The present invention provides a method of using a reflectance-reading device to determine an initiation time point for measuring the chemical reaction of an analyte from a biological liquid sample on a test surface. The initiation time point is determined by using a device to read a reflectance of a...http://www.google.es/patents/US5885839?utm_source=gb-gplus-sharePatente US5885839 - Methods of determining initiation and variable end points for measuring a chemical reaction
