Cleveland Clinic Laboratories will only accept the QuantiFERON-TB Gold Plus (QTB-Plus) 4-Tube Assay for Mycobacterium tuberculosis testing (Normal: INFTBG, INFINC; High Altitude: INFTBP, INTPGP)

New QuantiFERON-TB Gold Plus Collection Tube Kits have a total of four (4) blood collection tubes instead of three.

Regular and High Altitude tubes are available to order from the Supply Storefront.

Please note: Prior to collection, tubes must be stored at 4° to 25°C.

Important Details

Line draws will no longer be accepted.
•  Venipuncture is the only acceptable draw type.

New order codes will be listed in the Test Directory on September 12, 2018.
• Collection sites, processing, handling, and incubation specifications will remain the same.

All unused 3-Tube QuantiFERON Kits should be returned to our laboratories.
• Tubes can be given to couriers or transport can be arranged through Client Services.

Specimen Validity Testing (SVT) analytes have a stability of up to 5 days at 2 – 8 °C, as stated in the Instructions for Use (IFU).

Based on the laboratory’s studies, this stability is based on samples that have reached an equilibrium.

• Introduction of oxidants to a urine sample will not be stable until an equilibrium is achieved.
• Time to reach equilibrium will vary dependent on the type and amount of oxidant used as an adulterant.
