QuantiFERON(R)-TB Gold Plus is an indirect test for M. tuberculosis infection (including disease) and is intended for use in conjunction with risk assessment, radiography and other medical and diagnostic evaluations.

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(R)-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.

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 collection kit designed for
"High Altitude" (tubes with a gold ring on tube top)
