Appendix B – Mathematical Techniques 

This appendix describes the mathematical techniques used in more detail. 

15.1

 

Quantitation 

Calculated concentrations are obtained from a simple linear regression model, with the known 
values the log concentrations (x) and the experimental values the CT values (y). 

The log concentrations and CT values of the standards are used to construct a model in the form: 

y = Mx + B 

15.1.1

 

Confidence intervals for calculated concentrations 

We use the following confidence interval 100(1- 

α

)% for an estimate of a new observation x0 from 

the standard curve. 

 

This is the confidence interval for the concentration of a single unknown. 

Suppose now we have k further observations at x = x0 and we denote their average by 

. Then, 

 

and arguments similar to above give 

 

This formula determines how confidence intervals for concentrations of replicate unknowns are 
determined.
