How is Fever of Unknown Origin Diagnosed?
Published: Jun 28, 2024
Diagnosing fever of unknown origin (FUO) can be complex, involving multiple tests and evaluations. Let's explore the diagnostic process.
Contents
Initial Evaluations
When a patient presents with FUO, initial evaluations include a thorough medical history, physical examination, and basic lab tests. These steps aim to identify any obvious causes and rule out common conditions. Despite these efforts, many FUO cases remain undiagnosed, necessitating further investigation.
Advanced Diagnostic Techniques
When initial tests are inconclusive, more advanced diagnostics come into play. Imaging techniques like CT scans and MRI can help identify hidden infections or tumors. Specialized tests, such as tissue biopsies, may be required to confirm conditions like tuberculosis or malignancies.
Challenges in Diagnosis
Diagnosing FUO is challenging due to the nonspecific nature of fever and the wide range of potential causes. Some cases resolve without a diagnosis, while others might require repeat testing. The lack of clear symptoms in many diseases adds to the complexity.
