Zinc Deficiency Assessment

Assess zinc status using serum zinc levels and clinical indicators. Deficient: serum zinc below 70 mcg/dL (below 10.7 micromol/L). Normal: 70-120 mcg/dL. Clinical features: acrodermatitis enteropathica (perioral/perianal rash), delayed wound healing, hypogeusia/anosmia, growth retardation, immune dysfunction, hypogonadism. Serum zinc poorly reflects body zinc stores due to acute phase reaction.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Assess zinc status using serum zinc levels and clinical indicators. Deficient: serum zinc below 70 mcg/dL (below 10.7 micromol/L). Normal: 70-120 mcg/dL. Clinical features: acrodermatitis enteropathica (perioral/perianal rash), delayed wound healing, hypogeusia/anosmia, growth retardation, immune dysfunction, hypogonadism. Serum zinc poorly reflects body zinc stores due to acute phase reaction

Each component has a specific meaning:

  • Serum zinc levels — The serum zinc levels recorded for the scenario being assessed.
  • Clinical indicators — The clinical indicators recorded for the scenario being assessed.

Note: Interpret the zinc deficiency result against the thresholds and context described above.

How to Use

Enter the serum zinc levels, clinical indicators for the scenario you are assessing. Assess zinc status using serum zinc levels and clinical indicators. Deficient: serum zinc below 70 mcg/dL (below 10.7 micromol/L). Normal: 70-120 mcg/dL. Clinical features: acrodermatitis enteropathica (perioral/perianal rash), delayed wound healing, hypogeusia/anosmia, growth retardation, immune dysfunction, hypogonadism. Serum zinc poorly reflects body zinc stores due to acute phase reaction. Use the zinc deficiency result to inform your calculation.
