Abstract
A method and device are provided for measuring a level of a clinically relevant analyte (such as glucose) in a fluid (such as blood). The device includes a flow path for conducting said fluid through the device; a detection chamber arranged on said flow path; and detector means arranged to detect analyte levels in the fluid in said chamber, wherein: said detection chamber contains a predetermined amount of an analyte such that that analyte mixes with fluid in the detection chamber to form, at the detector means, a calibration sample of the fluid at a time after the arrival of the fluid in said detection chamber, and said detector means is arranged to detect a first analyte level of an unadulterated sample of the fluid at a first time which is before the formation of said calibration sample and to detect a second analyte level of said calibration sample at a second time which is after the formation of said calibration sample.

67. A method for testing, in a portable device, a level of a clinically relevant analyte in a fluid, the method including the steps of:
-
guiding a sample of the fluid to a detection chamber containing a known amount of an analyte; measuring an analyte level in an unadulterated sample of the fluid at a first predetermined time after the arrival of the fluid in said detection chamber; measuring an analyte level in a calibration sample of the fluid which has mixed with said known amount of said analyte at a second predetermined time after the arrival of the fluid in said detection chamber, being later than said first predetermined time; and adjusting the analyte level measured in said unadulterated sample using the analyte level measured in said calibration sample. - View Dependent Claims (68, 69, 70)
