La. R.S. 13:5719

Any parish or municipality may establish a laboratory for the use of the coroner. In any parish where there is no coroner's laboratory, the coroner may contract with the coroner or laboratory of another parish to perform such examinations, analyses, or tests as he deems necessary and advisable. The fees for such examinations, analyses, or tests shall not exceed those customarily charged in other similarly qualified laboratories. The fees shall be paid by the governing authority of the parish of origin on approval of the coroner of that parish.
