My hypothesis was not totally supported because Bluestar had a higher luminance MOST of the time,but not ALL of the time, which is what I expected. Luminol was higher in 2 bloodstain removal methods, Comet and in the Water/Paint. Those were the two drywall squares where you could see the smallest amount of blood left. I think that Luminol works better when there are very small amounts of latent blood present. Bluestar was higher in the Control, Windex, Dawn and Bleach/Water samples. Now came the T Test to see if the results were significant for scientific purposes. Comet did NOT PASS the T test, so that means that the difference between Bluestar and Luminol was not statistically significan and it doesn't count. For scientific purposes, there was NO difference between the luminance of Bluestar and Luminol. The results of the other areas were statistically significant...Bluestar had a higher luminance in the Control, Windex, Dawn and Bleach/Water samples, and Luminol had a higher luminance in only the Water/Paint samples.



No matter what the readings said on the light sensor, ALL of the samples with latent blood glowed, so these light detection sprays always worked.
