Diagnostic relevance of the determination of lymphocyte subpopulations in environmental medicine

Taking all together, the determination of lymphocyte subpopulations in the context of environmental medicine comes under category IV of the criteria of the Commission for Methods and Quality Assurance in Environmental Medicine of the German federal health authority (Robert Koch-Institute; RKI): “A procedure cannot be recommended because there is not sufficient information to justify it” (here: no solid trends in epidemiological examinations), “and because theoretical considerations speak against an application” (here: high physiological variability and missing exposure or substance specificity).
