QuantiFERON-TB Gold In-Tube

Mixing of Blood Collection Set

November 2009

The tubes should then be placed in a 37ºC incubator as soon as possible, and definitely within 16 hours of collection. However, I would encourage laboratories to place the tube set into the incubator as soon as they have been mixed and labeled. If for some reason you’re unable to incubate immediately, maintain the tubes at room temperature until they can be incubated. And if the tubes are not immediately placed at 37ºC, you should repeat shaking vigorously for 5 seconds immediately prior to incubating at 37ºC. One additional important note is that the tube set should not be refrigerated or frozen prior to incubation.
