I want to give an update on the previous posts about luminol (aka Bloodglow).
A friend had disappointing results with it this season. I'd given him some packets with the expired activator and also instructions (from Jerry Allen) on how to substitute peroxide when the activator tablets have an expired shelf life. My friend mixed the luminol tablet and the peroxide with the recommended amount of windshield fluid. It made 24 oz. He could not find a glow along the trail where the wounded buck ran.
So I mixed up the same solution (expired activator, windshield fluid and peroxide, 24 oz total) and tested it on blood from a deer steak. I did have a glow but not a great one.
FFWD to this weekend and we did another test. Same mix ratio as Jerry recommended (with the peroxide). We got almost no glow. So, the next morning, we added another luminol tablet and a little more peroxide to the half used mix we already made and we returned to our mock blood trail. the glow was now quite substantial and easily seen and followed.
So, what our experiences this year prove, I can't say for sure. I am highly suspicious that the directions with the luminol may suggest a mix ratio that's a little weak. I'm not sure that the tablets mixed with 24 oz of fluid is strong enough. I also realize that the peroxide can work as a substitute for an expired activator tablet, but does it work as well as a fresh, un-expired activator tablet?? I don't know.
I have ordered a new package fro Jerry this morning. When it arrives, I will do some more tests with mock blood trails. I will keep you guys informed about the results.
I do still believe luminol is an effective tool for locating microscopic blood, but there does seem to be some mixed results at times. As always, this stuff is just another tool and is no substitute for ethical shots and solid blood trailing skills. But when the visible blood runs out or gets rained out, then luminol may mean the difference in finding or losing an animal.
