The C.O.C.s submitted with the samDles do not indicate a method of Dreservation. However
the lab intake sheets indicate the samples were received at or below 6 degrees Celcius. If the
samples are shipped on ice and no other preservative is used, please indicate the method of
preservation as ice on the C.O.C. The C.O.C. is considered as a legal document. A hand
written note on the C.O.C., indicating Ice as the preservation method is acceptable.
