FIELD: chemistry.
SUBSTANCE: diagnostic test element (110) for the detection of an analyte in a sample (126) of a body fluid, in particular whole blood with the volume not less than 2 microlitres, contains a test field (116) with a reagent-indicator, where the reagent-indicator is capable of feeling a detected change, in particular an optic change, in case of the analyte presence. The test field (116) includes a detector layer (118), containing the reagent-indicator, where the detector layer contains particles (137). 90% of all particles (137) of the indicator layer (118) have the actual size smaller than 10 microns. The diagnostic test element (110) contains a bearing element (112), which has a transparent region (114), where the test field (116) with its detection side (120) is partially applied on the transparent region (114).
EFFECT: detected change is an optically detectable change, where an optic detector with spatial resolution is applied for the detection of the detected change.
