Abstract
A method for detecting the presence of carboxylic acids in a specimen is provided. A specimen is contacted with a developing system containing a metal salt reactive with carboxylic acids present in the specimen to form metal-carboxylic acid complexes. Any such complexes are colorimetrically detected by their activity in catalyzing oxidation of a chromogen such as guaiac. The method is useful in detecting intestinal helminth infestation.
