What the test measures

What Vitamin D tells you.

The test measures 25-hydroxyvitamin D, the storage form of vitamin D that reflects what you get from sunlight, food and supplements over the past few weeks. It is the same marker a hospital laboratory uses.

It can…

  • Show whether your level is low, borderline or adequate today
  • Give you a clear starting dose if you need a supplement
  • Track whether a supplement is working, when repeated after 3 to 6 months

It can’t…

  • Explain on its own why you feel tired - iron and folate are often checked alongside it
  • Replace a GP assessment if you have bone pain or repeated fractures
Worth booking if

A good fit if…

  • You feel tired, low or achy and want a starting point
  • You cover your skin, spend little time outdoors or have darker skin
  • You are over 65, pregnant or breastfeeding and want to check your level
  • You take a supplement and want to know it is enough, or too much
See your GP first if

Not the right first step if…

  • Bone pain, muscle weakness or a fracture after a minor fall
  • Kidney disease, sarcoidosis or a condition that affects how you absorb food
A finger-prick test cannot assess an emergency. Call 999 for chest pain, breathlessness or collapse.
Your visit

What happens, start to finish.

About thirty minutes in total, most of it the pharmacist talking you through the result.

1. Book online

Pick your test and a time at Summertown.

2. A few questions

Medicines, symptoms and consent, in the consultation room.

3. One finger-prick

A few drops onto the test cartridge. Less than a flu jab.

4. A short wait

The analyser runs while you wait in the pharmacy.

5. Result explained

Against the UK ranges, with what it can and cannot tell you.

6. Your next step

Printed or emailed result, advice, and a GP letter if one is needed.

Understanding your result

What your result looks like, and what it means.

Your printed and emailed result shows your value on a traffic-light bar like this, with a plain-English line and your next step.
Below 25
25 to 50
Above 50
Deficient
May be too low
Adequate
Example: 62 nmol/L sits in the green band – adequate.
ResultWhat it usually meansWhat we do
Below 25 nmol/LDeficientA daily supplement is advised; we will suggest a dose and when to recheck.
25 to 50 nmol/LMay be too low for some peopleA standard daily supplement (10 micrograms) usually brings this up over the winter.
Above 50 nmol/LAdequate for most peopleNo action needed beyond the NHS advice to consider 10 micrograms a day from October to March.
These bands are the usual UK guide; your printed result shows the exact reference range the analyser uses. Some healthy people fall just outside a range, and one reading is a snapshot. The pharmacist reads your result with your history, and anything that needs confirming goes to your GP with a letter.
Vitamin D FAQ

Common questions, answered.

No. Eat and drink as normal, and keep taking any supplement – tell us what you take so we can read the result properly.

Within your appointment. The pharmacist explains it in our consultation room and you leave with a printed or emailed copy.

For most adults the NHS advice is a 10 microgram daily supplement from October to March, and you do not need a test to do that. A test is useful if you want to know whether you are actually low, whether a higher dose is needed, or whether a supplement has worked.

The pharmacist will recommend a higher loading dose and suggest a repeat test in about three months. If your level is very low with symptoms, we give you a letter for your GP.
