What tests are used to study blood stain patterns in CSI?

Blood stain patterns are very important in attempting to reconstruct what happened at a crime scene. These are visual patterns that must be well documented at the crime scene; photographs, notes and all of that. The analysis must be undertaken and it is very important to understand this, by a skilled individual. Somebody who has been schooled in blood stain pattern analysis and has a good deal of practical experience in carrying out these examinations. But these examinations are visual in nature. There are no technological instruments or anything like that that are around, that will allow one to do these kinds of things, other than just looking at the stain with an experienced eye and putting the stain in the context of the entire crime scene.
