Patch testing is a specialised skin test used to determine whether you are allergic to a specific substance
FINDINGS FROM A PATCH TEST CAN HELP ME ADVISE YOU ON PARTICULAR ALLERGENS TO AVOID
What is patch testing?
Patch testing is a complex specialist investigation used to determine whether you are suffering from an allergy caused by skin contact to a specific substance. A common example is cosmetics or fragrances resulting in facial or hand eczema. Once a contact allergy which is directly relevant to your symptoms is confirmed, avoidance of the allergen can result in dramatic improvement in your skin condition.
What happens during patch testing?
Based on your history of reactions, you will be tested to a variety of possible allergens. A nurse will place a small amount of each substance in a small chamber, held in place with hypoallergenic tape, on your back. They should remain in place until you are seen two days later, when any initial reactions will be noted. You will be seen again two days after that, when a final “reading” of your back will be undertaken and any reactions will be noted.
In what circumstances is patch testing appropriate?
Patch testing may be appropriate if you have new onset eczema, persistent eczema despite appropriate treatments, or a rash that we suspect is allergic in nature.
What if patch testing is negative?
A wholly negative test is also extremely beneficial. In this case, you do not have to worry about avoiding anything specific. It can help guide how we manage your eczema.
How do you get started?
I will first conduct a consultation with you. Based on your history, and if I suspect that an allergy could be relevant to your skin rash, I may recommend a referral for patch testing. This normally consists of three visits, testing you to a minimum of 50 substances and sometimes upwards of 100. By your third visit, you should have an answer to whether an allergy is contributing to your skin problem.

About the author
Dr Penelope Pratsou | Consultant Dermatologist
MBChB, MRCP (UK) (Dermatology)
I’m Dr Penelope Pratsou, a skilled independent Consultant Dermatologist based in Berkshire. I have specialist expertise in the diagnosis and management of all skin cancers, and in performing mole checks. I’m a trained skin surgeon and remove skin cancers, moles, skin tags, cysts and warts.
I also have invaluable experience in dealing with all skin conditions, from the common skin complaints of acne, rosacea, eczema and psoriasis, to the rarer and more complex skin problems, having seen it all through years of NHS work.
After I obtained my Membership to the Royal College of Physicians, I undertook rigorous specialist training in dermatology, before being appointed as a Consultant Dermatologist at the Royal Berkshire Hospital, Reading. There, I helped set up and lead a busy clinic for the diagnosis and treatment of suspected skin cancer. I was also actively involved in supervising and training both dermatology and GP trainees.
Alongside my increasingly busy private practice, I have maintained an NHS practice in Oxford in order to continue to engage with challenging cases and to develop my specialist interest in skin allergy.
