The tubes listed above are but a few of the specialty tubes used in venipuncture.
Make sure you check with your facility lab for any tubes you are unfamiliar with.
The Quantiferon tubes are normally drawn in a set of three. A grey, red, and purple. Some facilities may also use the Quantiferon Gold test, which is more precise and adds a fourth tube which is gold in color.
Be sure and check with your facility for the correct order for the Quantiferon, as it may differ between facilities.
