Phenolphthalein and Leucocrystal Violet Combination Kit

The combination of these two tests is used as a presumptive test and confirmatory test for the presence of blood.  This kit is packaged in a plastic box containing all the premixed chemicals and supplies required to conduct both the Phenolphthalein Presumptive Blood Test and the Leucocrystal Violet Test.  The premixed liquid reagents are in plastic dropper bottles. 

A non-human known blood standard is included to monitor the results.
