Possible Deficiency
- Poor wound healing
- Reduced taste or smell
- Hair loss or skin changes
- Frequent infections
- Reduced appetite
Plasma Zinc Test
$59.00
Order a plasma zinc blood test through LabCorp to evaluate possible zinc deficiency. Zinc is essential for immune defense, wound healing, skin health, taste and smell, reproductive function, brain signaling and copper regulation.
Consider testing when there is poor wound healing, frequent infections, hair loss, skin irritation, reduced taste or smell, fatigue, brain fog, anxiety or suspected copper imbalance.
For a broader Walsh evaluation, zinc may be tested with serum copper and ceruloplasmin.

Description
Zinc Deficiency Test, Plasma
Order a plasma zinc test online through LabCorp. This blood test measures circulating zinc and can help evaluate suspected zinc deficiency when diet, gastrointestinal problems, chronic illness, poor wound healing, reduced taste or smell, hair loss, frequent infections or other clinical concerns are present.

What Does a Plasma Zinc Test Measure?
The test measures zinc circulating in plasma. Zinc is required for immune defense, tissue repair, taste and smell, reproductive health, protein synthesis, antioxidant activity and many zinc-dependent enzymes.
Plasma zinc is the most practical starting test for suspected deficiency, but it represents only a small portion of total body zinc. Results can be influenced by inflammation, infection, fasting status, time of day, albumin concentration and recent zinc supplementation.
Who May Benefit From a Zinc Deficiency Blood Test?
Higher-Risk Conditions
- Chronic diarrhea
- Celiac or inflammatory bowel disease
- Bariatric surgery
- Restricted or low-protein diets
- Alcohol-related or chronic illness
Walsh and Copper Evaluation
- Copper overload concerns
- Pyroluria assessment
- Anxiety or mood symptoms with suspected mineral imbalance
- Monitoring zinc treatment
- Broader biotype testing
Should Copper and Ceruloplasmin Also Be Tested?
Zinc and copper interact during absorption and biochemical regulation. Low zinc may contribute to poor copper control, while prolonged high-dose zinc can suppress copper absorption and eventually cause copper deficiency.
Copper and ceruloplasmin are especially useful when there is anxiety, panic, irritability, hormonal sensitivity, postpartum mood change, pyroluria, unexplained anemia, neuropathy or prolonged zinc use.
For a fuller copper assessment: the Copper, Zinc and Ceruloplasmin Panel is usually more informative than plasma zinc alone because it helps evaluate total copper, zinc status, copper transport and estimated free-copper patterns.
How to Prepare for the Zinc Blood Test
- Follow the collection and fasting instructions included with the order.
- Report zinc supplements, multivitamins and mineral products.
- Do not stop prescribed medications unless directed by the prescribing clinician.
- Recent supplementation or acute illness may affect interpretation.
- Complete testing at the laboratory listed in the order instructions.
How Are Zinc Test Results Interpreted?
A result should be interpreted with the clinical history rather than by the number alone. Symptoms, diet, inflammation, albumin, gastrointestinal health, copper status and supplement use may alter the meaning of a low, borderline or unexpectedly high value.
In a Walsh-oriented assessment, plasma zinc may be reviewed with serum copper, ceruloplasmin, urinary pyrroles, whole-blood histamine, homocysteine, vitamin D, CBC and CMP. The appropriate panel depends on the clinical question.
Important Limitations of Plasma Zinc Testing
A plasma zinc test does not diagnose a mood disorder, copper overload, pyroluria or metallothionein dysfunction by itself. It is one laboratory marker that must be interpreted with symptoms and other relevant findings.
A normal plasma result does not always exclude marginal deficiency, and a low result obtained during acute inflammation may not represent long-term zinc status. Repeat testing or broader evaluation may be appropriate when the result does not match the clinical picture.

Frequently Asked Questions About the Plasma Zinc Test
What test checks for zinc deficiency?
Plasma or serum zinc is the most practical blood test for suspected deficiency. Interpretation should account for inflammation, fasting, time of day, albumin and recent supplementation.
Can I order a zinc blood test without a local doctor visit?
This page allows eligible patients to purchase a plasma zinc test online and complete the blood draw through LabCorp using the supplied order.
Do I need to fast for a plasma zinc test?
Follow the specific instructions sent with the laboratory order. Fasting and collection timing can improve consistency.
Should I stop zinc supplements before testing?
Report all supplements and follow the instructions provided with the test. Do not discontinue prescribed treatment without medical guidance.
Should copper and ceruloplasmin be tested with zinc?
They are often useful when copper imbalance, pyroluria, anxiety, hormonal symptoms, prolonged zinc use or a Walsh biochemical pattern is being evaluated.
