Comparing the benefits: Heliprobe™ is superior to other diagnostic methods for detection of Helicobacter pylori infection.
Golden Standard
Urea breath testing (UBT) is currently considered to be the golden standard for non-invasive diagnosis of Helicobacter pylori infection. It is highly reliable for pre- and post-treatment follow-up of infection. However, tests in liquid form have several disadvantages compared to HeliCap™ solid-capsule formulation.
 
To ensure equivalent results comparable with sophisticated, well-established laboratory techniques used for scientific purposes, the following comparison between Heliprobe™ and liquid scintillation for 14C detection was made. A laboratory set-up (simulating the patient) with controlled parameters according to figure 1 was established.
 
The result of the comparison was statistically analyzed applying linear regression. The outcome of the analysis shows a regression line with high correlation between these methods as presented in figure 2.
Clinical Validation studies involving more than 400 patients has also been performed at the Karolinska University Hospital in Stockholm, Sweden1.
Heliprobe™ System has been compared to other UBTs.
The conclusions from the clinical evaluations were:
The HeliCap™ capsule minimizes false positive results by eliminating urea hydrolysis in the
  mouth and on the way to the stomach.
The solid capsule eliminates the need for a pre-test meal.
Short time to sampling, only 10 minutes after capsule intake.
Results obtained on site, within 5 minutes after sampling.
Acid supplementation in the capsule reduces the risk of false negative results.
Sensitivity and specificity are 95% and 100%.
 
In conclusion, the Heliprobe™ system in comparison with liquid-based urea breath tests is more accurate, rapid and easy to use. The simplicity and handiness of the system makes it ideal for detection of Helicobacter pylori directly in the doctor’s office.
