Sample Preservation and Tracking
- Please contact the laboratory prior to shipping or delivery of samples to arrange for receipt and proper storage.
- Please type and use the shipping label, chain of custody, and sample data forms provided (see related files at right) for all samples being analyzed.
- Samples may be refrigerated, but DO NOT FREEZE samples or allow samples to become frozen during shipment. A freeze indicator can be included in the sample crate if shipping from a cold environment where this may be a concern.
- Please ship samples in a padded crate. Remaining sample can be returned in its original container upon completion of analysis if a FedEx or equivalent shipping account number is provided; otherwise, remaining samples will be discarded 90 days after completion of analysis unless arrangements are made for pickup.
