Description
Basophil Activation Test (BAT) is a modern laboratory method that helps determine whether you have an allergy to injectable medications (such as anesthetics, non-steroidal anti-inflammatory drugs, analgesics, antibiotics, serums, etc.). It also allows for the assessment of the risk of severe allergic reactions (such as angioedema or anaphylaxis) before the drug is administered, meaning you can find out in advance how safe a medication is for you. Unlike provocation tests, BAT does not require the drug to be introduced into the body, so it cannot trigger an allergic reaction. A key advantage of the test is that it can detect both obvious and hidden allergic responses and comprehensively assess individual sensitivity to all components of the drug.
To undergo the test, you must bring the specific medication you wish to test (in injectable liquid form) to the laboratory and provide a venous blood sample.
Important Information!
The test can be taken Monday through Friday according to the blood
collection schedule of the selected laboratory department.
for the medication:
- The medication must be in the form of an injectable solution (factory packaging – ampoule, vial, prefilled syringe, or cartridge for automatic injection);
- Sterile (undamaged) packaging;
- Clearly labeled with the name of the medication.
These requirements ensure the proper conduct of the test and the reliability of the results.
When and who needs the test?
Basophil Activation Test is especially important for groups at higher risk of developing drug allergies: those with multiple allergies, chronic diseases and/or immunodeficiency conditions, a history of anaphylactic reactions, and cases where other tests do not provide accurate results.
It is used for:
- Diagnosing drug allergies to injectable medications (antibiotics, anesthetics, non-steroidal anti-inflammatory drugs, analgesics, vitamins, serums, radiocontrast agents, etc.);
- Assessing the risk of anaphylactic reactions (Quincke's edema, hives, anaphylactic shock);
- Individually selecting medications to prevent the risk of drug allergies before starting treatment.
The test results can be influenced by medication intake, acute inflammatory processes, stress, physical exertion, and violations of preparation rules before blood collection.
Biological material
- Venous blood
Preparing
To eliminate factors that may affect test results, we recommend following these preparation guidelines:
- fasting blood sample collection is an important requirement for laboratory testing;
- for 6 to 12 hours before the test, you should refrain from eating, drinking alcohol, smoking, and limit physical activity....
