The specialty tube is not normally drawn with other tubes in order to avoid contaminating the test.
The following is a sample of some of the most common specialty tubes:
|Royal Blue-Red||Clot Activator (Serum)|
Most of the specialty tubes are drawn with a separate device and using a separate venipuncture sight if other tubes are being used.
The tubes and associated test are as follows:
|Royal Blue-Red or Lav||Trace elements, Nutrition, and Toxicology|
|Orange||Stat Serum Chemistry|
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.
