(5)

“Physical evidence” means any tangible object, thing, or substance relating to a criminal action.

(b)

A law enforcement agency, prosecutor, or court may request a forensic analysis by a crime laboratory of physical evidence if the evidence was obtained in connection with the requesting entity’s investigation or disposition of a criminal action and the requesting entity:

(1)

controls the evidence;

submits the evidence to the laboratory; or

(d)

(1) Except as provided by Subsection (e), a forensic analysis of physical evidence under this article and expert testimony relating to the evidence are not admissible in a criminal action if, at the time of the analysis, the crime laboratory conducting the analysis was not accredited by the commission under Article 38.01 (Texas Forensic Science Commission).

(2)

If before the date of the analysis the commission issues a certificate of accreditation under Article 38.01 (Texas Forensic Science Commission) to a crime laboratory conducting the analysis, the certificate is prima facie evidence that the laboratory was accredited by the commission at the time of the analysis.

obtains accreditation from the commission before the time of testimony about the examination or test.
