  • Certain ethnic groups. In the Russian population, lactase deficiency is observed in about 16 %.

  • Infants (the development of lactose intolerance is associated with adulthood).

How to diagnose lactase deficiency?

  • Rapid test for the diagnosis of the activity of the enzyme lactase in order to determine the degree of lactase deficiency (duodenal biopsy)
