Testing of QBC hematology tubes and QBC Malaria Test tubes promptly after centrifugation is recommended.
The delays below, however, will not affect test results.

4 hours after centrifugation. Store the tubes vertically, stopper down in the tube rack, away from heat and
intense light. Consult the applicable QBC System Operator’s Manual for test instructions.
• QBC Malaria Test: After centrifugation, QBC Malaria Test tubes can be held for as long as 3 days unrefrigerated,
at temperatures up to 37 ºC (99 ºF), before microscopic examination. Store tubes vertically, closure down in
the tube rack.
