Hexagon OBTI

What is it?

HEXAGON 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 2-3 minutes.

Principle:
Hexagon OBTI test and control lines Human hemoglobin (hHb) in the sample reacts with a reagent consisting of blue colored particles and monoclonal anti-human Hb antibodies. The immunocomplex migrates to the test zone where it is captured by an immobilized second antibody directed against hHb forming a blue test line to indicate a positive result. Unreacted reagents migrate further and are bound in a second line by immobilized anti-mouse lgC antibodies. This control line indicates proper function and correct handling of the test.

The test detects whole blood up to a dilution of 1 : 1,000,000. As little as 500 red cells are required for a positive result.
