A viral titer is the lowest concentration of a virus that still infects cells. To determine the titer, several dilutions are prepared, such as 10 −1, 10 −2, 10 −3, ... 10 −8. [1] The titer of a fat is the temperature, in degrees Celsius, at which it solidifies. [4] The higher the titer, the harder the fat.
Serology is the scientific study of serum and other body fluids.In practice, the term usually refers to the diagnostic identification of antibodies in the serum. [1] Such antibodies are typically formed in response to an infection (against a given microorganism), [2] against other foreign proteins (in response, for example, to a mismatched blood transfusion), or to one's own proteins (in ...
Antibodies to tissue transglutaminase (abbreviated as anti-tTG or anti-TG2) are found in patients with several conditions, including celiac disease, juvenile diabetes, [1] inflammatory bowel disease, [2] and various forms of arthritis.
Heterophile also can mean that it is an antibody that reacts with antigens other than the antigen that stimulated it (an antibody that crossreacts). [citation needed] A 20% suspension of horse red cells is used in an isotonic 3–8% sodium citrate formulation. One drop of the patient's serum to be tested is mixed on an opal glass slide with one ...
ANAs are found in many disorders, as well as some healthy individuals. These disorders include: systemic lupus erythematosus (SLE), rheumatoid arthritis, Sjögren syndrome, scleroderma, polymyositis, dermatomyositis, primary biliary cirrhosis, drug induced lupus, autoimmune hepatitis, multiple sclerosis, discoid lupus, thyroid disease, antiphospholipid syndrome, juvenile idiopathic arthritis ...
This updated version was released in 2015 as SISO-STD-001. RPR FOM 2.0 supports the capabilities of DIS version IEEE 1278.1a-1998 (DIS 6). The development of RPR FOM 2.0 started in 2000, but came to a halt in 2007, resulting in a widely used draft version 17. The work was restarted in 2012 and finalized with a published standard in 2015.
Nodules are associated with a positive RF (rheumatoid factor) titer, ACPA, and severe erosive arthritis. Rarely, these can occur in internal organs or at diverse sites on the body. [22] Several forms of vasculitis occur in RA, but are mostly seen with long-standing and untreated disease. The most common presentation is due to involvement of ...
