BLUESTAR OBTI is the perfect complement to BLUESTAR® FORENSIC.

This rapid screening test presumes that a bloodstain is of human origin. This helps the investigator to choose to collect or not a sample as evidence. A positive result indicates a strong likelihood for the presence of human blood. A lab analysis will later confirm or infirm this presumption.

BLUESTAR® OBTI is an evolution of Hexagon OBTI. Both products are identical in their formula, production site, quality and care given to their production.


  • BLUESTAR® OBTI is a two-part test: a collection tube for the blood sample, and a test bar.


  • A sample of the presumed human blood trace is transferred into the tube with transport medium. This mixture is added drop by drop to the test. A positive sample is typically detected within 2-5 minutes.
  • A single red line means the testing liquid is working fine but no human blood has been detected, two red/pink lines mean the test has detected human blood.


  • All the components of the BLUESTAR® OBTI test have to be stored in a dry place with temperature range comprised between 2°C (35.6°F) and 30°C (86°F).
