November 2009

Following a successful run, the results of QuantiFERON In-Tube are reported out as positive, negative, or indeterminate. An indeterminate result implies that the level of interferon gamma detected by the ELISA was between the cutoff for positive and negative. An indeterminate result may be due to several factors. First, it may be due to a low mitogen (or positive control) response. This can occur in immunocompromised patients, or from improper mixing of the collection tubes. The second scenario which may result in an indeterminate is a high nil (or negative control) value. This may result from improper collection, incubation, transport or processing of the collection tubes.
