EFFECTIVE 12/12/18 - Quantiferon in-tube test change. The 3-tube Quantiferon collection set has been phased out by the manufacturer and testing using the 3-tube set will no longer be offered after 12/13/18. The new Quantiferon assay only requires a single tube and will provide a superior test offering more flexibility in collection time. Please continue to request Quantiferon tubes from the Pathology Lab and be aware that you will be supplied with the one-tube collection kit. Any patients collected in 3-tube sets after 12/13/18 will have testing canceled and a new order placed with collection in the one tube kit.
