Leucocrystal violet is the completely reduced form of crystal violet. The dye powder appears white to gray to lavender, and solutions are expected to be colorless. In addition to identifying lactobacilli in cheese, Leucocrystal Violet (LCV) is a cationic triarylmethane dye that has an affinity for both cellulosic and proteinaceous materials. It reacts with the hemoglobin in blood and turns the blood impression to a purple/violet color. Consequently, the dye is widely used to stain blood residue on both porous and non-porous materials. There is also mention of Leucocrystal Violet being used as an indicator on a urinalysis test strip, potentially to detect the presence of blood or protein. However, the quality level for Leucocrystal Violet is 200 on a scale of 100 to 600, and it is only advertised as suitable for Research Use Only. Urinalysis test strips sold for human use are classified as medical devices and are stated to be suitable for In Vitro Diagnostic Use. As such, product 219215 is not suitability tested to ensure the dye is suitble for use in the manufacture of urinalysis test strips.
