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.

Stability

Ambient 22 days
Refrigerated 14 months
Frozen 14 months

Rejection Criteria

Hemolysis Visible
