Packaging & Transportation
Courier services are available for transporting specimens to Penrose-St. Francis Health Services (PSF) Laboratory from area locations. Please contact your Client Services or Marketing Representative to arrange for courier services.
If courier services are not available in your area, specimens may be transported to PSF Laboratory via various services, including the U.S. Post Office, bus, or airline services. Contact your Client Services or Marketing Representative for help in selecting the most appropriate routing for your specimens.
Please note: All specimens MUST be properly packaged for shipping by the client. It is imperative that all specimens are packaged in such a manner that prevents leakage and contains any accidental leakage or contamination. Refer to the most current CDC regulations. PSF Laboratory furnishes shipping supplies to clients as appropriate.
Specimens for which the test catalog indicates "room temperature" or "ambient temperature" may be transported in the standard shipping containers. Place the specimen into a tightly-sealing plastic bag to contain any leakage. When outside temperatures are extreme, specimens may need to be insulated to avoid freezing or overheating.
Specimens for which the test catalog indicates "refrigerated," "wet ice," or "coolant shipment" must be transported with a FROZEN COOLANT PACK. Place the specimen in a tightly-sealing plastic bag; place a paper towel or other buffer between the specimen and the coolant pack; place both into the Styrofoam® shipping container supplied by PSF Laboratory.
Specimens for which the test catalog indicates "frozen" shipment, must be frozen prior to packaging for shipment. Place the frozen specimen in a tightly-sealing plastic bag. Place the bag into the Styrofoam® shipping container supplied by PSF Laboratory, and send the specimen on dry ice.
The laboratory tests are performed on anticoagulated whole blood, plasma, or serum.In general, specimens should be refrigerated until placed in the courier box for transport to the laboratory.Please see our individual test directory section for specific requirements.
- Plasma: Draw a sufficient amount of blood with the indicated anticoagulant to yield the necessary plasma volume.Gently mix the blood collection tube by inverting 6-10 times immediately after draw.If required, separate plasma from cells by centrifugation within 20-30 minutes.
- Serum: Draw a sufficient amount of blood to yield the necessary serum volume.Allow blood to clot at ambient temperature, and then, separate serum from clot by centrifugation within 20-30 minutes.Caution: avoid hemolysis.
- Whole Blood: Draw a sufficient amount of blood with the indicated anticoagulant.Gently mix the blood collection tube by inverting 6-10 times immediately after draw.
