The examination for Bloodstain Pattern Analysis Certification is divided into four (4) sections. Six (6) hours are allotted to complete the entire examination. Each part/section will be graded separately. All four sections must individually be passed with a 75% on each section to pass the certification test.
Type: Blood typing can be used as an initial test to exclude some suspected sources of a bloodstain. For example, if a blood stain at the crime scene contains Type A blood, but the key suspect has Type O blood, the suspect could be excluded as a source of the blood stain â meaning he or she definitely did not leave the blood stain. However, blood type alone usually cannot positively identify a suspect because many people share the same blood type. Investigators have collected blood samples from each of the suspects in the case. The samples and the evidence are labeled A-D.
