Blood stain analysis is an important area in crime investigation; which might get affected due to many condition. In present study the blood stains were prepared on different fabrics and then placed in different environmental conditions (different temperatures and pH) and was analyzed by chemical reagent (phenolphthalein). We found that the adverse temperature conditions interferes in identification of blood stains and it should be taken into consideration while analysis.
