3
what does IFN-g do
it activates macrophages and causes the differention of helper t cells
4
IFN-g is produced by
activated t lymphocytes and NK cells
5
IFN-g release assy test for what
latent TB
6
IFN-g test what kind of immune response
cell mediated
7
what does elevated lactate DH mean
that there is cell damage or tissue damage, it is also high when bacteria is present
also seen when there is hemolytic anemia
8
due to the immune response seen when someone has mycoplasma what can happen
the patient can have hemolytic anemia because the antigens on the bacteria are the same as the ones on the red blood cells ( production of cold agglutinins IgM)
