Abstract: A biological information measuring technique with improved reliability is proposed. A method of measuring biological information using an optical element with a totally reflecting surface, which is to be brought into contact with an object to be observed, is provided. The method includes, after the optical element has been in contact with the object to be observed, acquiring an absorbance at the totally reflecting surface in a state where the optical element is not in contact with the object to be observed, and determining by an information processing apparatus whether the object to be observed needs to be cleaned, based on the absorbance.
