Zinc Quantitative, Whole Blood
2009373
Ordering Recommendation
Limited utility as an indicator of deficiency; concentration does not correlate well with intake. Serum or plasma concentrations (0020097) are best for assessment of deficiency over short periods of time. For acute toxicity, urine concentration (0020462) may be a more reliable indicator of exposure.
