Psoriasis Diagnosis Tests: How to Determine if You Have the Condition

Psoriasis Diagnosis Tests: How to Determine if You Have the Condition

By definition, psoriasis is a condition that causes red, flaky, and crusty patches of skin that is covered with silvery scales. These tend to present on your elbows, knees, scalp, and lower back. However, they may appear anywhere on your body. Psoriasis is a lifelong condition, but there may be periods when symptoms are mild or not present. On the other hand, there may also be periods of severe symptoms. Learn more about the condition and the types of psoriasis diagnosis tests used.

Symptoms of Psoriasis: More Than Just Dry, Scaly Skin

How Prevalent is Psoriasis?

Psoriasis has been more commonly seen in northern European populations and least seen in eastern Asian populations. Psoriasis can affect people of any age. But it most often develops prior to the age of 35 years old, affecting both men and women almost equally.

Signs and Symptoms of Psoriasis

You can suspect that you have psoriasis if you notice dry, thick, and raised patches of skin that are covered by a silvery-white coat of scales that tend to be itchy or slightly painful. These symptoms may vary depending on the type of psoriasis you have as well as which body parts are affected and how severe the symptoms are. Identifying the symptoms and type of psoriasis will help your doctor determine the psoriasis diagnosis test you may need.

Psoriasis Diagnosis Tests

To date, there is no psoriasis diagnostic test that can determine the type of psoriasis without being invasive. The type of psoriasis you have is typically confirmed by the doctor during your physical exam.

The symptoms and the pattern and quality of the lesions will help your physician determine the type of psoriasis. If this is not enough, your doctor may request a biopsy, where a skin sample from your lesion will be analyzed under a microscope.

Key Takeaways

Psoriasis is a serious lifelong condition that affects a small percentage of the general population. The symptoms and types of lesions that people present with will determine the type of psoriasis that they have, which clinicians can use for their diagnosis. For proper diagnosis and treatment, consult your doctor.
