Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Qualitative determination of: - Pigments - Metals, which may be part of the pigment or present as impurities - Patch testing of pigments in order to identify clinically relevant allergens - In vitro characterization of T cell-mediated inflammatory reactions to metals and pigments using membrane-bound proteins Correlation of the analysis results with - results of patch testing (allergy history using IVDK/Winalldat software) - clinical history data / exposure data recorded with the help of the accompanying information , e.g. histopathological diagnoses - results of laboratory tests of specific T-cells from blood samples (flow cytometry) - with further clinical data (allergy history with the help of IVDK/Winalldat software) - with anamnesis data of the additional questionnaire ("extended body art anamnesis") | — |
Secondary
| Measure | Time frame |
|---|---|
| (Semi-)Quantitative determination of - pigments - Metals, which may be part of the pigment or present as impurities - binders (e.g. (meth)acrylates), which are present as a component of the color or as an impurity (monomers) Correlation of analytical results with - laboratory results - the declaration and chemical analysis of the ingredients in the liquid tattoo inks used (if available) Evaluation of inflammation markers and lipid structure of the pigment surrounding tissue Identification of individual risk factors by TZR sequencing and HLA genotyping and evaluation of their suitability as differential diagnostic molecular markers. | — |
