The first signal is used to obtain a nephelometric measurement and the second signal is used to obtain a spectrophotometric measurement of the sample. The methods and apparatus are useful in in-vitro diagnosis.

Why it's free to use
- Filed October 10, 2000 and granted April 5, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 10, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 10, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
