Cap with white ring ) Follow directions for lithium heparin tubes below other quantiferon mitogen minus nil normal range QFT. A test is indeterminate if the Nil value is >8.0 IU/ml or if PHA mitogen value minus Nil value is <0.5 IU/ml. The QuantiFERON-TB Gold Plus result is determined by subtracting the Nil value from either TB antigen (Ag) tube. For safety reasons, this is best performed by removing the syringe needle, ensuring appropriate safety procedures, removing the caps from the 4 QFT - Plus Blood Collection Tubes and adding 1 mL of blood to each (to the black mark on the side of the tube label which indicates the validated range of 0.8 - 1.2 mL).
