How long does contrast dye allergy last?
Part of Immune system & allergy clinical trials.
This study looks at whether people who had a first allergic reaction to contrast dye (used in imaging tests like CT scans) remain sensitive to it over time. It may help doctors understand if future allergic reactions are likely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You must have a confirmed IgE-mediated (immediate) allergy to contrast dye after your first exposure to it.
- You cannot be taking antihistamines (allergy medicine) for an allergic condition at the time of evaluation.
- You cannot have active eczema or asthma that is not well controlled.
- You cannot be pregnant, breastfeeding, or have recently given birth.

This study checks whether a new blood test can measure allergy-related immune signals (IgE) in people with known or suspected allergies. If it works well, it could help doctors diagnose and track IgE allergies more easily.
This trial looks at whether doing a skin test with a full-strength (undiluted) version of contrast dye makes the test more accurate for people who have had allergic reactions to these dyes. It may help doctors figure out which contrast agent is truly causing your allergy.
This trial tests whether a 1-hour premedication plan can safely prevent allergic reactions to CT dye in adults who need an emergency scan. It may help you get faster, safer care if you have a known contrast allergy and are in a life-threatening situation.
This study looks at how contrast dye used in imaging tests (like CT scans) can sometimes affect the kidneys. Researchers want to track patients at Sohag University Hospitals to better understand and prevent kidney injury after receiving contrast.
This study is building a tool to predict which patients might have leakage of the contrast dye used in scans. It could help prevent complications during imaging procedures.
This trial tests a personalized way to calculate contrast dye for CT scans, based on your sex and body measurements. It may improve safety and image quality.
