Tuberculosis allergen purified dry: description, application and features
Allergen tuberculosis purified dry (ATOS) is an immunobiological drug that is used to diagnose tuberculosis. The drug contains proteins of Mycobacterium tuberculosis, which cause a reaction of the body's immune system. ATOS is produced in Russia, including the St. Petersburg Research Institute of Vaccines and Serums and an enterprise for the production of bacterial preparations.
ATOS is an injection powder that is supplied in ampoules complete with a solution for preparing the injection. Each ampoule contains 50,000 IU (international units) ATOS.
Application of ATOS
ATOC is used to diagnose tuberculosis by performing an allergy test. When the drug is introduced into the body, a reaction of the immune system occurs, which manifests itself in the form of the formation of a papule (swelling) at the injection site. The size of the papule is measured 48-72 hours after injection and is used to determine the presence or absence of tuberculosis infection.
Features of ATOS
ATOS is a purified drug, which makes it less allergenic and safer for patients. However, like any medicine, it may cause side effects such as redness, swelling and itching at the injection site.
In addition, when performing an allergy test with ATOC, it is necessary to monitor possible false-positive and false-negative results. A false positive result may occur if the patient has signs of other infections or allergic reactions. A false negative result may occur if the patient is in the early stages of infection or has a weakened immune system.
In conclusion, ATOC is an important diagnostic tool for detecting tuberculosis infection. However, before using the drug, you must consult your doctor and follow the instructions for use.
