    INTROL™ TB PANEL M114:
 
Product Name

INTENDED USE:
INTROL™ TB Panel M114 is intended for use as a quality control to monitor analytical performance of M. tuberculosis (MTB) on the GeneXpert® System. INTROL™ TB Panel M114 is formulated to monitor the detection of MTB and multi-drug resistant MTB (MDR-TB) mutations.

The World Health Organization (WHO) reports that one-third of the world’s population is infected with MTB.1 In 2009, 1.7 million people died from tuberculosis (TB) and 9.4 million new cases were reported.  MDR-TB is increasing with some regions reporting as much as 28% of new TB cases are MDR-TB.2

INTROL™ TB Panel M114 is provided for Research Use Only (RUO). It cannot be cloned, sold, or transferred without the explicit written consent of MMQCI.

PRODUCT SUMMARY and PRINCIPLE:
INTROL™ TBWT-04 and TBMDR1-04 of INTROL™ TB Panel M114 consist of non-infectious, synthetic MTB DNA encapsulated in chemically fixed and killed bacterial cells. The MTB DNA does not include the entire MTB genome but is comprised of the following MTB gene segments: IS6110, hsp65, 16S rRNA, 23S rRNA, inhA, katG, and rpoB. Drug resistance mutations are incorporated in segments inhA, katG, and rpoB, as indicated in Table 1.

Best practice is to establish a quality control program for every assay performed by the laboratory.3, 4 Routine use of quality controls that are consistent lot to lot and monitor the entire assay assists the laboratory in identifying shifts, trends, and increased frequency of random errors caused by variations in the test system, such as failing reagents and pipetting errors. Early investigation can prevent failed assay runs.

COMPOSITION:
INTROL™ TB Panel M114 is available in two kit configurations.  M114-10 is comprised of 10 kits; each kit is comprised of three bottles, 1 mL each and M114-5 is comprised of 5 kits; each kit is comprised of three bottles, 1 mL each. Two bottles contain encapsulated MTB DNA, gene segments IS6110, hsp65, 16S rRNA, 23S rRNA, inhA, katG, and rpoB. The third bottle contains buffer and preservative only. The cells encapsulating the MTB DNA are suspended in buffer with preservative. The presence or absence of drug resistance mutations is specified for each bottle in Table 1.

PRECAUTIONS AND WARNINGS:
INTROL™ TB Panel M114 is for use on the GeneXpert® System only. It cannot be cloned, sold, or transferred without the explicit written consent of MMQCI. This product does not contain any biological material of human origin or infectious microorganisms. Do not freeze.

STORAGE and STABILITY:
Upon receipt and after opening, the material should be stored at 2° – 8°C.  Do not freeze.
Unopened controls are stable through the expiration date printed on each bottle when stored at 2° – 8°C. Opened material tightly capped and returned to the refrigerator (2° – 8°C) shortly after use is stable for thirty (30) days from the date of opening.

INSTRUCTIONS FOR USE ON THE GeneXpert® System:
1. Each bottle contains 1.0mL of control material.
2. Allow controls to come to room temperature.
3. Thoroughly mix controls by vigorously inverting several times immediately before use.
4. Before opening bottle, shake down or tap bottle on hard surface to be sure all liquid is out of cap.
5. Add 2 mL Sample Reagent to each control vial.
6. Mix by inverting the vial 10 times.
7. Let the vial sit at room temperature for 15 minutes.  Invert several times half way through incubation period as you would for a sputum sample.
8. Open the Xpert® MTB/RIF cartridge lid and transfer 2.0 mL of respective Sample Reagent treated control, using a sterile transfer pipette. Close lid.
9. Transfer cartridge to the GeneXpert system.
10. Scan cartridge, enter sample ID and start the run.

LIMITATIONS:

INTROL™ TB Panel M114 is designed for use with MTB amplification assays that target one or more of the following MTB gene segments: hsp65, rpoB, 16S rRNA, 23S rRNA, inhA, katG, and IS6110. Only those segments are present in INTROL™ TB Panel M114.
