This information is intended solely for healthcare professionals.
The urea breath test should be performed in the presence of qualified medical personnel, preferably under the supervision of a doctor. Depending on the analytical method used for the determination, a suitable container for the breath samples (tube or bag) should be selected.
The analytical method will also determine the number of samples to be taken at each sampling time and the volume of sample required for the determination.
The patient should attend the doctor's visit in the morning. The urea breath test should be performed with the patient fasting (both liquids and solids) for at least 8 hours, preferably overnight. The patient should rest for 10 minutes before the test.
The patient should be seated while the test is performed.
1.The test procedure begins with the labeling of the sample containers and the collection of the basal sample.
2.The patient will exhale gently but continuously into the sample container, which will be closed immediately afterwards. In the case of breath samples being analyzed using infrared spectrophotometry, it is recommended that the patient hold their breath for a few seconds in the moments immediately before sample collection.
3.Immediately afterwards, the patient will swallow a whole UBTest 100 mg tablet without crushing or chewing it with 100 ml of water.
4.The person performing the urea breath test should record the time of ingestion.
5.The patient will change position to left lateral decubitus for 5 minutes and then remain seated, upright and calm, until the second sample collection.
6.Twenty minutes after ingestion of the coated tablet, the second breath sample will be collected in the corresponding container, properly labeled, as described in point 2.
The enrichment of 13C in exhaled air is expressed as an absolute difference (value Δ13CO2 [‰]) between the ratio 13C/12C before administration of the tablet (basal value) and 20 minutes after its administration. If the Δ13CO2 value is equal to or greater than 2.5‰, the patient is considered infected with H. pylori.
Two methods have been validated (infrared spectrophotometry (EIR) and gas chromatography in-line with mass spectrometry of isotope ratios (CG/EMIR)) in clinical studies to analyze the urea breath test.
In a phase III clinical trial with UBTest 100 mg coated tablets, the urea breath test was performed on 130 patients infected with H. pylori and 124 patients not infected with H. pylori. The analysis by mass spectrometry of the breath samples taken 20 minutes after administration of the tablet resulted in a diagnostic sensitivity of 97.7% [95% CI: 93.4 to 99.5%], a specificity of 98.4% [95% CI: 94.3 to 99.8%] and an accuracy of 98.0% [95% CI: 95.5 to 99.4%] with a cutoff point for Δ13C of 2.5‰.
It must be ensured that the CO2 concentration and the ratio 13C/12C do not vary from the moment of exhalation to the analysis of the breath samples. This occurs when using containers with humidity extractors. Such containers should be avoided.
Range of CO2 concentration: 1% - 6%
Linearity:y = 1.01x - 0.20; r2 = 1.000
Sensitivity:0.5 ‰ (detection limit of Δ13C)
Reproducibility:DE: ± 0.5 ‰ or less than a CO2 concentration of 3% in the exhaled air
Accuracy:Error of measurement: ± 0.5‰ or less (in Δ13C: 0 - 50‰)Error of measurement: ± 1‰ or less (in Δ13C: 100‰)
B)Validation of gas chromatography in-line with mass spectrometry of isotope ratios
Range of CO2 concentration: 1% - 5% (for a breath sample volume of 10 ml)
Linearity:y = 1.0183x + 0.5686; r2 = 1.000
Sensitivity:0.2 ‰ (detection limit of Δ13C)
Reproducibility:DE (δ13C): ± 0.2‰ or less than a CO2 concentration of 3% in the exhaled air
Accuracy:DE (δ13C, n = 5): ± 0.3‰ or less than a CO2 concentration between 1% and 5% in the exhaled air
The reference gas must be normalized against an appropriate international reference standard to allow comparison of results between laboratories.
Explanation of results:
δ13C: difference in parts per thousand (‰) relative to an accepted international standard. Δ13C, Δ13CO2:difference between the determinations of the samples taken before and after administration of urea (13C). The patient is diagnosed as not infected if the value of Δ13CO2 is less than 2.5‰.
The average price of Ubtest 100 mg comprimidos recubiertos con pelÍcula in July, 2025 is around 30.46 EUR. Prices may vary depending on the region, pharmacy, and whether a prescription is required. Always check with a local pharmacy or online source for the most accurate information.
