Subject: Does the amount of Bendedict's solution used affect the time needed?

I am currently doing an investigation into three unknown substances and 
trying to find out what is contained in each substance.  One test I used 
was the benedict's test for glucose.  Whilst trying think up variables in 
the experiment i wondered whether the amount of time needed for a colour 
change to take place while under heat is affected by the amount of 
Benedict's solution used?  If so, the amount of Benedict's used would have 
to be the same in each substance tested, and would therefore play an 
important role in the outcome of the experiment.  If you could answer this 
as soon as possible it would be a great help, thanks.
