H. pylori

PyloriTek® for H. pylori

Serim® PyloriTek Test Kit detects urease activity in gastric biopsy specimens providing a presumptive identification of a Helicobacter pylori infection. PyloriTek has been a standard for H. pylori testing for almost 30 years and offers several distinct advantages over other rapid urease tests (RUT) such as HP Fast, Clotest and Pronto Dry.

Advantages of Serim’s Helicobacter pylori test kit

  • PyloriTek can accommodate up to 3 large biopsies per test and provides ability to map results by location.
  • PyloriTek is the only rapid urease test containing a built-in positive control, a separate test device used for a control is not required.
  • PyloriTek yields most positive results in as little as 15 minutes; yields negative results in one hour.
  • PyloriTek has a specificity of at least 97%
  • PyloriTek is FDA registered and CLIA waived
  • Any blood on the sample will not interfere with test results.

Additional information

Investigators determined that taking 2 or 3 biopsies from several areas of the stomach can increase chances of finding infection due to the patchy distribution of H. pylori. This practice is recommended for many patients and improves test sensitivity in some patients (patients with recent or active bleeding or taking some medications). PyloriTek can test up to 3 specimens and provides a separate and distinct results for each biopsy. PyloriTek also has a built in built-in positive control to confirm the test was correctly used. Other testing options can test only one biopsy and require a separate test for a control.

Multiple studies published in major journals have shown that PyloriTek possesses specificity of over 97% and sensitivity of over 96% when compared to at least two reference methods (results from controlled studies with over 500 patients). These studies were conducted at multiple institutions comparing PyloriTek to HP Fast, Clotest and Pronto Dry and histology methods. Other products usually offer data from a single, limited study from one institution designed to optimize results. Additional research papers, including a pediatric study, are available upon request.
