Goodpasture syndrome Signs and symptoms [edit]. The anti glomerular basement membrane (GBM) antibodies primarily attack the kidneys and lungs, although, generalized symptoms like malaise, weight loss, fatigue, fever, and chills are also common, as are joint aches and pains.

DAT The antibodies present in the blood do not, themselves, cause agglutination. It is the addition of an antibody made in animals (antiglobulin) that stimulates red blood cell clumping. The direct antiglobulin test (DAT) is used to diagnose autoimmune hemolytic anemia and hemolytic disease of the newborn. The indirect antiglobulin test (IAT), or Coombs' test, is used to identify blood types.

Infectious Mononucleosis Heterophil antibody tests such as the Paul Bunnell or Monospot tests may be used in the diagnosis of glandular fever. Heterophil antibodies have the ability to agglutinate red blood cells of different animal species. The Paul-Bunnell test uses sheep erythrocytes; the Monospot test, horse red cells. In infectious mononucleosis, IgM heterophil antibodies are usually detectable for the first 3 months of infection.

- Goodpasture's disease (also known as Goodpasture Syndrome, anti-glomerular basement membrane disease, anti-GBM disease) is an uncommon condition which can cause rapid destruction of the kidneys and bleeding into the lungs.

Elevated antinuclear antibodies and altered anti-Epstein-Barr virus immune responses Anti-VCA IgM Abs were more frequently found in those patients with a very high titer of ANA (P = 0.06); moreover detection of anti-VCA IgM/IgG in absence of anti-EBNA-1 IgG was more frequent in the patient than in the control group. Both these conditions correlate with a recent EBV infection or reactivation.

Granulomatosis with Polyangiitis (GPA or Wegener's Granulomatosis) A more specific blood test used to diagnose and monitor Wegener's granulomatosis is the antineutrophil cytoplasmic antibody (ANCA test), which is commonly elevated when the disease is active. The diagnosis of GPA is confirmed by detecting both abnormal cellular formations, called granulomas, and vasculitis in a biopsy of tissue involved with the inflammatory process.

ASO The anti-DNase B and ASO tests do not predict if complications will occur following a streptococcal infection, nor do they predict the type or severity of the disease. If symptoms of rheumatic fever or glomerulonephritis are present, an elevated anti-DNase B and/or ASO titer may be used to help confirm the diagnosis.n anti-DNase B and another streptococcal antibody test, such as an antihyaluronidase test, may be ordered when an ASO test is negative to seek confirmation of a previous strep infection. Some symptoms of rheumatic fever may include:

HIV and Hormones Overproduction of thyroid hormones (hyperthyroidism) causes rapid metabolism, insomnia, anxiety, weight loss, and heat intolerance. Conversely, underproduction (hypothyroidism) is characterized by slow metabolism, fatigue, depression, weight gain, muscle and nerve dysfunction, and cold intolerance.

ANCA/MPO/PR3 Antibodies Vasculitis. An ANCA test and/or tests for MPO and PR3 are ordered when a person has signs and symptoms that suggest systemic autoimmune vasculitis. Early in the disease, symptoms may be vague or nonspecific, such as fever, fatigue, weight loss, muscle and/or joint aches, and night sweats. Most often, ANCA tests are performed using indirect immunofluorescence microscopy (IFA). 2  Serum samples are mixed with neutrophils to allow autoantibodies that may be present to react with the cells. 3  The sample is put on a slide and treated with a fluorescent stain.

- According to the revised Japanese criteria for the diagnosis of MPA put forward by the National Study Group of Angiitis , the diagnosis of ' definite MPA ' is made in the existence of one of the two following conditions : MPO-ANCA is detected in patients presenting with both rapidly progressive glomerulonephritis ( RPGN ) and pulmonary hemorrhage or ...

Pauci-immune Since it can be associated with the three systemic vasculitides mentioned above, a pauci-immune pattern finding can be associated with antineutrophil cytoplasmic antibodies (ANCA). Therefore, an ANCA test should follow a negative immunofluorescence result in order to distinguish between the above-mentioned systemic vasculitis.

Approach Considerations The laboratory hallmark of giant cell arteritis (GCA) is an elevation in the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level.The ESR usually exceeds 50 mm/h and may exceed 100 mm/h, but may be normal in 7-20% of patients with GCA.lthough superficial temporal artery biopsy remains the standard for diagnosis of giant cell arteritis (GCA), color duplex ultrasonography can be used to diagnose GCA.
