Lactose Intolerance Quick Test (25 Tests)

SKU: 602010 Category:


The BIOHIT Lactose Intolerance Quick Test was developed to support the diagnosis of lactose intolerance (hypolactasia of the small intestine) by detecting the activity of lactase enzyme in a duodenal biopsy specimen.

Used in conjunction with Gastroscopy (oesophago-gastroduodenoscopy (OGD)) a single biopsy specimen taken from the mucosa of the upper part of the small intestine is examined immediately. By the addition of three reagents the Lactose Intolerance Quick Test reveals the amount of Lactase enzyme activity in the biopsy by a colour change. The development of colour in the test liquid after 20 minutes informs the endoscopist whether or not the lactase enzyme is present in the biopsy specimen.

Each Lactose Intolerance Quick Test Kit contains:

  • Three Reagents

  • Test Plates

  • Colour chart for interpretation

  • Rapid biopsy test for Lactase deficiency (lactose intolerance)

  • 20 minute test

  • Perfomed in conjunction with gastroscopy

  • Semi-quantitative results:

    • Severe hypolactasia / alactasia

    • Mild hypolactasia

    • Normolactasia

  • Requires single D2 (post bulbar) biopsy

  • Positive control available (Product Code 602018)


  • Rapid diagnosis of a high prevalence condition

  • Provides a direct and highly specific measure of lactase activity

  • Use to report lactase expression as a functional assessment
