Red Cell Copper

The red cell copper test is essential for evaluating copper levels within red blood cells, offering insights into copper homeostasis. It is particularly useful for:

- Monitoring copper exposure
- Diagnosing copper deficiency or toxicity
- Assessing conditions like Wilson's disease and Menkes disease

Specimen requirements include:

- Blood collected in royal blue (K2EDTA or NaHep) tubes
- Centrifugation within 2 hours

Storage guidelines:

- Room temperature or refrigerated
- Avoid clotted or hemolyzed specimens

Performed using ICP-MS, results are available within 1-4 days, aiding in effective diagnosis and treatment.

Understanding test results for the red cell copper test is crucial for interpreting copper levels within red blood cells. Here's a brief overview:

- Purpose: Evaluates intracellular copper stores and homeostasis.
- Interpretation:
- Low levels may indicate deficiency or impaired metabolism.
- High levels could suggest excessive exposure or toxicity.
- Clinical Relevance: Useful for diagnosing conditions like Wilson's disease and monitoring treatment effectiveness.
- Considerations: Results may be affected by specimen handling; prompt separation from plasma is essential.

Understanding these results aids in effective diagnosis and management of copper-related disorders.
