Patch Testing

Patch testing identifies specific substances responsible for allergic contact dermatitis by applying small, standardized amounts of common allergens to the skin under adhesive patches over several days. It is the gold-standard investigation for chronic or recurrent eczema believed to be triggered by contact with metals, cosmetics, fragrances or occupational chemicals. Reactions are carefully graded at two separate readings, since some allergic responses take longer to appear. The results allow targeted, practical avoidance advice rather than guesswork.

Patch Testing is recommended for patients diagnosed with specific conditions where other approaches have been insufficient. Your Dermatology specialist will assess your suitability based on your diagnosis, health history, and treatment goals.

The typical duration is 48-96 hours (readings at 48h and 72-96h). This may vary based on the complexity of your case and individual response to treatment.

Recovery typically takes No downtime is needed, though the patient must keep the back dry and avoid bathing or heavy sweating during the testing period. Once positive reactions are identified, the dermatologist provides targeted allergen-avoidance counselling and, where appropriate, adjusts skin-care products and workplace exposures.. Your care team will provide specific instructions based on your response and overall health.

Side effects vary by individual and are detailed in the section above. Your specialist will discuss all risks and benefits with you before treatment begins. Serious adverse effects are uncommon but are part of the informed consent process.

Patch Testing has a documented success rate of 90% accurate for identifying the causative allergen at accredited facilities. Outcomes depend on disease stage, patient health, and adherence to the treatment plan and aftercare instructions.
