1. A dry analytical element for the determination of total lactate dehydrogenase (LDH) comprising a support having thereona porous spreading layer composed of a particulate structure comprising a plurality of particles being bonded to each other on surface areas of said particles which are adjacent, where said adjacent particles form a coherent, three dimensional lattice which is essentially non-swellable to an aqueous liquid,said element further comprising a saturated or unsaturated fluorinated surfactant containing one or more fluorocarbon moieties each having from 4 to 16 carbon atoms and from 8 to 33 fluorine atoms, and each of said moieties having a ratio of fluorine atoms to carbon atoms of about 2:

  • 1, provided that when said surfactant contains more than one such moiety, said moieties have up to two fluorinated or unfluorinated methyl branches.
