Quantiferon TB Panel (not pre-incubated)
MessageBHS and Bedford send most of their quantiferons site incubated to Chantilly using code 16603. If a sample cannot be incubated this test can be used.
Test Code
QUANTIFERON TB PANEL(O).
Preferred Specimen
Special collection kit of three tubes.
Minimum Volume
Exactly 1 mL in each tube
Instructions
1. For each patient, collect 1 mL of blood by venipuncture directly into each of three unique QuantiFERON®-TB Gold IT blood collection tubes. Tubes must be at room temperature prior to collection. Under or overfilling of the tubes may lead to erroneous results.
2. Shake them ten times just firmly enough to ensure the entire surface of the tube is coated with blood, to solubilize antigens on tube walls.
3. Transport specimen at room temperature to the laboratory immediately or within 16 hours.

Clinical Significance
tuberculosis is a communicable disease caused by infection with M. tuberculosis complex. Infection results in either acute disease or Latent TB Infection (LTBI), a non-communicable asymptomatic condition. The main purpose of diagnosing the latent stage is to consider medical treatment for preventing overt disease. Until recently, the tuberculin skin test was the only available method for diagnosing LTBI. QuantiFERON®-TB gold eliminates false positive skin test due to BCG vaccination and most Non-Tuberculous Mycobacteria (NTM) and is an objective, reproducible qualitative test. There are no side effects or adverse reactions due to patient hypersensitivity, and no "booster effect", whereby the first test induces a false positive response on re-testing. There is no need for follow-up patient visits to obtain test results.
