Polymorphisms of Vitamin D receptor (GVDR)
Bsm1 and Fok1 are two SNP's in the gene coding for VDR (vitamin D receptor).VDR is not only involved in skeletal metabolism but also in modulation of immune response, regulation of cell proliferation and differentiation. VDR dysfunction has been linked with osteoarthritis, cancer, diabetes and cardiovascular disease.

Elastase expression assay (ELAS)
Elastase is an inflammatory protease expressed in immune cells. Elastase contributes to the immune defense by inactivating foreign bacteria but causes damage to connective tissue and breaks down cytokines, immunoglobulins and immune cells receptors at the same time.

RNA-based tests : One TempusTM tube. Stable for 72 hours at ambient temperature. For longer periods freeze and ship at -20°C

Perforin expression assay (PERF)
Natural Killer cells (NK) are cytotoxic cells that mediate the immune response against certain cancer and virus-infected cells. NK cells are normally found in the peripheral blood and are classified by their cell surface markers such as CD3-/CD56+ cells.

Cytokine RNA, inflammatory

A principal avenue of investigation has been the measurement in blood of immune signals conducted by cytokines.
In animal studies, administration of pro-inflammatory cytokines (IL-1, TNF-α, and IL-6) directly into the brain can induce "sickness behaviors" that strongly resemble the symptoms of CFS. In particular, decreased motor activity, altered food and water intake, sleep and cognition have been linked to

Ammonia serum levels (AMMON)
Ammonia is derived from bacterial enzymatic action on ingested amino acids. It is absorbed from the gastrointestinal tract and delivered through the portal vein to the liver, which converts most of it into urea.
