Zinc, Plasma

Test Overview

Method

High resolution sector field inductively coupled plasma-mass spectrometry (HR-SF-ICP-MS)

Result Included

Zinc (µg/L); Zinc (µmol/L)

Specimen

Specimen Type

Avoid gel separator tubes
Plasma (K2-EDTA)

Containers

Preferred Containers

BD 6 ml K2-EDTA Royal Blue Vacutainer (Reference # 368381)

Volume

Sample Volume

3.0 mL

Minimum Volume

1.0 mL

Specimen Comment

Avoid gel separator tubes.

Collection & Handling

Collection Instructions

Collect in contaminant-free tube. Avoid hemolysis.

Handling Information

Separate as soon as possible and transfer plasma to polypropylene vial. Store and send cold.

Additional Information

Concentrations of zinc are much higher in erythrocytes than in plasma. The results in plasma may be falsely elevated if not separated within 30 minutes and/or hemolysis is present. Serum concentrations are higher due to release from platelets during coagulation.
