How is psoriasis diagnosed?
- Physical examination: The doctor examines the skin thoroughly and observes the shape, color, and texture of the spots.
- History: The doctor asks about the patient’s medical history, and factors that may contribute to the onset of the disease, such as a family history of psoriasis, and exposure to environmental influences.
- Biopsy: In some cases, the doctor may take a small sample of skin to analyze under a microscope and confirm the diagnosis.
- Other tests: Your doctor may need to perform other tests to rule out other skin conditions, such as a blood test or fungal culture.
The importance of accurate diagnosis
- Appropriate treatment: Choosing the right treatment depends on the type of disease, so an accurate diagnosis is the first step to effective treatment.

Diagnosing psoriasis requires experience and skill by a doctor, as it must be differentiated from many other skin diseases that may resemble it in appearance. Through physical examination, disease history, and laboratory tests, the doctor can reach an accurate diagnosis and develop an appropriate treatment plan.
