METHOD FOR UREA BREATH TEST USING LIQUID SCINTILLATION COUNTER

摘要

The present invention comprises the steps of (a) capturing the radiocarbon contained in the CO ₂ discharged to aerobic after oral administration of a compound labeled with a radioisotope C-14 to the subject; (b) aerobic testing of the radioisotope C-14 labeling compound, comprising mixing the collected radiocarbon with a scintillator and analyzing the signal with a liquid scintillation counter.;The collection tube of the present invention for implementing the urea breath test method is a tube (1) made of a material such as polyethylene; A net (2) on the side and bottom surfaces of the tube so as to be well mixed with the Scintillation Cocktail solution, which is a substance in the tube during the radioactivity detection process; Crystals or powders (3) such as calcium hydroxide filled with a radiocarbon absorbent inside the collecting tube; If the state of the radiocarbon absorbent in the liquid phase in the collecting process, and the like instead of the collecting tube (1) is composed of a collection sample bottle (9) containing a liquid radiocarbon absorber.
