Before you spend a large amount of time on a red stain that
appears to be blood, do a simple check to make sure it is blood.
Bloodstain Green is a new QuickCheck product to detect blood
(does not distinguish between animal and human blood).
To
use, first identify a suspected bloodstain or blood spatter.
Take the included swab and collect a small sample. (With a dry
stain, it is best to moisten the swab tip with sterile distilled
water.
With
the QuickCheck protective sleeve in place break the lower ampoule.
Then slide the sleeve up and break the second ampoule. Tap your
finger on the side of the tube to mix, then squeeze out 1-2 drops
of the mixed solution with the applicator tip directly on the
swab tip.
If
its blood, the swab tip where the sample you swabbed will quickly
change to a bluish-green color within seconds indicating that
this is blood.
A way to document what you
have done is to place the
swab near the stain and take a picture showing the stain
and the test result showing it positive for blood.
When completed with the test place the swab and ampoule tube
in the disposal bag and discard.
The PathFinder can be purchased through the Lynn
