Primarily, X-ray is the main equipment used to detect whether or not there are deformities or abnormal conditions happening in the joints. Although, most commonly it is the symptoms of arthritis which can easily be detected professional can be able to attain to the conclusion whether the patient has psoriatic arthritis depending on the same findings.
Secondly, fluid test has also been proven to give accurate information about the presence of psoriatic arthritis in a person. A specimen or sample will be taken from the knee which is then analyzed and diagnosed the presence of psoriasis in the pre-existing arthritic condition. However, if the presence of uric acid crystals is detected, it means that a person is suffering from gout but not psoriatic arthritis.
Furthermore, blood test is also used the sedimentation rate of erythrocyte in the blood. The process includes a close monitoring the falling time of hemoglobin or the red blood cells within a glass tube at a certain amount of time. If the red blood cells fall faster, there is a high sedimentation rate, thus, causing inflammation within the body especially the joints.
It may sound accurate at first but it is not because sedimentation rate in blood will also increase when arthritis, rheumatic or not, is present. Although, rheumatoid arthritis can be diagnosed when there is a certain protein being produced, still the sedimentation rate where blood test for this disease is based does not give accurate information. |
