A vitamin D blood test checks how much vitamin D is in your blood. Vitamin D helps your body control calcium and phosphate, which you need for healthy bones, teeth and muscles.
Our private vitamin D test measures 25-hydroxyvitamin D, often written as 25-OH vitamin D. This is the form of vitamin D usually measured to check your vitamin D level. Book online, choose how you’d like your sample taken, and get a clear snapshot of your level on the day of your test.
When your skin makes vitamin D from sunlight, or you get it from food or supplements, your liver turns it into 25-hydroxyvitamin D. This is the main form that circulates in your blood, which is why it is the standard way to check vitamin D status.
This is a single-marker test, so it is a simple, focused way to check your vitamin D level. If you want vitamin D checked alongside other markers, see the wider panel option further down this page.
Low vitamin D is common in the UK, especially in autumn and winter. Many people with low vitamin D have no obvious symptoms. When symptoms do happen, they can include:
These symptoms are common and can have many other causes. Having them does not mean you have low vitamin D. If your symptoms are new, getting worse or worrying you, speak to your GP.
From about October to early March, sunlight in the UK is not strong enough for your skin to make much vitamin D. That is why vitamin D levels are often lower in the colder months.
Not everyone needs a vitamin D test, and the NHS does not usually recommend routine testing for people without symptoms. People often book a vitamin D level test when:
Such as bone or muscle aches, or muscle weakness, and you would like to check your level before speaking to a healthcare professional.
For example, if you spend little time outdoors, usually cover your skin, or have darker skin.
If your GP or another professional has asked you to check your vitamin D, you can book a private vitamin D blood test without waiting.
Book online and choose a Clinic Visit, Home Visit (Essex only) or Kit Only (Venous Blood Collection).
Feeling tired all the time? Tiredness has many possible causes, so a single vitamin D result will not explain it on its own. Our Tired All The Time Blood Test checks vitamin D alongside a wider set of markers.
We want you to know exactly what you’re booking.
Follow the preparation instructions supplied for your specific test and Visit Type.
If you take vitamin D, a multivitamin, other supplements or prescribed medicines, let the Swift Blood Tests team know.

It measures 25-hydroxyvitamin D (25-OH vitamin D) in your blood. This is the main circulating form of vitamin D and the standard way to check your vitamin D level.
25-OH vitamin D, or 25-hydroxyvitamin D, is the form your liver makes from the vitamin D you get from sunlight, food and supplements. A 25-OH vitamin D test is the same as a standard vitamin D blood test.
People often check their vitamin D if they have symptoms that could be linked, such as bone or muscle aches, if they may be at higher risk of low levels, or if a healthcare professional has suggested it. Routine testing is not usually needed for people without symptoms.
A 25-OH vitamin D blood test is how vitamin D levels are checked. What your result means for you, and whether you need any treatment, should be discussed with your GP, pharmacist or another healthcare professional, who will consider your symptoms and history too.
Tiredness can be one of the symptoms linked with low vitamin D, but it has many other possible causes. A vitamin D result on its own will not explain why you feel tired. If tiredness is your main concern, speak to your GP or consider a wider test such as our Tired All The Time Blood Test.
Please follow the preparation instructions supplied for your test and Visit Type. If you’re unsure whether you need to fast, call our team on 01277 652067 before your appointment.
Do not stop or change any prescribed medication or supplements to have this test unless your prescriber or healthcare professional advises it. Supplements can affect your vitamin D level, so let our team know what you take.
