Vitamin A
The Vitamin C lab test, also known as the ascorbic acid test, is essential for assessing an individual's plasma or serum concentration of this vital water-soluble vitamin. Vitamin C plays a crucial role in collagen synthesis, neurotransmitter production, and the metabolism of tyrosine and folate, while also acting as an antioxidant to combat aging and infections. The primary aim of this test is to evaluate Vitamin C nutritional status, particularly for diagnosing and monitoring deficiencies that can lead to scurvy, characterized by blood vessel fragility and connective tissue damage. The test requires a plasma specimen collected in a green-top tube with sodium or lithium heparin, processed within four hours, and protected from light. Advanced techniques like LC-MS/MS and UPLC with electrochemical detection are used for precise measurement. Results are reported in mg/dL or μmol/L, with levels below 0.2 mg/dL indicating deficiency. Proper collection and handling are crucial for accurate results, aiding healthcare providers in diagnosing and managing Vitamin C-related health issues.

The lab test for Vitamin C assesses plasma or serum concentrations of this essential vitamin, crucial for collagen synthesis, neurotransmitter production, and antioxidant functions. Its primary purpose is to evaluate nutritional status and diagnose Vitamin C deficiency, which can lead to scurvy.
- Specimen Collection: Use a green-top tube with lithium heparin; separate plasma immediately.
- Processing: Place on dry ice within 4 hours; freeze plasma in an amber vial.
- Methodology: LC-MS/MS or UPLC with electrochemical detection.
- Interpretation: Normal range is 0.2-2.3 mg/dL; deficiency is below 0.2 mg/dL.
The Vitamin A blood test is essential for assessing retinol levels, crucial for vision, skin health, and immune function. It diagnoses both deficiency and toxicity, impacting health significantly. Key points include:
- Purpose: Evaluates vitamin A status to manage related conditions.
- Preparation: Requires fasting and abstaining from alcohol.
- Collection: Blood drawn via venipuncture, handled carefully.
- Interpretation:
- Normal: 20-60 mcg/dL.
- Low: Below 20 mcg/dL, indicating deficiency.
- High: Above 120 mcg/dL, indicating toxicity.
- Applications: Diagnoses deficiency, detects toxicity, monitors therapy, and screens for related conditions.
Understanding test results for Vitamin C levels is essential for evaluating nutritional status and identifying deficiencies. Here's a concise overview:
- Normal Range: 0.2-2.3 mg/dL or 11.36-130.59 μmol/L.
- Deficiency: Below 0.2 mg/dL or 11 μmol/L, indicating risk for scurvy.
- Moderate Risk: 11-23 μmol/L, suggesting inadequate stores.
- Excess: Above 3.0 mg/dL may cause gastrointestinal issues.
Proper interpretation aids in diagnosing conditions like scurvy and managing health effectively.
