Shipping Instructions


  1. Pack your specimens as usual. If your specimen needs a coolant, use a frozen ice pack but do not use dry ice.

  2. Call Federal Express toll free at 1-800-238-5355 or 1-800-GO FEDEX to request a pick-up. Some remote areas have pick-ups earlier in the day to insure next-day delivery so be sure to ask when your specimens should be ready for pick-up.

  3. Tell the customer service agent you are sending your specimens to our FedEx account, and that you will need a diagnostic specimen pack and airbill for your sample (if necessary). Call 970-491-1170 or 970-297-1281 to ask for our FedEx number. Be sure to request Standard Overnight service and check off "Recipient Box" for Payment. Also be sure and record the weight on the form.

  4. The cost will be added to your accession's test charges and will be reflected on your sales service invoice and statement.

  5. You may request either Saturday pick-up (for Monday delivery) or Saturday delivery (with Friday pick-up). Samples picked-up Friday without a special request of Saturday deliver will arrive on Monday morning. Please be aware that there will be an additional $10.00 charge added to your sales service invoice for either Saturday pick-up or delivery. If it is necessary to send flow cytometry samples over the weekend (we discourage this), they must be delivered on Saturday so they can be refrigerated.

  6. Lab packs are available at no charge by calling 1-800-GO FEDEX and pre-printed airbills are available by calling the CSU Diagnostic Lab at 970-297-1281.
