Subjective data encompasses information that is reported by the patient, reflecting their personal experiences, feelings, thoughts, and perceptions regarding their health and well-being. This type of data is inherently qualitative, as it cannot be measured or quantified directly and relies on the patient's perspective. For example, when a patient describes their level of pain, their emotional state, or how they feel about their treatment, they provide subjective data that helps healthcare professionals understand the individual's unique situation.

While other types of data, such as objective data, might involve quantifiable and measurable elements—like laboratory results or vital signs—subjective data specifically captures the patient's own narrative. This information is crucial for tailoring treatments and interventions to better align with the patient's needs and concerns.
