DNA: Sample Storage
Storage of
extracted DNA
Extracted samples are considered evidence. DNA extracts will be barcoded
andwill be stored in freezers located in the extraction area.
Storage of
amplified DNA
Amplified samples are considered work product and will be stored in a
freezer located in the amplification/ typing room.
ve
d
Amplified DNA from casework will be retained in frozen storage until the
case has been technically and administratively reviewed. After the review
process has been completed, the amplified DNA may be destroyed.
NOTE: Exceptions to this process are when
 the entire evidence sample was consumed in the analysis
 the entire amount of extracted DNA was used for amplification.
Ar
ch
i
For either of these exceptions, the amplified DNA will be retained until
authorization to destroy is received from the District Attorney’s Office.
