SmD1

The SmD1 test detects the presence of anti-Sm antibodies, often found in individuals with systemic lupus erythematosus (SLE), a type of autoimmune disease. The SmD1 test specifically helps doctors diagnose lupus, as these antibodies are highly specific to the disease. A positive result for anti-SmD1 antibodies, along with other clinical signs and symptoms, may help confirm the diagnosis of SLE. However, not everyone with lupus will have these antibodies, and they can sometimes be present in other conditions. On the other hand, a negative result means that these specific antibodies were not detected in the blood. While a negative result makes SLE less likely, it doesn't completely rule it out, as some individuals with lupus may not have detectable anti-Sm antibodies.
