirm type.

Test results confirm ichthyosis and identify the specific type affecting you.

Develop personalized management plan with your medical team.

Visual examination of skin characteristics including scale appearance, distribution, and severity. Often sufficient for diagnosis.

Small sample of affected skin examined under microscope. Shows specific histological patterns characteristic of ichthyosis type.

DNA analysis identifies mutations in genes responsible for ichthyosis. Confirms type and inheritance pattern.

Measures lipid composition of skin. Abnormalities indicate barrier dysfunction and may confirm specific types.

Specific test for filaggrin mutations. Important for ichthyosis vulgaris diagnosis and prognosis.

Measures water loss through skin barrier. Elevated in ichthyosis, confirms barrier dysfunction.

Primary specialist for skin diagnosis and management. Coordinates care, prescribes treatments, and monitors progress.

Explains inheritance patterns, genetic testing options, and implications for family planning and relatives.

First point of contact. Refers to specialists, monitors ongoing care, and prescribes routine treatments.
