BIOTECH is the only reference laboratory that offers QuantiFERON-TB Gold Plus blood collection with a single lithium heparin tube.
Benefits and Advantages:
• Very convenient one tube option specimen preparation. Processing is performed entirely at Biotech Clinical Lab.
• Clinical specificity at 97.28% and better clinical sensitivity at 94.09% (compared to the 3 tube option)
• Lower percentage of indeterminate results for less risk
• CDC recommends interferon γ release assay (IGRA) over tuberculin skin test (TST)
Specimen Collection
Blood may be collected in a single blood Collection tube containing Lithium-Heparin as the anticoagulant, provided by Bio-Tech Clinical Laboratory. Only use lithium heparin as a blood anticoagulant because other anticoagulants interfere with the assay.
Label tube appropriately with Patient Name and Date of Birth. Be sure to register time and date of the blood collection in the laboratory request form.
Important: Blood collection tubes should be at room temperature (62.6-77 Fahrenheit) at the time of blood collection.
Fill a Lithium-Heparin blood Collection tube and gently mix by inverting the tube several times to dissolve the heparin. This procedure should be performed by a trained phlebotomist.
Lithium-Heparin blood Collected tube must be maintained at room temperature (71.6 +/- 9 Fahrenheit) until Bio-Tech Lab picks up the specimen.
Warning: Over vigorous shaking may cause aberrant results.
