#laboratory analysis
- Achromatophilia — The property or characteristic of certain cells, tissues, or microscopic anatomical structures to be achromatophilic, displaying a total resistance or complete lack of affinity toward standard biological stains. In laboratory techniques, this structural biochemical condition prevents pigment fixation, leaving samples colorless after exposure to reagents.
- Adenogram — The written result, graphical representation, or quantitative and qualitative microscopic interpretation of the cells obtained by fine-needle aspiration of a lymph node or a gland. This structural laboratory investigation (also known as a lymphadenogram) establishes the percentage ratio between different cell types (lymphocytes, neutrophils, histiocytes) to differentiate an inflammatory reaction from a malignant proliferation.
- Ariat — A rare technical term used to describe a chemical compound or a salt derived from a specific acid or a crystalline structure analyzed in applied mineralogy laboratories.
- Arimat — A rare technical term or chemical compound from the class of salts or structural aromatic derivatives analyzed in advanced organic synthesis processes; belonging to or containing a structure from a specific aromatic radical.
