noun
objective symptoms; signs
Medical term for symptoms that can be observed by a doctor, as opposed to subjective symptoms reported by the patient. Often contrasted with 自覚症 (subjective symptoms).
医師は他覚症として発熱と発疹を確認した。
The doctor confirmed fever and rash as objective symptoms.
他覚症と自覚症を区別して診断する。
Diagnose by distinguishing between objective and subjective symptoms.
Compound of 他 (other) + 覚 (perceive) + 症 (symptom), literally 'symptom perceived by another'. The exact historical derivation is uncertain, but the term follows standard medical kanji usage.
