Test Code QTB4M Quantiferon TB Gold Plus

Important Note

BLOOD COLLECTION:
 
1. Collect 1 mL of blood into each of 4 tubes.( Tubes fill slowly.)
   When the tube is upright, blood must meet the small black mark on the label.
   Specimens with volumes outside of black mark will be rejected.
2. Immediately shake the tubes firmly 10 times.
   Entire inner surface of tubes must be coated with blood.
   Overly energetic shaking may cause gel disruption and could lead to
   aberrant results.
   Thorough mixing is required to ensure complete integration of the tubes
   contents into the blood. (DO NOT CENTRIFUGE OR REFRIGERATE SPECIMENS)
3. Label tubes appropriately. The label should be placed below colored
   Quantiferon band so back window and black marks are visible on all
   4 collection tubes.
4. Maintain tubes at room temperature (17°C to 27°C) until incubation.
   Do not refrigerate or freeze.
5. Samples must be sent to the Referral Lab for incubation as quickly as possible. Incubation of the 4 tubes must be started within 16 hours of collection.
