Description: Vitamin C testing may be used to determine Vitamin C deficiency. Vitamin C is needed for growth, development and repair of all body tissues. Vitamin C deficiency may be due to malnutrition (scurvy), malabsorption, alcoholism, kidney failure, hyperthyroidism and increased need due to pregnancy. Turnaround time for the Vitamin C testing results is typically 2-3 business days.
Requirements: Overnight fasting is preferred for the Vitamin C test. Refrain from taking vitamin C supplements or eating fruit 24 hours prior to sample collection.
