Chronic Fatigue Syndrome (CFS) is primarily diagnosed based on patient symptoms. The condition is characterized by persistent fatigue that is not alleviated by rest and is often exacerbated by physical or mental activity. To meet the criteria for diagnosis, patients typically report a range of other symptoms, including sleep disturbances, cognitive difficulties, muscle and joint pain, and post-exertional malaise, which is a worsening of symptoms following exertion.

Unlike other medical conditions that may rely heavily on laboratory tests or imaging studies for diagnosis, CFS lacks definitive tests such as blood work, X-rays, or biopsies that can confirm its presence. Instead, medical professionals utilize established diagnostic criteria, like those from the Centers for Disease Control and Prevention (CDC) or the Institute of Medicine (IOM), which place significant weight on the self-reported symptoms and the impact they have on the patient's quality of life.

This symptom-based approach emphasizes the subjective experience of the patient, along with the need to rule out other possible conditions that could explain the fatigue and associated symptoms. Therefore, the basis for diagnosing Chronic Fatigue Syndrome is firmly rooted in the symptoms reported by the patient.
