Biomarker Reference · Cat:DA
Catecholamine to Dopamine Ratio (Cat:DA) is a clinical biomarker used in neurological-mental-health assessment. This derived marker expresses the relative balance between downstream catecholamines (norepinephrine and epinephrine) and their precursor dopamine. It is measured in 1 laboratory test on BiomarkersLabs.com.
This derived marker expresses the relative balance between downstream catecholamines (norepinephrine and epinephrine) and their precursor dopamine. It is intended to reflect the efficiency of catecholamine synthesis and the balance between dopaminergic reward-drive and adrenergic stress response.
A high ratio suggests preferential conversion of dopamine to norepinephrine and epinephrine, interpreted as a stress-dominant or hyperadrenergic state. A low ratio may indicate dopamine accumulation or impaired hydroxylation, hypothesised to correlate with low motivation or 'dopamine-dominant' patterns. These interpretations are framework-specific and not validated outside functional-medicine practice.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
