The diagnostic value of enzymatic and immunological tests in human trichinellosis.

Abstract

No correlation between the clinical course of trichinellosis and the level of positive titre in immunological tests and total activity of LDH was found. In severe courses of trichinellosis, however, the maxima of total LDH activity appeared earlier. In the described epidemics of trichinellosis the increase in iso-4 and iso-5 of LDH was followed by an increase in LDH activity in 50% of cases, but the maxima in both the biochemical tests appeared 1-6 weeks earlier than the maxima in the immunological tests. For this reason, the biochemical tests could be of diagnostic value in the first weeks of invasion.
