| positive | Having a value greater than zero, indicating existence or presence of a condition, organism, etc. As chromatin positive or Wassermann positive, characterised by affirmation or cooperation. Origin: L. Positivus (18 Nov 1997) |
| positive accommodation | The increased refractivity of the eye that occurs when shifting from the distance to a near object. (05 Mar 2000) |
| positive afterimage | An afterimage in which the lightness relationship is the same as the original one; if chromatic, it appears in the same colour. (05 Mar 2000) |
| positive afterpotential | A spontaneous or inducible increase in transmembrane potential of a cardiac or nerve cell following the completion of repolarization. In the heart, this usually corresponds to the electrocardiographic U wave. (05 Mar 2000) |
