Routine screening of vitamin D is not recommended in asymptomatic individuals.
- Individuals who are asymptomatic but have risk factors should be advised to consider supplements as per the Department of Health Advice on Supplements for at-risk groups
- Monitoring of nutritional supplementation is not required.
- Monitoring of high-dose therapy should be done >3 months after replacement to assess response; however, calcium levels should be checked after one month and more frequently if significant renal impairment is present.
Tests will only be done when they are needed to guide medical care — for example, if:
- The patient has bone problems such as osteomalacia or osteoporosis
- There is evidence of a metabolic bone disease, such as chronic kidney disease–related bone disorder
- The patient has persistent low or high calcium levels in the blood
- A hospital specialist (such as rheumatology, endocrinology, or renal) requests it
