Gout disease is suspected when a person reports an attack history of pain in different joint areas, especially at the bottom of the toes. Knees and ankles are the next most usually affected joints in this disease. Gout pain commonly attacks one joint every time whereas other types of arthritis, such as rheumatoid arthritis and SLE or systemic lupus erythematosus attack multiple joints at once. The most essential diagnostic examination is the joint aspiration. This test is the most reliable method of being assured of a gout diagnosis, in contrast with other origins, such as a joint infection. Joint aspiration is a test wherein uric crystals are searched for in a sample of the joint's fluid obtained in this test. This procedure is also known as arthrocentesis. Arhtrocentesis is a usual clinic procedure done under the influence of local anesthesia. Utilizing sterile techniques, the synovial fluid is aspirated or withdrawn from the inflamed area using a sterile needle and syringe. The needle is introduced into a joint to extract a sample of synovial fluid for evaluation. The synovial fluid is analyzed for the presence of uric crystals from the aspirated material from bursitis fluid and tophi nodules. The needle-like and shiny uric crystals are best observed using a highly polarized microscope. Even though many physicians can do the test, a rheumatologist is a specialist that is trained to perform this procedure. In some instances, other substances are found in the synovial fluid like calcium pyrophosphate. A pseudo-gout condition arises when this substance is found in the fluid. Sometimes, a person with a classic manifestation and history of gout may be effectively presumed and managed to have the disease without going through arthrocentesis. Nevertheless, establishing a reliable diagnosis is still preferred since other diseases may mimic gouty arthritis. These involve another diseases originated from crystal formations called psoriatic arthritis and rheumatoid arthritis. Gout is occasionally diagnosed according to its usual clinical manifestations even without aspiration. The physician can suggest a blood sample to evaluate the patient's acid levels, cell counts, kidney function, etc. Regrettably, the uric acid levels in the bloodstream can't be reliable enough to make a diagnosis of the disease. It is typical in approximately ten per cent of people who has gout experience acute attacks. The uric acid levels are commonly low during the peak of the inflammation stage. It would be best to determine the levels of uric acid after the flare subsided. X-rays are mainly used to determine underlying joint injuries, particularly in patients who have had several gout attack episodes.
