Blood Pattern analysis (BPA)

Advances in DNA profiling and the acceptance of DNA evidence leads to new questions - not whose blood is it but how did it get there? Cellmark's analysts can determine information from BPA which can siginificantly impact on a police case.

Analysis of blood patterns can deduce:

• The bloodstain's point of origin
• Type of "weapon" used which resulted in the bloodstain
• Was there a single blow or a multiple attack
• Speed and direction of blood flow
• Authenticity of a witness or suspect's statement
