| Result Value | Observation of skin's reaction |
| Normal Value | Absence of abnormal skin reactions |
| Accuracy | High |
| Interpretation | Positive reaction indicates photodermatitis |
Phototesting, also known as photopatch test, evaluates the skin's reaction to ultraviolet (UV) light exposure to diagnose and differentiate photodermatitis from other forms of dermatitis.
| Skin Prick Test | Details |
|---|---|
| Also Known As | Allergy skin test |
| Purpose | Identify specific allergens of dermatitis |
| Sample | Skin pricked |
| Preparation | Discontinue antihistamines |
| Procedure | Allergens applied to skin using a tiny needle |
| Test Timing | A few minutes |
| Test Price (INR) | 1000-3000 |
| Result Value | Observation of skin's reaction |
| Normal Value | Absence of skin reactions |
| Accuracy | High |
| Interpretation | Positive reaction indicates allergen sensitivity |
Skin prick test, also known as allergy skin test, identifies specific allergens causing allergic contact dermatitis by pricking the skin with small amounts of allergens and observing the skin's reaction.
| Tzanck Smear | Details |
|---|---|
| Also Known As | Herpes smear |
| Purpose | Diagnose viral infections |
| Sample | Sample from a skin blister |
| Preparation | Clean and sterilize the blister area |
| Procedure | Scraping of the blister for sample collection |
| Test Timing | Usually takes a few minutes |
| Test Price (INR) | 1000-3000 |
| Result Value | Microscopic examination |
| Normal Value | Absence of viral characteristics |
| Accuracy | High |
| Interpretation | Findings indicate the presence of viral infections causing dermatitis |
Tzanck smear, also known as herpes smear, is a diagnostic test used to identify viral infections like herpes or varicella-zoster that can cause dermatitis.
| Test Name | Patch Testing | Skin Biopsy | Blood Tests (IgE levels) |
|---|---|---|---|
| Also Known As | Contact allergen testing | Skin tissue examination | Allergy blood test |
| Purpose | Identify allergens causing dermatitis | Determine cause of dermatitis | Measure immunoglobulin E (IgE) levels |
| Sample | Allergen patches applied on skin | Small piece of skin tissue | Blood sample |
| Preparation | Clean test area | Clean biopsy site | Fasting required |
| Procedure | Patches applied & left for 48-72 hours | Removal of a small skin tissue | Blood drawn from a vein |

| Eczema, Contact Dermatitis | Early onset in childhood, personal/family history |
| Eczema, Seborrheic Dermatitis | Well-defined plaques, silver scales, nail involvement |
| Allergic Contact Dermatitis | Non-immunologic response to irritants, no allergen involvement |
| Eczema, Psoriasis | Coin-shaped lesions, absence of flexural involvement |
| Pompholyx, Psoriasis | Vesicular eruption on palms and soles, pruritus |
Dermatitis can be differentiated from similar diseases through various factors such as pruritus, specific allergen response, and site of involvement, aiding in accurate dermatitis diagnosis and appropriate treatment.
| Specialist | Description |

| Allergist | Allergy and immunology specialist |
| Pediatric dermatologist | Children's skin disease specialist |
Dermatologists, allergists, and pediatric dermatologists are the best specialists for diagnosing and treating dermatitis.
Conclusion
Dermatitis diagnosis involves a range of tests such as patch testing, skin biopsy, blood tests, skin scraping, phototesting, skin prick test, and Tzanck smear. These tests help identify allergens, determine underlying causes, and evaluate skin reactions. Seeking proper dermatitis diagnosis is crucial for effective treatment and management of dermatitis.
Reference
Dermatitis is a common skin condition characterized by inflammation of the skin, resulting in redness, itching, and sometimes rash or blisters. It can be caused by various factors such as allergic reactions, irritants, or underlying skin conditions.
Dermatitis is diagnosed through a combination of medical history evaluation, physical examination, and various diagnostic tests. These tests may include patch testing, skin biopsy, blood tests (such as IgE levels), skin scraping, phototesting, skin prick test, and Tzanck smear. These diagnostic tools help identify allergens, determine underlying causes, and evaluate skin reactions to aid in accurate diagnosis and treatment planning.
Accurate diagnosis is crucial for effective dermatitis treatment as it helps identify the specific triggers or underlying causes of the condition. With a precise diagnosis, appropriate treatment strategies can be implemented, targeting the root cause and providing targeted relief. Misdiagnosis or inadequate diagnosis may lead to ineffective treatments, prolonging symptoms and potentially worsening the condition.
