Welcome to the Laboratory Information Documentation System (LIDS). This system is the central repository of DCPH-A Laboratory Sciences technical guides, as well as the complete series of the familiar laboratory sample submission, handling, and feedback documents. At this site, customers can access the appropriate technical information, and submit a request for analyses by completing the required information either electronically (preferred) or off-line for transmittal. LIDS documents replace the previously used DCPH-A forms.
