What does the Serum Zinc test measure?

Serum Zinc (Zn) is a clinical biomarker used in comprehensive-panels assessment. Zinc is an essential trace element required for over 300 metalloenzymes involved in neurotransmitter synthesis, synaptic plasticity, and neuronal signalling. It is measured in 1 laboratory test on BiomarkersLabs.com.

Reference Range: Approximately 60–130 µg/dL, age- and sex-adjusted.
Units: µg/dL, µmol/L
Measured In: 1 test

Functional medicine optimalFunctional practitioners may cite >80–90 µg/dL as a target for neurodevelopmental support, though these thresholds lack consensus validation.

What is Serum Zinc?

Zinc is an essential trace element required for over 300 metalloenzymes involved in neurotransmitter synthesis, synaptic plasticity, and neuronal signalling. It modulates dopamine and glutamate receptor function and is concentrated in hippocampal and cortical regions critical to attention and executive function. Serum zinc represents only a small fraction of total-body stores and fluctuates with inflammation, albumin status, and recent intake.

Why is Serum Zinc measured?

Low zinc has been associated with attention deficits, hyperactivity, and impulsivity in some observational studies, though the relationship is complex and not consistently reproduced. Zinc supplementation trials in ADHD show mixed outcomes. Serum zinc is an indirect marker of status and should be interpreted alongside clinical context and dietary history.
