First, look up similar studies in PubMed and try to determine what normal levels are. We have optimized recommended dilutions for most validated sample types to minimize any sample interference in the result. If you are running a sample type we do not list, please contact us first to see if we have any data on that type. If we do not, you may have to run linearity and spiked sample dilution experiments to determine what dilution will give you linear results.
