Persistent itching can be a puzzle to solve. Learn how doctors diagnose the underlying causes of pruritus.

Initial Evaluation Steps

When evaluating pruritus, doctors first determine if there are primary skin lesions present. This helps differentiate between dermatologic and systemic causes of itching.

Laboratory and Imaging Tests

In cases of generalized pruritus without skin lesions, blood tests and imaging studies may be needed to uncover systemic diseases. These tests help rule out conditions like liver disease or thyroid disorders.

Persistent itching, or pruritus, can be caused by dermatologic or systemic conditions. Diagnosis involves evaluating skin lesions and conducting laboratory and imaging tests.

Skin Biopsy and Other Tests

For certain skin conditions, a skin biopsy might be necessary to identify the specific disorder. Additionally, tests for skin infections or allergies may be conducted based on the patient's history.
