Product Handling Update: Instruction for use of FC Mix Tubes

Our internal studies have reconfirmed that the mixing of the FC Mix Powder is critical for the long-term stabilization (up to 48 hours) of glucose in these tubes. Since we cannot guarantee that the inversion of the tubes (10x) is strictly followed by all of our customers and hence to ensure the integrity of the correct glucose stabilization in the samples, we have decided to revise our current Instruction For Use of the FC Mix tubes. The revision is also based on the fact, that the correct mixing of the FC Mix tubes is essential for the stabilization of the glucose for 48 hours.

  • FC Mix Tubes (Primary Tubes) can be stored after correct inversion for up to 24 hours at room temperature without centrifugation. 
  • Should the tubes be expected to be stored longer than 24 hours at room temperature, samples should be centrifuged after blood collection in order to be stored for up to 48 hours at room temperature.
  • Centrifuged aliquots from FC Mix Tubes can be stored for up to 48 hours at room temperature. Tubes should be centrifuged as soon as possible.
  • Cooling of the samples (4-8°C, 39–46°F) is also suitable for 48 hours glucose stabilization.
