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 I will note any initial reactions. I will see you again two days after that, where I’ll take a final “reading” of your back and any noted reactions.
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?
Investigations consist of three visits. On the first visit, I will conduct a consultation with you. Based on your history, and if we determine that an allergy could be relevant to your skin rash, I may recommend testing you to a minimum of 45 substances and sometimes upwards of 100. By your third visit, we should have an answer to whether an allergy is contributing to your skin problem.
What my patients love about my service
MY PATIENTS ARE MY BEST PROMOTERS
Please pass on my thanks to Dr Pratsou for her assessment on my continued taking of roaccutane.She was completely right, I didn’t need a new course, I needed to move away from the drug. The creams she gave me and Cetaphil recommendation have meant my skin has been the best it’s ever been (ongoing and since I saw her) ALL SUMMER :))))) I’ve had zero problems…and I’m loving it.
Thank you once again.
“Dear Dr Pratsou,
Following the consultation today I feel it appropriate to say thank you for your help in dealing with my rosacea.
On each occasion, I have visited your department I have noticed the kindness and cheeriness of all the staff I have encountered and particularly wanted to say that you made me feel at ease with your calmness and excellent manner.
All is much appreciated.”
“Thank you very much!!
You three were (and are) a great team!
I will remember you.
You made me feel comfortable.”
“Tania,
Please pass to Dr Pratsou my thanks for her skilled work.
The wound is healing beautifully and now the stitches are out it looks as though it will be almost invisible once fully healed.”
“Dear Dr Penelope, Rena & the team, (I can’t remember the nurse’s name who helped me during my 2 procedures at the Spire!)
I wanted to thank you for your support and help during a very difficult time. You guys do a wonderful job – and we are eternally grateful for your help.”
“I would like to put on record how impressed I was with the operation you performed for the removal of the SCC on my neck. I cannot even see where the cut or the stitches were! I am indeed very grateful for the excellent work you do.”
“Dear Dr Pratsou,
I am very grateful to you for your diagnosis, recommended treatment and advice. Your letter to my GP sets out both the course of events, and your own analysis of probable condition and possible cause, clearly summarising our discussion.
I hope there will be no recurrence but I will certainly come back to you if there is.”
“Dear Tania,
Please pass on my thanks to Dr Pratsou. I saw her this morning for a mole check. She was so lovely and reassuring. Please also thank the two nurses who assisted her during the mole removal procedure. I was very nervous, but they were very efficient, which meant I did not have too long to think about it, but most of all they were very kind. They kept me distracted and calm, which made a huge difference. Thank you also for your efficiency in both booking me in so quickly.”
Dear Ms. Pratsou,I am writing to thank you for the care you have given me in the past few months. From the moment I walked into your consulting room with a lesion on my cheek, a lesion that I fully expected to be some sort of skin cancer (and it was), you have been thorough, reassuring, respectful and in every way professional.
You recognised that I had some insight into the condition of my skin and the procedures required to treat me. You listened to me. You projected expertise and compassion.
During the procedure to remove the growth you ensured that the atmosphere in the treatment room remained not only calm, but actually pleasant. Had it not been that you were excising a growth and sewing me up, I almost felt as if you, me and the nurse were at some sort of women’s discussion group. The time flew by. I had zero anxieties about the procedure and as we both know now, the wound healed flawlessly.
Thank you for your expertise and your communication skills and all round good nature. I feel very lucky.

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.
