We apply patch tests in patients with skin rashes that are chronic and
not specific, to find out whether their skin condition may be caused or
aggravated by a contact allergen.
We often start with your own personal products as well as stock panels.
Patch tests are not the same as allergy prick skin testing which are used to
diagnose hay fever allergy (house dust mite, grass pollens and cat dander) which
measure antibody effects.
Patch testing triggers T cells, a cell in your body and skin.
Skin prick tests have very limited value for patients with skin rashes.
