Allergy Xylocaine Fluorescence Assay Blood
What is this test?
Allergy Xylocaine test is performed to detect if the individual is allergic to the Xylocaine. This test mainly helps in measuring the IgE antibodies in the blood to assess the sensitization to xylocaine allergens. This test helps in knowing the immune response to xylocaine.
What is xylocaine?
Xylocaine is a local anesthetic drug used to numb the tissues on which it is applied. Xylocaine is also known as lidocaine or lignocaine. This is used to prevent or control pain in the procedures where the female or male urethra is involved. This is also used in the treatment of ventricular tachycardia (an abnormal rhythm of the heart) and topical treatment of urethritis (inflammation of the urethra). It is used as a lubricant for endotracheal intubation.
What is xylocaine allergy?
When the administration of xylocaine leads to some unwanted effects it may be termed as xylocaine allergy. These unwanted effects may be swelling, fainting, dizziness, difficulty in breathing, lesions on the skin, etc.
Sometimes the allergic reactions can be life-threatening causing narrowing of the airways, making it difficult to breathe. Very less often xylocaine allergy may cause an anaphylactic reaction. Anaphylaxis is a medical emergency condition which leads to facial flushing, itching, shock, sudden fall in blood pressure, constriction of airways, swollen throat, difficulty to breathe, etc.
Why this test is performed?
This test may be recommended to you before using xylocaine on any tissues to check for any allergies. If you experience any allergic reactions in the past due to any anesthetics your doctor may ask you to undergo this test.
Also known as Allergy Xylocaine Fluorescence Assay.
Test Preparation
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your Allergy Xylocaine Fluorescence Assay Blood. Your doctor will give specific instructions depending on your condition on how to prepare for Allergy Xylocaine Fluorescence Assay Blood.
No specific preparation is required for this allergy xylocaine blood test.
Understanding your test results
The normal reference range may vary depending on gender, age, health history, etc.
If your test results show high levels of IgE antibodies than the given reference range, it may indicate that the person is most likely to have an allergy.
If your test results are lower than the reference range, it may indicate that the allergy is absent in the individual.
If you get abnormal test results, consult your doctor immediately. Your doctor may recommend other tests depending on your test results.
