Reference Samples
To compare the victim's or suspect's DNA profile to the recovered crime scene DNA, the laboratory will need to have their known biological samples available for a side-by-side comparison. These known samples are called reference samples.
Many forensic laboratories will not examine the evidence unless reference samples are provided.
