Biomarker directory — blood labs in genetic context
Plain-English guide to the blood biomarkers GENO interprets alongside your DNA. Your APOE genotype changes how your LDL should be read. Your MTHFR genotype changes how your homocysteine should be treated. Each page covers what the marker means, optimal ranges, and which genes shift the target.
Catalog (5)
ApoB — ApoB (Apolipoprotein B) — ApoB counts the number of atherogenic particles circulating in your blood — increasingly recognized as a more accurate marker of cardiovascular risk than LDL cholesterol alone.
LDL-C — LDL Cholesterol — LDL cholesterol is the most widely measured lipid risk marker — but the right target depends on your genetics, your other risk factors, and increasingly, on your ApoB.
Ferritin — Ferritin — Ferritin reflects your body's iron stores. Low ferritin is one of the most common drivers of unexplained fatigue; very high ferritin can flag inflammation or iron overload.
25(OH)D — 25-Hydroxyvitamin D — 25-hydroxyvitamin D is the best single measurement of vitamin D status — and one of the most personalized labs, because VDR and CYP2R1 genetics meaningfully change how much you need.
Homocysteine — Homocysteine — Homocysteine is an amino acid that accumulates when methylation pathways are inefficient. Elevated levels flag B-vitamin deficiency, MTHFR variants, and cardiovascular and cognitive risk.
