Special Set of Collection Tubes (obtained from PCL Clinical Lab)

Collect 1 mL into each of 3 Cellestis QuantiFERON Gold collection tubes for High Altitude (HA). Carefully follow the instructions below:

1. Tubes must be drawn in the following order:  
   1. GRAY (Nil HA)
   2. RED (Antigen HA)
   3. PURPLE (Mitogen HA)
2. If other blood work is requested, collect the QuantiFERON tubes LAST. If a butterfly is used, use a purge (throw away) tube so the tubing does not take up any of the required 1 mL volume in the first tube.
3. Draw 1 ml into each tube and fill exactly up to the black line. **DO NOT OVERFILL OR UNDERFILL TUBES**.
   • Expect relatively slow blood draw time; keep tube and needle in place for 30 seconds after tube appears to have completed filling to ensure correct volume is collected.
4. Shake tubes firmly 10 times just enough to ensure the entire inner surface of the tube is coated with blood and to dissolve the antigens on the tube walls.
   • Avoid overly vigorous shaking- it may cause gel disruption and aberrant results.
5. Label each of the three tubes and include the time of collection.
6. Maintain tubes at ambient temperature.
