Jersey has not considered the admissibility in a case of the results of the phenolphthalein presumptive test for the presence of blood on a person or object or any other presumptive test utilized for that purpose. Nonetheless, in this case, evidence of a positive result was introduced, without objection, by a police detective with no prior experience in conducting the test and no understanding of how it functioned or of the possibility of false positive results occurring as the result of the presence of substances other than blood. We found the introduction of the test results to constitute reversible error, and in the course of our discussion of the issue, canvassed precedent from other states discussing the conditions for admissibility of the phenolphthalein test and other presumptive tests for the presence of blood.
