The Power of Patient History

Your doctor's first step will be a detailed discussion about your symptoms. They'll ask about the duration, location, and nature of your itch, as well as any factors that make it better or worse. This information can provide valuable clues about potential causes.

Physical Examination

A thorough skin examination is crucial. Your doctor will look for primary skin lesions, signs of scratching, and other physical clues. They may use tools like a dermatoscope for a closer look. For some conditions, they might perform specific tests like the ice cube test for aquagenic pruritus.
Chronic pruritus is a persistent itching sensation that requires thorough diagnosis to identify underlying causes for effective treatment.

Laboratory Tests

Blood tests can help identify systemic causes of itching. Common tests include a complete blood count, liver function tests, and thyroid hormone levels. In some cases, your doctor might order more specialized tests based on their suspicions.

Advanced Diagnostics

If initial tests are inconclusive, your doctor might recommend additional procedures. These could include skin biopsies to check for skin diseases, or imaging studies to look for underlying conditions like cancer. In some cases, neurological tests might be needed to diagnose neuropathic itch.
