Vitamin D Test Kit

The vitamin D test kit measures the amount of vitamin D found in your blood. It can tell you one of three things:

• You have a normal level of vitamin D
• You have an insufficient level of vitamin D
• You are deficient in vitamin D

If you are deficient in vitamin D, you may have weak bones. You might get these symptoms:

• bone pain or tenderness
• muscle weakness
• a higher risk of fractures
• difficulty in walking

If you are insufficient in vitamin D, you have a low level of vitamin D in your body but you might not experience the symptoms of vitamin D deficiency. It’s still important to treat low vitamin D even if you feel well because having low vitamin D puts you at a higher risk of:

• heart disease
• type 2 diabetes
• some types of cancers
• certain conditions such as multiple sclerosis, allergy, and asthma

If you have low vitamin D levels, you might notice that:

• you get ill more frequently
• wounds on your skin take longer to heal
• you have low mood

People who live in the UK are at risk of having low vitamin D in the winter months. You might be at an even higher risk if you:

• have dark skin
• regularly use sunscreen or wear clothing that conceals your skin
• are elderly
• have a BMI that falls in the obese category
• have kidney or liver disease
• take anti-epilepsy medications

Home testing might be the right option for you if you’d prefer not to make a face-to-face appointment with your usual doctor.

Usually if you are taking vitamin D as advised by a doctor you don’t need to take a test to check you levels, because you should be getting enough vitamin D from your supplements.

If you still want to check your blood levels to see if you are getting enough vitamin D you can take the test.

This result means that you have a low level of vitamin D in your body, but at this level most people don’t have any symptoms. It’s important to treat low vitamin D as it can lead to other health problems. You would only need to take a regular low dose of vitamin D if your test results show that you are insufficient. We call this a Vitamin D Continuation Treatment.

If you are vitamin D insufficient, you can order vitamin D continuation treatment through ZAVA. Remember, you can order vitamin D supplements through our service whether you use our home test kit or go to the GP for a blood test.

If you are vitamin D deficient, you can order vitamin D starter treatment through ZAVA. Remember, you can order vitamin D supplements through our service whether you use our home test kit or go to the GP for a blood test.
