Detection of Lactose Intolerance from a Biopsy Sample*

Lactose intolerance (hypolactasia) results in inability to digest lactose, the predominant sugar of milk. This inability results from a shortage of the lactase enzyme, which is produced in the small intestine. Lactase breaks down milk sugar (lactose) into simpler forms (glucose and galactose), which can then be absorbed into the bloodstream.

Lactose intolerance may cause following gastrointestinal symptoms after the intake of lactose:

Nausea
Flatulence
Abdominal bloating, cramps, pain
Diarrhea

The patients seeking medical treatment for the symptoms

caused by lactose intolerance are often ordered to an upper

intestinal endoscopy. Biohit’s unique Point of Care (POC) -test in connection with gastroscopy enables a quick diagnosis of the patients suffering from lactose intolerance. The test is a simple procedure with ready for use reagents, requires no special equipment and enables easy visual interpretation.

Detection of Helicobacter pylori Urease Activity in Biopsy Specimens*

Helicobacter pylori infection is the most important cause of chronic gastritis. H. pylori is a spiral shaped, gram-negative bacterium that colonizes the human stomach. The organism is found in the mucous layer of the stomach overlying the gastric epithelium, and the mucosa underneath the area of the H. pylori colonization is invariably inflamed. This condition is referred to as a chronic superficial or non-atrophic gastritis, which, if untreated persists for life. The chronic inflammatory process can lead to atrophic gastritis, which has been linked with peptic ulceration and gastric cancer.

The epidemiological evidence of a link between H. pylori infection and gastric adenocarcioma or mucosa associated lymphoid tissue (MALT) lymphoma and has resulted in the classification of the organism as a group I carcinogen.

Biohit’s Point of Care (POC) Helicobacter pylori Quick Test for

detecting Helicobacter pylori infection in the stomach is based on the activity of urease enzyme in a biopsy specimen. The biopsy specimen taken from the stomach is examined immediately. The development of the color in the test gel after 1-2 minutes informs whether urease enzyme is present in the biopsy sample or not. H. pylori contains large amount of urease, which degrades urea to ammonia (NH₄⁺). The formed ammonia is detected by an indicator color present in the gel.

Detection of Fecal Occult Blood with ColonView Hb and Hb/Hp tests*

ColonView lateral flow tests are intended for simple detection of fecal occult blood (FOB) in stool samples. The diagnosis of blood is based on sensitive and specific immunochemical detection of human hemoglobin or hemoglobin/haptoglobin complex. The principal use of the Biohit ColonView Hb and Hb/Hp tests is to screen for lower gastrointestinal (GI) pathologies, such as colorectal cancers and large adenomas that bleed.

ColonView Hb and Hb/Hp tests are provided with easy-to-use patient Sample Collection Kits that include all that is needed for convenient home sample collection, without the need to touch fecal samples. The same sample can be used for both Hb and Hb/Hp testing.

ColonView Hb and Hb/Hp tests are simple, one-step lateral flow tests that give a result in 15 to 25 minutes.
