A severe form seen in people with weakened immunity. It features thick crusts of skin filled with mites and is highly contagious.

Nodular Scabies

Some individuals develop firm, itchy nodules, especially in the groin or underarms, even after treatment, due to a strong immune reaction.

How Scabies is Diagnosed?

Diagnosing scabies begins with understanding your symptoms and checking for tell-tale signs like persistent itching and skin rashes. Since scabies can resemble other skin issues, a proper medical evaluation is crucial for accurate identification and effective treatment. Early diagnosis not only eases discomfort but also prevents it from spreading to others.

At Medicover, our dermatology team follows a patient-friendly, thorough diagnostic process that includes:

• Visual Examination: A dermatologist carefully examines affected areas for burrows, rashes, or skin lesions typically seen in scabies.
• Ink or Burrow Test: A special ink or dye may be applied to the skin to highlight mite tracks under magnification.
• Skin Scraping: A painless scraping of the skin is done to check for mites, eggs, or waste under a microscope.
• Dermatoscopy: This non-invasive imaging tool magnifies the skin, helping specialists identify mites and burrows without scraping.
• Rule-Out Testing: In cases where symptoms are unclear, tests may be done to rule out eczema, dermatitis, or fungal infections.
