3QBD's patented technology is based on the well established and scientifically proven Ion Mobility Spectrometry (IMS) technology, first used successfully to detect drugs and explosives. Today IMS is being used to detect the presence and type of infection. The device works by measuring elevated biogenic amines present  in infections. 

Chemical changes in living systems, or degradation of cells after death through enzymatic and microbial processes, are accompanied by the breakdown of amino-acids and production of biogenic amines. Pathological conditions in the human body may be expressed in the formation of biogenic amines, so that elevated levels of biogenic amines may be indicative of dysfunctions.

The VGTest is a patented device that uses IMS technology to diagnose the three most common forms of Vaginitis: bacterial vaginosis, candidiasis and trichomoniasis. IMS is a sensitive instrumental technique for detecting volatile compounds based on measuring the velocity of ions (ion mobility) drifting through a gas bath under the influence of an homogeneous electric field.

The initial proof of concept results with the initial VGTest device on a Ni 63 platform demonstrated diagnostic accuracy of over 95% for BV. The results for the non radioactive platform are showing similar results in the laboratory, including stronger signals. 
In addition the VGTest test spares the physician from having to perform the unpleasant Amsel Test and “whiff tests” of vaginal fluid.
