Our O-Tolidine Blood Test Kit is a highly useful presumptive test used to determine whether a suspected stain is blood or not. Often this test is used to confirm the results of a phenolphthalein blood test.

The O-Tolidine Blood Test is administered by first collecting both a positive control using the supplied Known Bloodstain Control and a negative control by testing an unstained sample. Next, a sample of the suspected stain should be collected using either a piece of filter paper or a cotton-tipped swab. One drop of the O-Tolidine reagent, followed by one drop of Hydrogen Peroxide reagent is applied to the collected sample. The results are easy to read: a positive presumptive result causes the sample to turn a deep blue within seconds of applying the reagents.

Our O-Tolidine Blood Test Kit is packaged in a durable, lightweight plastic box for easy and safe transport from one crime scene to another. It includes all the premixed chemicals and supplies required to conduct the o-tolidine blood test. All of the reagents are supplied in plastic dropper bottles for easy use. The kit also includes a Known Bloodstain Control to ensure that the test results are accurate. All kit components are also available to reorder individually as needed.
