Identification of Raynaud’s Syndrome
Once you reach out to your doctor regarding your condition, he/she will order a few Raynaud’s tests to conclude the disease. Generally, it is pretty easy to diagnose Raynaud’s but difficult to conclude its type. The Raynaud’s Phenomenon diagnostic tests include the following-
1. Nailfold Capillaroscopy: To determine whether the Raynaud’s is primary or secondary, doctors often rely on this test. In this test, a drop of oil is placed on the nail fold i.e., the area where the nail joins the skin. It is then examined under a microscope or a hand held ophthalmoscope to determine any kind of abnormalities in the capillaries. If the patient has Primary Raynaud’s the result of this test will be normal. However, if the capillaries appear enlarged or abnormal, then it may be deduced as a connective tissue disorder, meaning that the patient is diagnosed with Secondary form of Raynaud’s.When the conclusion is indicative of Secondary Raynaud’s, further tests are prescribed. They generally include a complete blood count, chemistry profile and a urinalysis.
2. Cold Simulation Test: Cold immersion test for Raynaud’s mimics the circumstances in which a Raynaud’s attack might occur. This Raynaud’s syndrome test is so designed that it triggers the symptoms of Raynaud’s. This test in isolation is not enough to prove Raynaud’s. It is conducted in conjunction with other tests.
3. Antinuclear Antibodies Test: This is one of Raynaud’s blood test commonly prescribed by the doctor. If you test positive for these antibodies, it reflects a stimulated immune system. This is often found in patients having an underlying history of autoimmune diseases and connective tissue disorders.4. Erythrocyte Sedimentation Rate: To confirm secondary Raynaud’s, this is another blood test used. It measures the settling rate of Red Blood Cells (RBC’s) at the floor of the test tube. A rate that is faster than the normal indicates an inflammatory condition or an autoimmune disease, thereby predisposing you to develop Raynaud’s symptoms.
Generally, these tests are enough to conclude the presence or absence of Raynaud’s Phenomenon. However, if the doctor wishes, they may prescribe other tests as well. But one shouldn’t be panicked by any of them. For it is only after your diagnosis is confirmed that one may begin the restorative therapy!
