A test to see if you are allergic to common antibiotics
1 biomarker as listed by Better2Know.
This test identifies whether you are allergic to common antibiotics, helping to prevent serious reactions
It measures both your overall allergy level (Total IgE) and specific IgE antibodies to key antibiotics
Knowing your sensitivities can guide safer prescription choices and reduce the risk of severe allergic reactions
An antibiotic allergy occurs when your immune system reacts abnormally to a drug that is normally safe for most people. Instead of tolerating the medication, your body may produce antibodies that trigger allergic symptoms.
Allergic reactions to antibiotics can range from mild to life-threatening. Symptoms typically appear shortly after taking the medicine and may include skin rashes, breathing difficulties, or digestive problems.
Immediate reactions can include hives, swelling, or anaphylaxis
Delayed reactions may cause rashes or flu-like symptoms
Being aware of your sensitivities can prevent serious complications in future treatments
Symptoms vary depending on the severity of the reaction and the individual. Mild reactions are more common, but severe reactions can be life-threatening.
Common signs of an antibiotic allergy include:
Skin rash, itching, or hives
Swelling of the lips, face, or throat
Shortness of breath, wheezing, or tight chest
Nausea, vomiting, or abdominal pain
Dizziness or fainting in more serious cases
This blood test measures your Total IgE, an indicator of overall allergic tendency, along with specific IgE antibodies to certain antibiotics. It can detect sensitisation to:
Amoxicilloyl
Ampicilloyl
Cefaclor
Penicillin G (Pen G)
Penicillin V (Pen V)
By identifying your sensitivities, your healthcare provider can recommend safer antibiotic options and help reduce the risk of allergic reactions in future treatments.
The test involves a simple blood draw performed by a trained healthcare professional. The procedure is quick and typically takes only a few minutes.
There is no special preparation required. After the analysis, you will receive a detailed report indicating your Total IgE level and any specific antibiotic sensitivities detected.
The antibiotic screen is a standard blood test and is very safe. Most people experience only minor discomfort at the needle site.
Occasionally, you may notice slight bruising or tenderness where the blood was taken. Serious complications are extremely rare. If you feel unwell after the test, seek medical advice promptly.
