Lactose intolerance is the inability of the body to break down lactose due to a low concentration, or a lack of, lactase.
Certain changes in DNA, called single nucleotide polymorphisms (SNPs) in the MCM6 (minichromosome maintenance complex component 6) gene have been associated with the most common type of lactose intolerance: physiological lactase deficiency.
MDS offer a genetic test for the more common genetic mutations associated with lactase deficiency. All that is needed is a blood sample to be sent to us for testing.
Note: The ImuPro Food Hypersensitivity test involves testing the protein components of the milk (casein and whey) and will not indicate whether you have lactose intolerance. If you have undertaken the ImuPro test and milk was found to be IgG reactive and you have the symptoms of lactose intolerance, or you would like to test for lactose intolerance, the genetic lactase deficiency test is recommended.
