Immunochromatographic test for confirming the presence of human blood traces.

When processing a crime scene and you have a red substance that is possibly blood but you are not sure or working with possible blood spatter in the past we could check the red substance using a presumptive test for blood which is not specific to human.

Hexagon OBTI is the perfect complement to determine if the red sample is human blood.

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 the bloodstain is human blood.

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.

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.

The Intergi Swab can be purchased through the Lynn Peavey Company.
