In short, you should see your physician for a comprehensive examination. ANA-negative SLE patients are known to have a higher prevalence of anti-Ro antibody and cutaneous manifestations, as well as a lower prevalence of both central nervous system and renal involvement [ 4 , 7 ]. A negative test. It does not rule-in or rule-out any disease. It is possible to have a negative ANA but a positive specific antibody test, though this is very uncommon; for diagnosis a positive test for a specific antibody is more important than is a negative ANA test. My thoughts are with those who are doing it tough. Cell-bound complement activation products in SLE. Lupus (and Sjogren's) can play a merry dance like this for a decade or more with both your ANA and ENA antibody panels before you finally turn up a positive result for it (lupus) in an ENA panel. Of these, 5216 patients had ANA tests ordered between January 1 and March 31 in any year, with 3071 having returned a negative ANA result and 803 of these having also had a dsDNA ordered (Table 1). The initial requirement of the criteria for lupus diagnosis is a positive ANA test with a titer of at least 80. An ANA test will be positive 95 percent of the time when a person has lupus, so there are cases where a person has lupus and will have negative ANA testing. ENA test for several different things. Testing is, therefore, not recommended when ANA is negative, where the probability of lupus would be expected to be low. These may be ANA negative though ENA positive. I am always tired and struggle to get out of bed but I'm also a student so that's pretty much a given. A negative result means it found none. THE SIGNIFICANCE OF ANTINUCLEAR ANTIBODIES Patients with the following systemic autoimmune diseases may have a positive test for antinuclear antibodies (ANA): dsDNA antibodies are very specific for lupus (as they are not typically seen in any other condition or in healthy population) only approximately 60% of people with SLE will test 'positive'. If a person has a positive ANA, an anti-dsDNA test may be used to distinguish lupus from other autoimmune disorders that have similar signs and symptoms. Other Diagnostic Tests. While many of these patients will never develop autoimmune disease, a positive ANA may appear several years before clinical symptoms in patients ultimately diagnosed with lupus. If all three test results are positive, then a lupus . Came back with positive ANA, negative ENA. If the ENA blood test is negative, but the ANA blood test is positive, then the combination of results may lead to additional testing or a diagnosis based on personal signs and symptoms. The sun only affects people w/ lupus that way. ANA-negative SLE patients are known to have a higher prevalence of anti-Ro antibody and cutaneous manifestations, as well as a lower prevalence of both central nervous system and renal involvement [ 4 , 7 ]. This disease is associated with various positive antibodies, some of which are specific to Lupus, some of which indicate another autoimmune disease, and Renal biopsy showed lupus nephritis class 1B. The ANA test was ordered along with a lot of other blood tests to rule out my symptoms (sore arm muscles). Autoantibodies on the ENA panel were generally not elevated in the high ANA HC group. 3).2,8,9 If the ANA IFA is positive, a positive result on one of the cascade tiers may suggest the presence of a certain autoimmune disease(s) ( Figure 1 , Table 3 ). SSA ad SSB are part of the ENA category which is a sub category of ANA. •A negative automated ANA requires a subsequent IIF ANA assay •A negative automated ANA requires a separate ENA assay •In some rheumatic diseases there are specific ANAs that may lead to tissue damage: •Anti-DNA antibodies in lupus nephritis •Anti-SSA antibodies in neonatal lupus Ann Rheum Dis 2010;69:1420 An ANA test confirms whether or not a person has an autoimmune disorder.

For myself, ANA tests negative. Don't get me wrong, these tests are important. I do get frequent joint . There are more than 100 antigens that have been identified as being extractable, but it is only these 6 that are routinely tested. An anti-ENA screen is usually prescribed following a positive result in an antinuclear antibody (ANA) test. 7. Whilst many patients with active untreated lupus produce anti-dsDNA antibodies, the sensitivity of this test is limited, with approximately just 60% of patients with lupus having a positive test result. This means that anyone that could have a possible auto-immune connective tissue disease such as Lupus will have a positive test, but it doesn't tell you if you certainly have one or which one you have. (other minor things like brain fog and fatigue) Back then, it was positive so I saw a rheumatologist who said I didn't test . As a physician I care about symptoms and signs way more than lab tests. In today's article, we are going to share all the information needed about the ANA blood test, ANA blood test normal range, and what does positive and negative ANA blood test mean. ANA and still have Lupus. People with lupus who have a negative ANA test may have anti-Ro/SSA or antiphospholipid antibodies. 30% of Lupus patients test positive for this antibody. I have an ANA titer of 5120 (since 2 years), and a positive AMA titer, but since my ENA is negative I'm still without official diagnosis after many, many years. Wow! In people with a positive ANA, more tests are usually performed to check for other antibodies that can help to confirm the diagnosis. It test for antibodies to Smith, SSA, SSB, RNP, Jo-1 and Scl-70. My doctor feels this is a low positive and I do not have an autoimmune disease. Serological investigations for HBV and HCV were negative, VDRL non-reactive, anti cardiolipin antibody was negative but lupus anticoagulant came positive.

Similarly, a speckled pattern on the ANA test can indicate almost ANY autoimmune disease, this is because a speckled pattern like a 1:80 titer level is not very significant. Although antibodies to extractable nuclear antigens (ENA) are sometimes ordered despite a negative ANA, it is unclear if this contributes to the diagnosis of SLE or other forms of connective tissue disease (CTD). I have always been confused by how it is possible to have a negative ANA but positive for SSB or SSA. Theoretically it is actually impossible. I don't know: An ANA of 1:320, speckled pattern, is a non-diagnostic test. ANA is measured in how strongly it is positive, usually measured as 0 to 4+ or as a titer (the number of times a blood sample can be diluted and still be positive).

The final diagnosis was ANA negative SLE (Ro lupus) with cutaneous, renal, musculoskeletal, hematological and cerebral Involvement. A negative ANA test effectively excludes a diagnosis of ANA associated rheumatic disease such as drug-induced lupus and, in the majority of cases . ENA positivity, namely anti-SSA, is rarely detectable in ANA negative patients, because anti-SSA antibodies recognise some cytoplasmatic antigens, and not only nuclear antigens. There were no significant associations between the different ANA patterns and AD diagnoses in positive and negative anti-ENA patients, suggesting no specific association of ANA . The age of onset and the female predominance are the same for ANA-negative SLE as for ANA-positive SLE . A negative test. It can be present in MCTD (mixed connective tissue disorder), Sjogren's syndrome, lupus, and many more autoimmune disease but the pattern is MOST commonly present in ….

Other Diagnostic Tests. People with lupus who have a negative ANA test may have anti-Ro/SSA or antiphospholipid antibodies. That also means that it is very rare to have lupus with a negative (normal) ANA. Although antibodies to extractable nuclear antigens (ENA) are sometimes ordered despite a negative ANA, it is unclear if this contributes to the diagnosis of SLE or other forms of connective tissue disease (CTD). Many people with no disease have positive ANA tests — particularly women older than 65. She then sent me to a hematologist who in turn did a lot of blood work, x-rays, and another ultrasound.

The simple explanation is that the ANA test is not reliable and when you have a positive ENA then the test result for ANA is wrong.. High ANA for years but negative lupus results. Objective. Systemic lupus erythematosus (SLE) rarely presents with a negative antinuclear antibody (ANA). The prevalence (70%) of anti-dsDNA autoantibody is much higher in SLE, giving a higher diagnostic sensitivity than the similarly disease-specific anti-Sm autoantibodies (30%). Usually done as a follow up to a positive antinuclear antibody (ANA) test and one is showing symptoms of an autoimmune disorder.

Nearly all people with systemic lupus erythematosus (SLE) have a positive (abnormal) ANA -- that is, the sensitivity of the ANA for SLE is quite high. Positive ANA test leads to further investigation of extractible nuclear antigens (ENA) . He thought lupus was unlikely given the ENA and I have no skin rash. Due to the prominent skin lesions, we performed anti-extractable nuclear antigens (ENA) antibodies test and anti-Ro turned out to be positive. But for the most part, I stay out of the sun as much as possible. A positive ANA may mean you have an autoimmune disease, which can include Lupus, Sjogren's, scleroderma, Rheumatoid arthritis or Raynaud's. Or it may even be a false positive.
