182879: QuantiFERON-TB Gold Plus - LabCorp

A negative QFT-Plus result does not preclude the possibility of M. tuberculosis infection or tuberculosis disease: false negative results can be due to stage of infection, co-morbid conditions that affect immune function, incorrect handling of the blood collection tubes following venipuncture, incorrect performance of the assay, or other individual immunological variables.

Immunochromatography - an overview ScienceDirect Topics

Immunochromatography is the preserve of research laboratories as a laboratory technique. Near-patient testing, however, utilizes commercially produced ‘sticks’ which use immunochromatography. The principle is that the sample, e.g. urine, is applied to the stick which is then developed, e.g. by capillary attraction, the analyte of interest binding at a zone …
