Biological marker2
However, given that ADEM lacks a specific identified biological marker rendering a reliable laboratory diagnosis, long-term follow-up is important as there are instances where an illness initially diagnosed as ADEM is ultimately replaced with a diagnosis of MS. (medscape.com)
A biomarker (biological marker) is a marker (not necessarily a quantifiable laboratory parameter) defined by the Food and Drug Administration (FDA) as "A defined characteristic that is measured as an indicator of normal biological processes, pathogenic processes, or responses to an exposure or intervention, including therapeutics interventions.

CONCLUSION: These findings provide information that need to be respected in pre-analytical standard operating procedures for clinical and research practice to generate most reliable plasma Aβ measurements. (researchsquare.com)
Diagnosis2
We found that the targeted CSF panel of 48 proteins (CSF 48 panel) performed at least as well as existing AD CSF biomarkers (Aß42, tTau, and pTau181) for predicting clinical diagnosis, FDG PET, hippocampal volume, and measures of cognitive and dementia severity. (bvsalud.org)
In conclusion, we show that the CSF 48 panel complements existing AD CSF biomarkers to improve diagnosis and predict future cognitive decline and dementia severity. (bvsalud.org)
