alloantibodies การใช้

• During the final month of gestation, alloantibodies concentrate into the colostrum.
• Anti-K typically presents as IgG class alloantibody.
• For the remaining 12, alloantibodies against the thetical but not the antithetical antigen have been observed.
• Crossmatching using saline agglutination does run the risk of false negatives, since some alloantibodies only produce lysis rather than agglutination.
• Some mares have natural alloantibodies, usually to the Ca blood group, without ever having a known exposure to that blood group.
• Prognosis depends on the amount of alloantibody received and their potency, which may be indirectly measured by the degree of clinical signs.
• Mares with multiple exposures to a blood group antigen also produce a greater amount of alloantibodies and therefore the foal receives a larger dose.
• The severity of clinical signs and their speed of onset is determined by the dose of alloantibodies taken in by the foal and their potency.
• Alloantibodies against the Aa blood group are especially potent, and usually produce more severe signs than other alloantibodies when an equivalent dose is absorbed.
• Alloantibodies against the Aa blood group are especially potent, and usually produce more severe signs than other alloantibodies when an equivalent dose is absorbed.
• "' Isoantibodies "'( formerly called alloantibody ) are antibodies produced by an individual against isoantigens produced by members of the same species.
• An antibody panel consists of commercially prepared group O red cell suspensions from donors that have been phenotyped for antigens that correspond to commonly encountered and clinically significant alloantibodies.
• In addition, these alloantibodies will be present in a female dog's milk ( colostrum ) and adversely affect the health of DEA 1.1 negative puppies.
• A definitive diagnosis can only be made if alloantibodies are discovered in the mare's serum or colostrum and are shown to be against the foal's red blood cells.
• After a first affected pregnancy, if a mother has plans for a subsequent pregnancy, then the mother and father should be typed for platelet antigens and the mother screened for alloantibodies.
• Auto anti-LW is not uncommon as an autoantibody but usually presents with transient suppression of the LW antigen in genetically LW + individuals, and so appears to be an alloantibody.
• Development of alloantibodies occurs in 10-15 % of patients receiving human-derived medium-purity factor VIII concentrates and the risk of allergic reactions including anaphylaxis must be considered when administering these preparations.
• However, she must meet general criteria for donation and platelets received from the mother must be washed to remove the offending alloantibody and irradiated to reduce the risk of graft-versus-host disease.
• These natural alloantibodies have not been shown to produce isoerythrolysis in foals, and are actually thought to help prevent NI by desensitization of the immune system and preventing the more harmful Aa alloantibodies from forming.
