A feeling of persistent tiredness or lack of energy that isn’t relieved by rest.
Our rapid test is a simple and efficient way to check your vitamin D levels. The process involves a quick and easy finger-prick blood test.
The test results are provided on the test report in both nanomoles per litre (nmol/L) and nanograms per millilitre (ng/mL) measurements.
When you get your test results, your vitamin D levels will be shown in two measurements: nanomoles per litre (nmol/L) and nanograms per millilitre (ng/mL). The following table shows what your results mean and indicate.
| Vitamin D Level (nmol/L) | Vitamin D Level (ng/mL) | What do your results indicate? | When should I retest? |
|---|---|---|---|
| Less than 25 nmol/L | Less than 10 ng/mL |
Deficient 25(OH)D levels below 25 nmol/L indicate Vitamin D deficiency risk. Consult your doctor or healthcare professional for supplementation advice. |
If you start to take supplements and make diet and lifestyle changes, you may retest in 3–6 months to find out if your levels have improved. |
| 25 to 50 nmol/L | 10 to 20 ng/mL |
Insufficient 25(OH)D levels between 25–50 nmol/L are insufficient/suboptimal. Speak with your healthcare professional for advice on supplementation and lifestyle changes. |
If you start to take supplements and make diet and lifestyle changes, you may retest in 3–6 months to find out if your levels have improved. |
| 50 to 75 nmol/L | 20 to 30 ng/mL |
Adequate Vitamin D levels between 50–75 nmol/L are adequate. Discuss with your healthcare professional for advice on supplements and lifestyle changes to achieve the optimal level. |
If you start to take supplements and make diet and lifestyle changes, you may retest in 6–12 months to find out if your levels have improved. |
| Above 75 nmol/L | Above 30 ng/mL |
Optimal Vitamin D levels above 75 nmol/L are optimal. Maintain current intake and healthy lifestyle. Caution: Levels above 250 nmol/L pose a toxicity risk. |
You may retest annually to monitor your vitamin D levels. |
