Whole Blood: Specimens requiring whole blood are collected in EDTA containing royal blue-top evacuated tubes, free of the trace element in question. Patients should refrain from taking vitamins, mineral supplements or antacids at least three days prior to specimen collection.

Be sure to confirm that the specific tubes used are free of the trace element in question. Avoid royal blue-top tubes containing heparin since the specimen frequently will gel or develop micro clots over time. Firmly replace the cap on the lavender-labeled vial and ship the specimen refrigerated. Centrifuge the tube and pour the plasma into a plastic trace element shipping container. Be sure to gently mix the specimen promptly after phlebotomy. Acid-washed shipping containers (lavender-labeled) are available for determinations of aluminum, chromium, manganese, selenium, copper, and zinc in plasma. Many commercially available royal blue-top tubes are suitable for zinc and copper determinations in plasma. Plasma: Royal blue-top evacuated tubes (EDTA) certified free of the trace element in question are required for specimen acquisition arid transport. Firmly replace the cap on the red labeled vial and ship the specimen refrigerated (2-10☌).

Use powderless gloves as part of standard precautions. Pour the serum into a plastic trace element shipping container (red label). Centrifuge the tube at 800-1000 g for 10-15 minutes, at room temperature. (See individual test requirements.)Īllow the specimen to clot at room temperature (15-30☌) for 30 minutes. A trace element serum collection package is provided containing acid-washed shipping containers (red label) and royal blue-top tubes (red label) suitable for aluminum, chromium, manganese, selenium, copper, and zinc in serum. Please note that not all commercially available royal blue-top evacuated tubes are suitable for aluminum and selenium determination.
