6 Multiple choice questions

  1. Detects the presence of circulating immune complexes in type II hypersensitivity response
    Useful in autoimmune DO
  2. Cytotoxic
    Immune system identifies a normal part of the body as foriegn
    Causes- hemolytic transfusion reactions, IgG or IgM to cell-bound antigen
    Types- Goodpastures, Pernicious anemia, myasthenia gravis, thrombocytopenia
  3. Done if + indirect coombs or transfusion reaction occured
  4. Allergic Asthma
    Allergic rhinitis
    Hives
    Anaphylatic shock
  5. Vasodilation
    Increased cap permeability
    Smooth muscle contraction
    Bronchial constriction
  6. Rh & Type
    Prior to transfusions

6 True/False questions

  1. Classification of Hypersensitivity ReactionsHypersensitvity-Altered immune response to an antigen that causes harm to a person
    Allergy- Antigen is enviornmental or exogenous
    Allergen- what causes hypersensitivity reaction

          

  2. CBCDetects high level of circulating eosinophils

          

  3. Type IIIImmune complex (IgM & IgG)
    Circulating immune complexes deposited in body tissue
    Local inflammation & cell wall damage
    *persistent infections- edocarditism acute glomerulonephritis
    *Auto antibodies- rhematoid arthritis, systemic lupis

          

  4. Type IVCytotoxic
    Immune system identifies a normal part of the body as foriegn
    Causes- hemolytic transfusion reactions, IgG or IgM to cell-bound antigen
    Types- Goodpastures, Pernicious anemia, myasthenia gravis, thrombocytopenia

          

  5. Radioallergosorben Test (RAST)Detects presense of circulation antibodies against RBC
    Normal to not have agglunation
    Part of cross & match
    (Blood & trasnfusion blood mixed-reaction??)

          

  6. Skin TestDetects hypersensitivity reactions
    *Puncture, intradermal, scratch, food allergy
    *Increased risk for anaphylactic response
