When a sample submitted is sufficient in size to allow a small amount of excess original and/or pretreated sample to be archived, we will archive the sample for a few months following the time of reporting / release of results. This is done as an internal Quality Assurance measure to allow for back-up analyses or additional investigations to be performed, if needed.
Following this retention period, all sample bags and excess sample materials (original and pretreated) will be disposed by incineration.
If you require the return of any unused original or pretreated excess sample materials, your request MUST be made in writing in one of the following ways (we may not be able to honor later requests):
1) At the time of submission
2) Following acknowledgement of sample receipt, or
3) At the time of reporting

– Regular US parcel post (at no additional cost) – Package is not traceable and we have no responsibility outside of shipping it back. Note: We do not send back gas bags and other bulky containers through USPS.
– Federal Express (FedEx) – Package is traceable. Additional charges will be due. Costs will be based on the requested delivery type (Priority Overnight, Standard Overnight, FedEx 2nd Day, and FedEx Express-Saver).
