Ask AI: what is the problem with biomarkers now days

The main issue with biomarkers today is that there is still a lack of understanding and agreement on what constitutes a valid biomarker and what method should be used to analyze it. Additionally, there is a lack of standardization in how biomarkers are measured and evaluated, which makes it difficult for researchers to draw meaningful and consistent conclusions from studies. Finally, because biomarkers are often difficult and costly to measure, researchers may not have access to the necessary resources or expertise to accurately measure and interpret biomarkers.
