Discover your Vitamin D levels.

Vitamin D is responsible for many things: the health of your immune system, your mood, it may lower your risk of cancer, and more.
Some people who may be at risk of a deficiency include:
• Older adults
• People with limited sun exposure
• Vegans and vegetarians
• People with chronic illnesses
Vitamin D is an essential nutrient to nourish your body with, and without it, you may experience serious ramifications to your health and wellbeing. A vitamin D test is the easiest and quickest way to start getting a definitive answer to your worries.

How can a Vitamin D Test help me?

A vitamin D test can help prevent you from disastrous consequences. For example, if you suffer from vitamin D deficiency for long enough, then you may suffer from bone aches, constipation, gum disease, and growth problems.
Vitamin D is essential for every human at every stage of their life. If you’re worried that you’re exhibiting any of the signs of a vitamin D deficiency, then it is prudent that you take a test.
And ultimately, a vitamin D test will give you the peace of mind you’re craving.

Our at home Vitamin D test kit provides you with a fast indication of 25-hydroxy vitamin D (25 (OH) D) levels.

Vitamin D deficiency is associated with many diseases including cancer, cardiovascular disease, autoimmune diseases, diabetes, and depression.

Monitoring your vitamin D levels as a key biomarker and determining whether to take supplements can be an important part of a health regime. High vitamin D is linked to fighting Covid-19 and recovery.

Purchase and Shipping

Following the simple and secure payment process, you will receive free shipping of our CE-approved sample collection kit within 3 working days including easy instructions on how to complete your test.

Sample and Results

Vitamin D levels are tested using a simple blood test that can be completed at home. Just a few spots of blood are required using a pin-prick lancet within the test kit and you will receive results from the lateral flow cassette within 20 minutes.

Why You Should Get a Vitamin D Test

Monitoring your vitamin D levels to determine whether to take supplements can be an important part of regular health reviews and early diagnosis of medical issues. Vitamin D deficiency is associated with many diseases including:

  • Cancer
  • Cardiovascular disease
  • Autoimmune diseases
  • Diabetes

25-hydroxy Vitamin D is the main storage form of vitamin D in the human body. The current status of vitamin D levels can be determined by detecting the content of 25-hydroxy Vitamin D.

25-hydroxy Vitamin D level less than 30ng/mL indicates Vitamin D Deficiency or Insufficiency.

The test provides results based on Normal, Insufficient or Deficient. Both Deficient and Insufficient results can then be used to request a secondary test or consult further medical advice.

Vitamin D Deficiency Symptoms

Vitamin D deficiency is often not obvious in adults as symptoms overlap with other conditions. This is a reason why it is beneficial to complete a test to rule out whether you have a deficiency in vitamin D or not.

Symptoms of vitamin D deficiency are:

  • Muscle cramps / weakness
  • Bone and back pain
  • Poor immune health
  • Tiredness and fatigue
  • Impaired wound healing
  • Depression and anxiety

This test uses a blood test sample, but why?

The at-home collection kit is a 25-hydroxy vitamin D (calcifediol) blood test that is used to determine how much vitamin D is in your body.[1] The blood concentration of calcifediol is considered the best indicator of vitamin D status.[2]

How does this test work?

This test can be used to diagnose vitamin D deficiencies, as well as indicating a higher risk for a vitamin D deficiency. These results can be used as supporting evidence for the beginning of aggressive therapies in such patients.[3]
Patients with osteoporosis, chronic kidney disease, malabsorption, obesity, and a few other infections may be at high risk and have a greater indication from this test.[3] Our lateral flow technology device from Allergy Test provides results based on three categories ‘Deficient, Insufficient or Excess’. Both Deficient and Insufficient results can then be used to consult further medical advice.
