this known 13 The disadvantages of C UBT are: a) the high cost of the device (Otsuka America POCone infrared spectrometer at $25,000), and the need for professional operation for a fee; b) 13 C-labeled urea is costly; c) the cost of a breath test kit is relatively high ($110); d) its availability is very limited at the point of care and directly to consumers as an over-the-counter product

Disadvantages of invasive and non-invasive diagnostic methods greatly limit H. pylori detection and subsequent eradication worldwide
