Allergy Paracetamol Enzyme Assay Blood
What is this test?
Allergy paracetamol blood test is used to detect any allergies caused by paracetamol. This test mainly helps in measuring the IgE antibodies in the blood to assess the sensitization to paracetamol allergens. This test helps in knowing the immune response to paracetamol.
What is paracetamol allergy?
Paracetamol is also known as acetaminophen. It belongs to the class Non-steroidal anti-inflammatory drugs (NSAIDs). It is used as a pain killer to relieve mild to moderate pain, such as headache, body pains, muscle cramps, sprains, toothache, etc. It is available as tablets, capsules, liquids, soluble tablets, injections, suppositories, etc. Paracetamol is usually combined with other ingredients. This may be available in various brands and names. Paracetamol allergy may happen when the immune system mistakes the contents in the paracetamol 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 paracetamol 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 paracetamol 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 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 paracetamol. This test may be recommended to monitor the effectiveness of the treatment given for the paracetamol allergy.
