Your question is an important one! For evidence to be useful in the legal system, it must first be properly collected and preserved. If this is done correctly, then ideally, a reliable link can be made between a suspected perpetrator and a crime.
Blood is a common type of evidence and this evidence should never receive exposure to intense heat or humidity. In fact, it should be refrigerated until it is brought to a crime laboratory.
Blood might be lifted by tape or it might be scraped and then preserved on a cotton square. Blood can also be absorbed onto threads. Evidence items that are bloodstained may be packaged into a bag or envelope to prevent contamination with another piece of criminal evidence or surrounding objects.
