Semiology (in a medical context) means study of signs. Sometimes also called semiotics, but it is important to note that those two words are not synonyms. Semiotics and semiology share a similar etymology and meaning. In medicine, signs are objective manifestations of disease, as opposed to the subjective nature of symptoms. Semiology comprises the study of symptoms, somatic signs and laboratory signs, history taking and physical examination (in English-speaking countries is known as Bedside diagnostic examination or Physical diagnosis).
