Samples for the Determination of Total 25-Hydroxyvitamin D Levels Were Stable at Ambient Temperature

Key Points

• To evaluate the stability of 25-hydroxyvitamin D levels when samples are transported at ambient temperature.
• Analysis of 25-OHD levels under different temperature conditions
• Sample shipment and handling protocols
• Quality assurance measures applied during the study
• 25-OHD levels remained stable when shipped at ambient temperature
• Supports the current practices of the Vitamin D External Quality Assurance Scheme (DEQAS)
