Influence of anticoagulant on the spectroscopic analysis of drying bovine blood pools.

ABSTRACT: Rapidly, untreated whole blood undergoes a clotting cascade, making forensic research that investigates "fresh" bloodletting events difficult. In bloodstain pattern analysis research, whole blood treated with anticoagulant is often used to prolong the usability of the blood and allow for transport and experimentation to simulate pattern formation using "fresh" clot-free blood. Anticoagulants bind to clotting components, making them unavailable to participate in coagulation, preventing the formation of clots. Herein, we investigate the spectral implications of anticoagulant addition for time since deposition (TSD) estimation methods, particularly of larger volume bovine blood pools. We characterized the differences in spectral profiles of blood pools with and without a citrate-based anticoa
