Collection Requirements
1 mL whole blood collected in each of the following tubes: QFT-Nil control (gray cap white or gold ring) tube; QFT-TB1 antigen (green cap white or gold ring) tube; QFT-TB2 antigen (yellow cap white or gold ring) tube; QFT-Mitogen control (purple cap white or gold ring) tube Instructions: For each patient collect 1 mL of blood by venipuncture directly into each of the 4 QFT-PLUS blood collection tubes. These tubes should be at 17-25 deg. C. at the time of draw. If a 'butterfly needle' is being used a 'purge' tube should be used to ensure that the tubing is filled with blood prior to the QFT-PLUS tubes being used. Immediately after filling the tubes shake them 10 times just firmly enough to ensure the entire surface of the tube is coated with blood to solubilize antigens on tube walls.

Shipping Instructions
Each of the four tubes must be transferred to a 37 deg C. +/- 1 deg. C. incubator as soon as possible and within 16 hours of collection for 16-24 hours. If the blood is not incubated immediately after collection re-mixing of the tubes by inverting 10 times must be performed immediately prior to incubation. The specimen rack should sit off the floor of the incubator and the tubes should be upright. Following incubation either: A. Centrifuge each of the 4 incubated collection tubes for 15 minutes at 2000-3000 RCF(G). Label with patient name identification number and date of collection. Deliver to Quest Diagnostics at 2-8 deg. C. Samples will be stable for 28 days at 2-8 deg. C. (refrigerated). or B. Immediately transport the 4 collection tubes to Quest Diagnostics between 4 and 27 deg. C. Samples will be stable for 72 hours at 4-27 deg. C. (refrigerated or at room temperature). Note: Specimen collection locations >3350 feet above sea level should use the QuantiFERON(R) collection kit designed for 'High Altitude' (tubes with a gold ring on tube top).
