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/IGM 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 an active infection with the T cells, the Elispot is recommended.
Elispot For current active infections with:
Borrelia burgdorferi, Anaplasma, Ehrlichia, Chlamydia pneymoniae, Chlamydia trachomatis, Yersinia, Epstein-Barr Virus, Cytomegalovirus, Babesia, Bartonella, Mycoplasma and Varicella zoster virus .
- This test is highly sensitive and can detect even one single Borrelia burgdorferi-reactive T-cell. This is one of the most sensitive cellular assays available, as detection levels can be as low as one cell in 100,000. .
- The Elispot reflects chronic and recent Borrelia burgdorferi infections. .
- It is between 20 and 200 times more sensitive than a conventional ELISA test.
- The EliSpot displays similar sensitivity to an RTPCR (Real Time PCR) analysis, but detects the secreted protein instead of the mRNA (messenger RNA). .
This test can be helpful in monitoring therapeutic treatments. It should become negative about 4 to 8 weeks after the completion of an effective therapy.
The Epstein-Barr Virus Elispot-LTT test is designed to detect the Epstein–Barr virus (EBV), also called human herpesvirus 4 (HHV-4), which is of the herpes family, and is one of the most common viruses in humans.
The Epstein-Barr virus is best known as the cause of infectious mononucleosis (glandular fever). However, it s also associate with particular forms of cancer, such as Hodgkin’s lymphoma, Burkitt’s lymphoma, nasopharyngeal carcinoma, and central nervous system lymphomas, associated with HIV.
Elispot-LTT tests:
The result of the EliSpot test indicates current celluar activity against Epstein-Barr-Virus (EBV).
- EBV-lytic antigen: sign for replication of infectious EBV virions
- EBV-latent antigen: sign for EBV latency with no production of infectious EBV virions
