IDkit HP One
Name: IDkit HP One
Warnings and Precautions
- For in vitro diagnostic use only. The 13C-urea tablet and Citrica Powder are dissolved in a glass of water and the resulting solution is taken orally as part of the diagnostic procedure.
- Phenylketonurics: Contains Phenylalanine, 84 mg per dosage unit of Citrica Powder.
- In the case of accidental overdose – drink water and call the physician.
- A negative result does not rule out the possibility of H. pylori infection. False negative results can occur with this procedure. If clinical signs suggest H. pylori infection, retest with a new sample or an alternate method.
- A false positive test may (rarely) occur due to urease associated with other gastric spiral organisms observed in humans such as Helicobacter heilmanni.
- A false positive test could occur in patients who have achlorhydria.
- Antimicrobials, proton pump inhibitors, and bismuth preparations are known to suppress H. pylori. Ingesting these medications within two weeks prior to performing the breath test may produce false negative test results.
- Tiny particles may remain visible in the reconstituted 13C-urea and Citrica solution after thorough mixing for up to five minutes. However, if more substantial particulate matter is still present after five minutes of mixing, the solution should not be used, and a new kit should be opened.
Shelf life and storage
Store at 25°C (77°F); excursions permitted to 15-30°C (59-86°F) [see USP Controlled Room Temperature]. The following components of the test kits have expiration dates: the 13C-urea tablet and the Citrica Powder. Do not use either of these components beyond the expiration date stated on the respective labels.
Calibration
The calibration stability of the BreathID® system is ensured by the Exalenz proprietary 12CO2 and 13CO2 Isotope Specific InfraRed (ISIR) lamps. The physical process underlying gas discharge emissions supports this stability. The emissions are caused by molecular rotation-vibration transitions, each generating a spectral line at a specific wavelength, uniquely defined to an accuracy of better than 0.01 Å (Angstrom). Five gas samples of known concentration and isotope ratio are used to adjust the absorption cell calibration curves, aiming to attain identical isotope ratios over the collection range of CO2 concentrations. This will ensure accurate readings in both negative and positive samples.In addition, quality checks as described above in the Quality Control section are performed by the BreathID® device after every 25 tests in order to ensure that the BreathID® System performs within established limits, and calibration is performed if required. Refer to the BreathID® Operator’s Manual for a complete description of the SystemCheck and calibration procedure.
Limitations of the test
- Post treatment monitoring of H. pylori should be performed after at least four weeks of treatment for H. pylori infection. Earlier assessment may give false results.
- Safety and effectiveness in patients under the age of 18 years have not yet been established.
- Data is insufficient for recommending the use of this test on patients with total or partial gastrectomy.
- Data is insufficient to recommend the use of this test on pregnant and lactating women.
- A correlation between the number of H. pylori organisms in the stomach and the BreathID® results has not been established.
Expected values
Delta Over Baseline values for the BreathID® test were determined in a controlled clinical study of 186 adult asymptomatic and symptomatic patients (101 infected and 85 uninfected) in Israel, using a known reference standard called the Isotope Ratio Mass Spectrometer (IRMS) and performed in a local Israeli laboratory. The range of Delta Over Baseline values for the uninfected patients was determined to be between 1 and 8. A histogram of the distribution of Delta Over Baseline values from uninfected patients is shown in Figure 5 below.
Delta Over Baseline values, as determined by the BreathID® in a pivotal clinical study, were used to confirm the initial clinical data. In the pre-therapy phase, there were 47 infected and 253 uninfected patients. Congruent results obtained by rapid urease test and histological examinations of biopsy tissue were used as the reference standard and were confirmed by the BreathID® in the 47 infected patients. In the post therapy phase, 22 patients were infected and 50 were uninfected. The reference standard in this phase was at least one positive finding from either an endoscopic test (rapid urease or histology) or by the Meretek UBT®.
The following values were obtained for the data from the pivotal study:
Upper 97.5% percentile of the Negative patients: 2.245
Lower 2.5% percentile of the Positive patients: 7.212
A histogram of the distribution of Delta Over Baseline values from pre-therapy uninfected (first phase) patients is shown in Figure 6 below.
