This test requires a blood draw, so please ensure you can refer to a phlebotomist in the clients area before you order this test.
Elispot looks at the T cell response and IGG looks at B cells/Antibodies.
Some people don't produce antibodies and have a more active T cell response.
In an ideal world to assess an infection, a practitioner should look at both sides of the immune system response, in other words, Eli-spot for the T cells/cellular response and IGG/IGM for humoral/B cell/antibody response.
To check for past exposure antibodies (IGG) please run this test, but for the best overview of the immune system, combine it with the relevant Elispot test.
