Biomarker

Could someone give me download links for biomarkers books/presentations?

Thank you

Does anyone have "Basin Analysis - by: Allen & Allen 2013" to share. I really appreciate it.
Many thanks

Can you explain me what are biomarkers?
Thanks.

Biomarker is a naturally occurring molecule, gene, or characteristic by which a particular pathological or physiological process, disease, etc. can be identified.

Dear Imran60,

And what are oil biomarkers, what are they telling us and who are the professionals which determine that?

Thanks in advance.
