摘要
Although blood is the most common source for biomarkers,urine has not been completely ignored. There have been some urinary biomarker studies with clinical samples.However, most-if not all-biomarker researchers lack confidence in urine as a good biomarker source. Many researchers think that good results from urine are a statistical accident. To demonstrate the validity of urinary biomarkers,large-scale studies are needed. Until such convincing evidence exists, what funding agent could support research in this field?
