What does the Total Mold Count test measure?

Total Mold Count (Total mould) is a clinical biomarker used in environmental-mould assessment. Total mould count aggregates all culturable and non-culturable fungal spores and fragments recovered from a dust sample, providing a measure of overall fungal burden. It is measured in 1 laboratory test on BiomarkersLabs.com.

Reference Range: Typically <50 spores/mg in non-problem buildings; >100 spores/mg suggests contamination.
Units: spores/mg dust

What is Total Mold Count?

Total mould count aggregates all culturable and non-culturable fungal spores and fragments recovered from a dust sample, providing a measure of overall fungal burden. It reflects the cumulative impact of outdoor infiltration, indoor amplification, and moisture-related growth.

Why is Total Mold Count measured?

An elevated total mould count indicates excessive fungal burden in the indoor environment and is used as a screening tool. It must be interpreted alongside speciation data and outdoor baselines, but consistently high counts correlate with occupant complaints of respiratory and systemic symptoms.
