Abstract
The 13C-urea breath test provides non-invasive testing for Helicobacter pylori infection with the possibility of analysis at the point of care. Point of care tests require accurate and efficient desktop instrumentation. To compare results obtained from a new infrared spectrophotometer (10 kg, 2 min sample measurement) to the previously approved UBiT-IR300 (22.5 kg, 5-6 min sample measurement). Adults underwent urea breath testing; breath samples were analyzed using the new and the predicate instruments. There were 220 adults enrolled (age range 18-74 years; M/F = 35:65); with 86 UBT positive and 134 negative cases. The overall agreement between instruments was 99.6% (95% C.I. = 97.6 to 99.9); the positive agreement was 100%. Technical performance of the new instrument was excellent.
