Search the Biomarker Database
Search all conditions at once — filter by condition, biomarker name, LOINC, or clinical trial outcome (NCT ID).
Condition Atlases
Select a condition to explore its biomarker database, category deep-dives, and key references.
Long COVID Biomarker Atlas
Cytokines, metabolomics, coagulation, vascular, neurological, proteomic, lipidomic, and microbiome alterations vs healthy and recovered individuals.
PACVS Biomarker Atlas
Spike antigen persistence, serologic discrimination, GPCR autoantibodies, mitochondrial dysfunction, and shared spike-protein pathology markers.
ME/CFS Biomarker Atlas
Cytokine meta-analyses, acylcarnitines, mitochondrial dysfunction, NK cell impairment, HRV, GPCR autoantibodies, and urinary metabolomics.
Lyme Disease Biomarker Atlas
Two-tier serology, C6 peptide ELISA, CSF neuroborreliosis markers (CXCL13), co-infection panels, and chronic/post-treatment Lyme research markers.
Gulf War Illness Biomarker Atlas
Chronic inflammation (CRP, TNF-α, IL-6), homocysteine, IFN-γ, cholinergic autoantibodies, pesticide exposure markers, ocular biomarkers, and autonomic dysfunction.
Cross-Condition Biomarker Overlap
These conditions share clinical phenotypes and convergent biomarker domains. Entries marked "overlap" in individual atlases indicate shared literature findings.
Autonomic / HRV
Reduced heart rate variability and orthostatic intolerance appear across ME/CFS, Long COVID, PACVS, Lyme (PTLDS), and GWI.
Mitochondrial / Metabolic
Acylcarnitines, lactate, ATP deficit, and amino acid depletion (serine, sarcosine) are reported in ME/CFS, Long COVID, and GWI cohorts.
GPCR Autoantibodies
β-adrenergic and muscarinic receptor autoantibodies link dysautonomia phenotypes in ME/CFS, Long COVID, PACVS, and GWI research.
