A photo-acoustic sensing apparatus () for non-invasive measurement of blood parameters of a subject () comprises a photo-acoustic sensor () for sensing photo-acoustic signals () induced when a region of the subject is illuminated by a light source (). A first sensor processing module () may derive blood oxygen saturation using sensed photo-acoustic signals (). A second sensor processing module () may derive blood core temperature using sensed photo-acoustic signals. A third sensor processing module () may derive blood glucose using sensed photo-acoustic signals. The sensing apparatus is configured to derive at least one of: a de-correlated value () of blood oxygen saturation of the subject; a de-correlated value () of blood core temperature of the subject; and a de-correlated value () of blood glucose of the subject.
