Zinc
Reads: Zinc status
It is not only an enzyme cofactor — zinc fingers are among the commonest DNA-binding motifs, so zinc status reaches gene expression directly. There is NO storage pool: intake must be continuous, and high-dose zinc induces metallothionein which then traps copper, causing a secondary deficiency.
What this marker reads
Catalytic and structural cofactor for hundreds of enzymes and for zinc-finger transcription factors.
What a named body publishes
Each line below is the sentence the issuing body wrote, carried with its own identifier. Nothing here interprets your result — it states what was published, for whom, and by whom.
Serum zinc
“Morning, fasting: the suggested lower cutoff for serum zinc in males aged 10 years and over is 74 µg/dL (11.3 µmol/L), the 2.5th percentile of the NHANES II reference distribution.” males, 20+ (morning fasting rows are based on subjects aged 20 years and over)

“Morning, fasting: the suggested lower cutoff for serum zinc in non-pregnant females aged 10 years and over is 70 µg/dL (10.7 µmol/L).” females, 20+ (morning fasting rows are based on subjects aged 20 years and over)

“Morning, non-fasting: the suggested lower cutoff for children under 10 years, sexes combined, is 65 µg/dL (9.9 µmol/L); the source states 'the lower cutoffs for boys and girls aged 3 to 9 years were combined because the difference between the sexes was negligible'.” <10
