3270. PCR. Genetics. Lactose intolerance (13910 T>C, buccal scraping)
Description
Primary lactose intolerance is a genetic disease manifested by a deficiency in the body of an enzyme that breaks down lactose (lactase). The disease is provoked by changes in the gene that codes for the production of this enzyme in the body.
Identification of these changes allows diagnosing primary lactose intolerance and differentiating it from the secondary form of the disease, which can occur with disorders in the gastrointestinal tract.
The advantage of scraping from the inside of the cheek over other biomaterial sampling options is its non-invasiveness and painlessness.
When and who needs the test?
- symptoms of lactose intolerance (bloating, stool disorders, nausea, etc.);
- differential diagnosis of lactose intolerance and other diseases of the gastrointestinal tract in adults;
- determining the likelihood of developing osteoporosis;
- assessing the likelihood of lactose intolerance in young children to prevent bowel disorders.
Biological material
- Scrapes from various sites depending on the test
Preparing for buccal swab taking
- The biomaterial is taken under fasting conditions or 2–4 hours after eating.
- Before sampling, rinse your mouth with boiled water.
- After rinsing, it is recommended to massage the cheek to release secretions from the glands.
In the case of taking the biomaterial in the Synevo lab center, you will be offered...
