Specific IgE C312 — Lactose
The study of specific immunoglobulin E class antibodies to lactose is conducted to assess the body's allergic sensitization to milk sugar. The test is used as part of comprehensive allergological diagnostics, in chronic allergic diseases, and for monitoring allergic reactions when consuming lactose-containing products.
Test composition:
- Determination of specific IgE class immunoglobulins in blood serum
- IgE antibodies to lactose are tested
- The test aims to detect sensitization fact and degree of the body's allergic response to lactose
- The study is performed by enzyme immunoassay or immunochemiluminescence method, with high sensitivity and specificity
- The result reflects specific IgE concentration and is used for immunological assessment of the body's reaction to lactose
Clinical significance:
- Determination of specific IgE allows assessment of the allergic reaction character on contact with lactose
- The test is used for monitoring patients with chronic allergic diseases and food allergy
- Results are used for assessing risk of allergy development to dairy products
- The study complements clinical data and other laboratory test results
Biomaterial: Venous blood
- Blood is submitted fasting
- It is recommended to avoid alcohol the day before the test
- Before blood collection, it is advisable to avoid intense physical exertion and stressful situations
- The attending physician should be informed about taking hormonal medications, immunomodulators, and antihistamines.
- Food allergy symptoms after consuming dairy products
- Suspected allergic sensitization to lactose
- Prolonged or repeated contact with dairy products
- Need for dynamic monitoring of food allergies
An elevated specific IgE level indicates the presence of allergic sensitization to lactose
A low level may indicate absence of significant sensitization or formation of immunological tolerance
Final interpretation is performed by a physician considering the clinical picture and other test data
Which doctor to consult:
Allergist — for diagnosing food allergies, identifying causes of sensitization, and selecting individual treatment tactics
Immunologist — for assessing immune system status and analyzing immune response features to food allergens
General practitioner — for initial assessment of the patient's condition, prescribing examinations, and referral to specialists
