Open the CIPO recordAbstract From the Canadian patent
Disclosed is an improved method for determining the concentration of a first analyte in a fluid test sample as a function of a second analyte also present in the sample whose concentration in the fluid sample is clinically related to that of the first analyte. The method involves determining the concentration of the first analyte and, if this, concentration is outside of its useful analytical range dividing, this concentration by the normal concentration of the second analyte. This method of ratioing the concentrations of the first and second analyte is advantageous because accuracy is increased with fewer false positive and false negative results being reported.

Why it's free to use
- Filed October 9, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 9, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 9, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
