只有通过模拟血液飞溅的实际实验，才能对与血液有关的犯罪现场有充分的了解和欣赏。由于HIV、B型肝炎和C型肝炎病毒感染频率的增加，使用人血可能会对参与此类实验的人员造成危险。猪（猪）血已被引用的一些作为一个合理的替代品，本文提出了老化的猪和新鲜的人血的物理参数（表面张力，粘度和密度）的比较，在各种条件下，以及液滴轨迹和染色模式的测量。结果支持使用猪血液（长达两周）来代表新鲜溢出的人血的行为。
An informed understanding and appreciation of blood related crime scenes is only achieved through practical experimentation of simulated blood spatter. Because of the increasing frequency of the HIV, Hepatitis B and C viruses, the use of human blood may be hazardous for those involved in such experimentation. Porcine (pig) blood has been cited by some as a reasonable alternative, and this paper presents a comparison of the physical parameters (surface tension, viscosity and density) of ageing pig and fresh human blood, under a variety of conditions, as well as measurements of droplet trajectories and stain patterns. The results support the use of porcine blood (up to two weeks old) in representing the behaviour of freshly spilt human blood.
