Peptides and proteins are interchangeable terms for bio markers, the difference being that peptides are smaller. Knowledge of the potential of both peptides and protein chains for CRC diagnosis has been of interest to scientific researchers for well over 10 years. I wouldn't be surprised if Colostat includes peptides in its panel of bio markers actually, for sure they would be well aware of this science, right through the CSIRO days through to now.

There is obviously a huge global race for an improved screening test for CRC. It does not surprise me that US CLIA labs are publishing questionable advertisements that they have found the answer. One look at the graphic for 'Glycoknow', the way it's written etc. and you can tell it's utter rubbish.
