How to detect/diagnose/test Contact Dermatitis?
Contact dermatitis is a kind of skin inflammation that occurs when substances touching your skin cause irritation or an allergic reaction. The resulting red, itchy rash isn't contagious or life-threatening, but it can be very uncomfortable.
Contact dermatitis usually occurs in areas of your body that have been directly exposed to an offending substance — for example, under a watchband that triggers an allergy. But some reactions don't correlate exactly with areas of direct contact. For example, you may apply a lotion over your whole face, but only some areas may react.
A thorough medical history and physical exam. Your doctor will talk to you about your signs and symptoms, questioning you to uncover clues about the culprit, and examining your skin to note the pattern and intensity of your reaction.
A patch test (contact delayed hypersensitivity allergy test). During a patch test, small quantities of potential allergens are applied to adhesive patches, which are then placed on your skin. The patches remain on your skin for two days before your doctor evaluates your response. If you're allergic to a particular substance, you develop a raised bump or a reaction limited to the skin just beneath the patch.

Skin disorders comprise about 35% of occupational diseases, and the majority of these (more than 95%) are types of contact dermatitis.
Irritant contact dermatitis is the most common type. This reaction occurs when a substance damages your skin's outer protective layer.
Allergic contact dermatitis occurs when a substance to which you're sensitive (allergen) triggers an immune reaction in your skin.
Neurodermatitis - this skin condition is characterized by chronic itching and scaling. This cycle of chronic itching and scratching can cause the affected skin to become discolored, thick and leathery.
Bacterial or fungal skin infection. Severe itching and prolonged scratching may encourage moistness and oozing, creating a hospitable environment for bacteria or fungi.
