How to diagnose psoriasis?

A individual with joint aches and pains should speak with a doctor about diagnosis and treatment.

There’s no definitive test for psoriatic arthritis. The diagnosis is made largely on a clinical basis and by a process of elimination. Medical history, physical examination, blood tests, MRIs and X-rays of those joints which have symptoms could possibly be used to diagnose psoriatic arthritis. It’s important to convey your history of psoriasis to your physician.

Rheumatoid arthritis generally involves joints symmetrically distributed on either side of the body, and it might create lumps under the skin that aren’t present in psoriatic arthritis. But some types of psoriatic arthritis seem very similar.

A particular antibody, known as a rheumatoid factor, is normally present in rheumatoid arthritis. The rheumatoid factor isn’t ordinarily found in the blood of psoriatic arthritis patients. A blood test for this antibody can help differentiate between the two diseases. Someone may have rheumatoid arthritis and psoriatic arthritis, but that’s rare.

Likewise, it’s possible to have gout together with psoriasis and psoriatic arthritis. In case you have an excruciatingly painful attack in a joint, especially in the big toe, you might want a test for gout. Fluid drawn from the affected joint is analyzed to resolve the diagnosis of gout or psoriatic arthritis. Psoriatic arthritis patients are generally misdiagnosed as with gout, since they frequently have elevated serum uric acid levels, which also can be brought on by taking low-dose aspirin or by increased cell turnover. It’s necessary to differentiate between the two kinds of arthritis, since they might be treated with various medications.

At the very early stages of this disease, X-rays normally do not show signs of arthritis and may not assist in making a diagnosis. In the later phases, X-rays may reveal changes that are characteristic of psoriatic arthritis but not found with other forms of arthritis, like the”pen in cup” occurrence where the end of the bone gets whittled down to a sharp point. Changes in the peripheral joints and at the backbone support the diagnosis of psoriatic arthritis. However, the majority of the changes happen in the later stages of this disease.
