How is psoriasis diagnosed?

Diagnosis of psoriasis. Your doctor will ask about your symptoms and examine you. He or she will probably be able to diagnose psoriasis from your symptoms and by looking at your skin and nails. Your doctor may refer you to a dermatologist (a doctor who specialises in identifying and treating skin conditions) if a definite diagnosis can’t be made or if your psoriasis is:
• extensive or severe
• affecting your education or work
• not responding to treatment


If you have generalised pustular psoriasis or erythrodermic psoriasis, you may need to go to hospital for urgent treatment.
