What is the most common immunodeficiency?
|
selective IgA deficiency
|
|
|
______________ measures the light that is scattered at a particular angle from the incident beam as it passes through a suspension. The amount of light scattered is an index of the suspension’s concentration. The light scatter changes proportionally with antigen-antibody complex formation.
|
nephelometry
|
|
|
Which serology test has the benefit of allowing multiple tests on a small sample by using color-coded polystyrene microspheres
|
Fluorescent Microsphere-based Immunoassay
|
|
|
What lab test is commonly used as a confirmatory test for HIV?
|
Western Blot
|
|
|
What are the 4 clinical settings for immune-mediated hemolysis?
|
Transfusion reaction, Hemolytic disease of newborn, drug-induced hemolysis, autoimmune hemolytic anemia
|
|
|
What serum antibody/rbc antigen would present in a blood type A patient? type B? type AB? type O?
|
Type A: Anti-B Ab(antibody), A Ag(antigen); Type B: Anti-A Ab, B Ag; Type AB: no Ab, A and B Ag; Type O: Anti-A and Anti-B Ab, H antigen
|
|
|
What blood type is the 'universal donor'? What blood type is the 'universal recipient'?
|
Universal donor: Type O (there are no anti-bodies acting against H antigen); Universal recipient: Type AB (because it produces neither Anti-A nor Anti-B Ab's, the patient can receive blood of all types)
|
|
|
Which antigen contributes to hemolytic disease of newborn?
|
D (Rhesus blood group)
|
|
|
are most of the population Rh+ or -?
|
Rh+
|
|
|
Would the first Rh- baby of a Rh+ mother have hemolytic disease? Why or why not?
|
No. This would not occur until subsequent pregnancies because the mother had not yet developed memory cells in the first pregnancy. During the second and subsequent pregnancies, IgG against D antigen would reach the fetal circulation.
|
|
|
What is used to prevent hemolytic disease of newborn?
|
Anti-Rh prophylaxis administered to Rh- mothers
|
