Did You Know?

Psoriatic arthritis (PsA) is a common comorbidity of psoriasis. PsA can lead to permanent damage to bones and joints, especially if untreated. Currently, no diagnostic test for PsA exists. Thankfully, validated screening tools exist to help identify signs and symptoms of the disease..

The Psoriasis Epidemiology Screening Tool (PEST) is a validated screening tool for psoriatic arthritis [2]. It is recommended that individuals with psoriasis complete the PEST screener every six months. Forty-one percent of those who screened positive for PsA using the PEST had not previously been diagnosed with PsA.
