The advantages of the VACUETTE® FC Mix Tube are clear:

• Stabilisation immediately after collection for 48 hours
• Based on the in vivo value (almost 100%)
• Avoids false-negative diagnoses of diabetes patients
• Stabilisation allows for longer transport and storage times

Inhibition via sodium fluoride

In order to extend the inhibition to 48 hours, the tube contains a sodium fluoride additive.

No conversion factor

Unlike additives added in liquid form, the powder additive in the VACUETTE® FC Mix tube has no dilution effect. There is, therefore, no need to take a conversion factor into consideration. Inverting ten times ensures that the tube additive is completely dissolved and therefore well mixed with the sample.

After correct inversion, FC Mix tubes can be stored 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 immediately 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 of glucose stabilisation.
