  • Hexagon OBTI

    Hexagon OBTI is simple to use with results in less than three minutes. Human hemoglobin (hHb) reacts with the conjugate composed of blue particles and monoclonal anti-human hemoglobin antibodies. This screening test rapidly verifies if a bloodstain is human blood. Hexagon OBTI contains a two-part test: a collection tube for the blood sample and a test bar. Directions A sample of the presumed human blood trace is transferred into the tube with transport medium. With the lid screwed back on, shake the sample gently inside the transport medium. This mixture is added, drop by drop, to the test in the sample well (S) at the lower end of the test. A positive sample is typically detected within 2-3 minutes. Negative results should be confirmed after 10 minutes.
