Repeated Measurements of Vitamin D: Common and Very Unlikely to Indicate Deficiency

Key Points

• The study aims to evaluate the frequency of vitamin D testing and its correlation with actual deficiencies.
• Analyzed frequency of vitamin D tests conducted in a clinical setting.
• Identified instances of low vitamin D levels from the test results.
• Assessed the effectiveness of limiting tests to those at risk of deficiency.
• Most repeated tests show adequate vitamin D levels.
• Limiting tests may reduce unnecessary vitamin D assessments.
• Targeting at-risk populations can enhance testing efficiency.
