Glossary Flashcards
Bleeding disorder due to deficiency of a particular coagulation factor
Hemophilia
These are antibodies characterized as weak and can be diluted to high titer despite the weak reaction strengths.
High Titer Low Aviditity HTLA
Factor VIII deficiency mostly for males
Hemophilia A
AKA Christmas disease. Due to absence of FActor IX
Hemophilia B
Low RBC count resulting from destruction of circulating erythrocytes.
Hemolytic anemia
Condition in which a patient has shortened red blood cell survival associated with hemolysis mediated by humoral anti body.
Immune Hemolytic Anemia
Continuous red blood cell destruction resulting to anemia due to the presence of autoantibodies directed against the patients own red blood cells.
Autoimmune hemolytic anemia
It is the red blood cell destruction due to drug induced production of an autoantibody that recognizes red blood cell antigen
Drug induced hemolytic anemia
Red blood cell destruction due to the presence of alloantibodies to foreign red cell antigens introduced to the circulation through transfusion or pregnancy
Alloimmune hemolytic anemia
An increase in the volume of blood plasma resulting to reduced concentration of red blood cells
Hemodilution
it is a plasma protein which binds to hemoglobin following intravascular hemolysis
Haptoglobin
a very small substance to stimulate antibody production without attaching to a larger molecule
Hapten
These are genes that are close on the chromosome and inherited together by an individual
haplotype
condition characterized by markedly decreased leukocytes in the blood
Granulocytopenia
Intense and frequently fatal immunologic reaction of engrafted cell against the host caused by the infusion of immunocompentent lymphocytes into individuals with impaired immunity
Graft vs Host disease GVHD
Unit of inheritance within the chormosome
Gene
A pair of gene in which neither is dominant over the other, that is, they are bothh expressed.
codominant
A gene that does not appear to produce a detectable antigen
Amorphic
One of two or more different genes that may occupy a specific locus on a chromosome
Allelic
A gene that expressed if present
Dominant
A gene which is not expressed unless it is in the homozygous form
Recessive
A gene that produces a repressor substance that inhibits an operator gene
Regulatory
A gene that suppresses the phenotypic expression of another gene
Supressor
Specific place on the chromosome where a gene is located
Gene locus
