This fills a long-standing gap in our repertoire and contains a variety of compounds primarily, though not exclusively, for pleural fluids and for the differentiation of exudates and transudates with a range of fluid markers across the concentration range. A combination of clinical material and in-vitro constructed materials are used to give the best coverage.
