Zinc, Urine

Diagnostic Use

Zinc is an essential trace element, needed for normal growth and development, wound healing and immuno competence. It is associated with metaloenzymes.

Zinc is mainly excreted in the faeces with small amounts being lost via the kidneys: urinary zinc increases in nephrosis, post alcoholic hepatic cirrhosis and hepatic porphyria. Increased excretion also occurs in total starvation and on administration of chelation agents

Reference Intervals

Biological Reference ranges:

Urine Zinc                        2.3 – 19 umol/24hr

Random ref range          0.4 – 17.4 umol/L

Zinc/Creatinine ratio     0.1 – 1.4 umol/mmol

To convert urine zinc umol/L to ug/L multiply by 65.

For example 10 umol/L = 650 ug/L (1 ppb)
