WebEvaluating patients with signs and symptoms of scleroderma and other connective tissue diseases in whom the test for antinuclear antibodies is positive Testing for Scl 70 antibodies are not useful in patients without demonstrable antinuclear antibodies. Performance characteristics were verified by Mayo Clinic in a manner consistent with CLIA requirements. These are also referred to as extractable nuclear antigens. But that does not point to an autoimmune disease is present. MCTD is characterized by high levels of RNP antibodies without detectable Sm (Smith) or double-stranded DNA (dsDNA) antibodies. All rights reserved. Sjogren syndrome (SS)A (Ro), SSB (La), ribonucleoprotein (RNP), and Smith (Sm) proteins are autoantigens commonly referred to as extractable nuclear antigens (ENA). A primary laser reveals the fluorescent signature of each microsphere to distinguish it from microspheres that are labeled with other antigens, and a secondary laser reveals the level of PE fluorescence associated with each microsphere. It involves taking a blood sample from a vein in your arm using a sterile needle. Low to moderate levels of the autoantibody may be seen with other autoimmune disorders, such as Sjgrens syndrome and mixed connective tissue disease (MCTD).
