Many clinical laboratories utilize reference (or referral) laboratories for molecular methodology testing. Transport and shipping of biological specimens must follow laws and regulations governing these types of specimens.
Consult your laboratory's accrediting agency and reference lab for specific policies and procedures.
Always consult the procedure for the proper temperature and proper transport container as swab and tissue specimens must be submitted in the appropriate transport medium and tube. In many cases, plastic tubes are required to be "Rnase- and Dnase-free" tubes.
