Louisiana Revised Statutes Tit. 15, § 621. Prohibition on destruction of evidence; certain cases

(1) “Biological evidence” means the contents of a sexual assault examination kit or any item that contains blood, semen, hair, saliva, skin tissue, fingerprints, or other identifiable human biological material that may reasonably be used to incriminate or exculpate any person in the criminal investigation, whether that material is catalogued separately on a slide or swab, in a test tube, or some other similar method, or is present on clothing, ligatures, bedding, other household materials, drinking cups, cigarettes, or any other item of evidence, including those that are alleged to have been touched or worn by the perpetrator of the offense. Work product generated during DNA analysis shall not be considered biological evidence with the exception of the extracted DNA when the original biological evidence is consumed during analysis. In this event, the extracted DNA shall be retained.
