suicidal rna extracter

Can anyone help us with our rna extractions?  We're using Ultraspec 
( chomsinsky's method) to extract hepatitis C rna from serum.  
When it works we get a nice product but it seems to be a bit 
of a hit and miss affair .  I think we may be missing those 
specimens with a lower target number. We often see largish pellets 
after precipitation overnight with glycogen but get no product from 
the rt-pcr. Our problem may be the quality of the water we dissolve 
the pellet in . Any ideas? many thanks.
