Common questions

Does a positive HemaTrace result prove the stain is human blood?+

It is a strong presumptive indicator, but documented cross-reactivity with ferret blood and some higher-primate blood means a positive result is not absolutely species-exclusive, so it is typically followed by DNA typing for confirmation.

Where does this test sit in a bloodstain examination workflow?+

It is used as a rapid presumptive or species-confirmatory screening step, applied before committing a stain to more time-consuming and sample-consuming DNA analysis.
