Biomarker/Parameter Tested with this Vitamin D Blood Test Kit
Vitamin D
Find out what your vitamin D levels are by simply collecting blood using this finger-prick kit and sending the sample to the lab for processing. The report will be quantitative, including actual figures and remarks for any results that fall outside the normal range.
The vitamin D blood collection kit contains everything you need to collect blood and send it to our laboratory for analysis. Inside, you'll find lancets, instructions, lab request form, labels, tube, tube pouch, prepaid UN3373 envelope, tube holder, swabs, alcohol wipes, and plasters. No need to go to the post office; simply drop off your sample in the nearest red letterbox.
For a Vitamin D test, it's important to avoid taking Vitamin D supplements for at least 1-2 weeks before the test. This period without supplementation is known as a washout period. This allows your Vitamin D levels to return to their natural state, ensuring that the test results accurately reflect your body's Vitamin D status.

Vitamin D
What is Vitamin D?
Vitamin D, nicknamed the "sunshine vitamin", is important for keeping your bones and muscles strong, and may even influence your mood! Our bodies can naturally make vitamin D from sunlight, but some people don't get enough sun exposure or may have darker skin tones that make it harder.
- Strong Bones and Teeth: Vitamin D helps your body absorb calcium, essential for building strong bones and teeth. Without enough vitamin D, bones can become weak or brittle.
- Muscle Support: Vitamin D is needed for proper muscle function and may help prevent falls, especially in older adults.
- Sunshine or Food: We get vitamin D from sunlight exposure or by eating foods like fatty fish, egg yolks, or fortified milk and cereals.
If you're worried about getting enough vitamin D, talk to your doctor. They can do a simple blood test to check your levels and advise on getting more sunshine, adjusting your diet, or taking supplements if needed.
Vitamin D Deficiency
Vitamin D deficiency is prevalent in the UK, particularly during winter when sunlight exposure is minimal. Factors such as spending more time indoors, wearing sunscreen and having darker skin pigmentation can further contribute to vitamin D deficiency.
General Symptoms of Vitamin D Deficiency include:
- Fatigue: This is a very common symptom of vitamin D deficiency and can range from mild tiredness to feeling constantly drained.
- Bone Pain and Muscle Weakness: Vitamin D plays a crucial role in bone health, and deficiency can lead to weakened bones and muscles, causing aches and pains.
- Feeling Down or Depressed: Some studies suggest a link between vitamin D deficiency and mood changes, such as feeling down or depressed.
Recommendations for Vitamin D Intake
To maintain optimal vitamin D levels, it's recommended that individuals in the UK consider the following:
- Sunlight Exposure: Try to spend some time outdoors during the sunniest part of the day, with arms and legs exposed, to allow the skin to produce vitamin D.
- Dietary Sources: Include vitamin D-rich foods in your diet, such as oily fish (e.g., salmon, mackerel, sardines), eggs, fortified foods (e.g., fortified dairy products, breakfast cereals), and supplements if necessary.
- Supplements: Consider taking a vitamin D supplement, particularly during the winter months or if you have limited sun exposure. Public Health England recommends that everyone over the age of one should consider taking a daily supplement containing 10 micrograms of vitamin D, especially during autumn and winter.
