Zinc
Test Code: ZINC
Synonyms/Keywords
Zinc in serum, Zinc in blood, Zn​
Useful For
This test is useful for monitoring zinc level in serum.  To determine deficiency or toxicity states.​
Specimen Requirements
Fasting Required Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)
Pediatric Minimum Volume
(no repeat)
No​ Serum​

Collect blood in Royal Blue Top Tube (RBTT) (this is a metal free container with no additive)​

Within 2 hours of collection, centrifuge and pour off serum into "Serum Transfer Tube" (preferred)

Please see "Collection Processing Instructions" below (including the "Important Notes")

Within 2 hours of collection, centrifuge and pour off serum into metal-free serum tube (example: "Mayo Metal Free Plastic Aliquot Vial") 2.0 mL serum​ 1.1 mL​ 1.0 mL​
Collection Processing Instructions
Sample collection instructions:
1.      Collect the sample in Royal Blue Top Tube (RBTT) (metal free)
2.      Centrifuge the sample
3.      Within 2 hours of collection: Pour off serum into "Serum 
       Transfer Tube" or metal-free aliquot tube (example: "Mayo Metal-Free Plastic Aliquot Vial") (do not use glass pipettes, etc.)
 
Important Notes / Information: Serum should be removed from the cells within 2 hours of collection. Do not use glass pipettes or aliquot tubes, rubber stoppers, wood applicator sticks (for rimming clots), etc. as these may contaminate the specimen! If absolute necessary to rim for clots, only use a plastic pipet to minimize potential sample contamination.  All collection and transfer tubes can be requested/ordered from Marshfield Labs.

Reference Range Information
Performing Location Reference Range
Marshfield​

Serum: 65-115 ug/dL

Note: Plasma levels may be 5-10 ug/dL lower than serum levels​

Interpretation
Decreased zinc levels result in decreased  taste acuity and are frequently associated with malnutrition, chronic alcoholism, leukemia, Hodgkin's disease, and diseases where gut absorption is inhibited (diarhhea, steatorrhea, celiac disease).​
