[10] On the other hand, they say, although 95% of the patients who actually have lupus test positive for ANA, "Only a small percentage have a negative ANA, and many of those have other antibodies (such as anti-phospholipid antibodies, anti-Ro, anti-SSA) or their ANA converted from positive to negative from steroids, cytotoxic medications, or ...
HEp-2 cells provide a greater ability to differentiate patterns of ANA than animal sections, due to the large nuclei and high mitotic rate of the cell line. Upon incubation with serum containing anti-dsDNA antibodies and fluorescent labelled secondary antibodies, homogeneous staining of interphase nuclei and condensed chromosomal staining of ...
Antinuclear antibody (ANA) testing and anti-extractable nuclear antigen form the mainstay of serologic testing for SLE. ANA testing for lupus is highly sensitive, with the vast majority of individuals with Lupus testing positive; but the test is not specific, as a positive result may or may not be indicative of Lupus.

A value of greater than 1.5 units relative to a control serum is considered a positive ELISA test for the anti-histone antibodies. Patients with drug-induced lupus erythematosus typically have positive tests for anti-histone antibodies but do not have indications for anti-dsDNA antibodies. Patients with idiopathic systemic lupus erythematosus ...
dry eyes, dry mouth, hair loss, joint inflammation, joint pain, mouth ulcers, positive ANA test, raynaud's phenomenon, sun-sensitive rash... Undifferentiated connective tissue disease ( UCTD ) (also known as latent lupus or incomplete lupus [ 1 ] ) is a disease in which the connective tissues are targeted by the immune system.
Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
ANA is a marker of the autoimmune process – it is positive with a variety of different autoimmune diseases but not specific. Consequently, if an ANA test is positive, it is often followed up with other tests associated with arthritis and inflammation , such as a rheumatoid factor (RF), an erythrocyte sedimentation rate (ESR), a c-reactive ...
In a suspected antiphospholipid syndrome, lupus anticoagulant is generally tested in conjunction with anti-apolipoprotein antibodies and anti-cardiolipin antibodies, and diagnostic criteria require one clinical event (i.e. thrombosis or pregnancy complication) and two positive blood test results spaced at least three months apart that detect at ...
