Allergy Metronidazole Enzyme Assay Blood
What is this test?
Allergy Metronidazole blood test is used to detect any allergies caused by metronidazole. This test mainly helps in measuring IgE antibodies in the blood to assess the sensitization to metronidazole allergens. This test helps in knowing the immune response to metronidazole.
What are metronidazole and metronidazole allergy?
Metronidazole is an antibiotic which is used to treat a variety of infections. Metronidazole belongs to a class known as Nitroimidazoles. It acts by stopping the growth of bacteria and protozoa. This medication can be used in combination with anti-ulcer medications which treats ulcers. Metronidazole allergy may happen when the immune system mistakes the contents in the metronidazole for a foreign substance. Then the body produces a reaction similar to the one created during an attack of bacteria or virus. The symptoms of metronidazole allergy are swelling of the face, lips, tongue, skin rashes, itching, hives, redness, stomach cramps, abdominal discomfort, nausea, vomiting, diarrhea, tightening of the chest, throat, etc.
Sometimes the allergic reactions can be life-threatening causing narrowing of the airways, making it difficult to breathe. Very less often metronidazole 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 in breathing, etc.
Why this test is recommended?
This test may be recommended to you if you experience symptoms like swelling of the face, lips, tongue, skin rashes, itching, hives, redness, stomach cramps, abdominal discomfort, nausea, vomiting, diarrhea, tightening in the throat, etc immediately after receiving metronidazole. This test may be recommended to monitor the effectiveness of the treatment given for the metronidazole allergy.

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.
