The accumulation of EDN in the intestine is associated with inflammation and tissue damage. Measuring of EDN in stool can serve as an objective parameter for a current clinical or sub-clinical chronic inflammation located in the gastrointestinal area.

The intestinal microflora can be considered as a postnatally acquired organ. Composed of a large diversity of bacterial cells, it has different functions for the host.The microflora has a significant role in gut maturation, gut integrity, prevention of pathogenic and opportunistic bacterial colonization,… It modulates the immune system as well. The mocroflora is also involved in vitamin synthesis, production of short chain fatty acids, metabolism of carcinogenic substances.

Test Sampling Instructions

HHV-6 has a very high prevalence (close to 100% of the world’s population has been exposed). It is transmitted mainly by saliva. Transmission occurs usually within the first two years of life; primary infection is often associated with a febrile condition and sometimes with the onset of roseola (exanthem subitum).

Sample required: Blood: 2 ml whole blood in EDTA tube. Stable for 48 hours. For longer periods freeze at –20°C or –80°C

HHV-7 is closely related to HHV-6. Primary infection with HHV-7 usually occurs later in childhood than HHV-6 infection; it can also cause exanthem subitum.

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

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

The Urine Balance Test aims at detecting alterations of the Th1/Th2 balance. The test allows patients and doctors to follow-up on Th1/Th2 balance during therapy and to evaluate whether the treatment is really effective.

C-reactive protein (CRP) is a biomarker of inflammation. Plasma CRP concentrations increase rapidly and dramatically (100-fold or more) in response to tissue injury or inflammation.

Serum-based tests : 2 ml SERUM. Centrifuge immediately after clotting. Keep at ambient temperature or 4°C for 24h. For longer periods, aliquot, freeze and ship frozen.

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.

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.

CD57+/CD3- cells are a subset of NK cells. Their exact function is not well understood but differentiates them from CD56+ NK cells. The absolute number of CD57+/CD3- cells is low in patients suffering from chronic Lyme disease [Stricker et al. 2001].
