Guttate Psoriasis Diagnosis
Guttate psoriasis is typically diagnosed after a doctor or health-care professional performs a physical exam of the skin. The dermatologist (skin doctor) generally can tell if it is psoriasis just by clinical judgment based on the presence of the skin lesions. Skin biopsies are seldom necessary to confirm diagnosis. Occasionally it may be necessary to perform other blood tests to rule out other treatable diseases.
Findings from blood tests may confirm that the patient had a streptococcal infection recently. Increased levels of antibodies to the streptolysin-O are present in more than one-half of patients.
