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.
A single blue line means the testing liquid is working fine but no human blood has been
detected, two blue lines mean the test has detected human blood.

Principle:
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.
