VITAMIN D (25-OH/D3) BLOOD TEST

Apart from being essential for healthy bones, hair and skin, adequate vitamin D levels are associated with a lower risk of heart disease. It may help regulate blood pressure and reduce inflammation.

Vitamin D is important for muscle strength and function, and deficiency can lead to muscle weakness and pain. Finally, it is important in managing autoimmune diseases, such as multiple sclerosis, rheumatoid arthritis, and type 1 diabetes - these have all been linked to low vitamin D levels.

Vitamin D can be obtained through dietary sources such as fatty fish (e.g., salmon and mackerel), fortified foods (e.g., fortified milk and cereals), and supplements. However, the body can also produce vitamin D when the skin is exposed to sunlight. Therefore, a balance between sun exposure, diet, and supplements can help ensure sufficient vitamin D levels in the body.

DOCTOR'S COMMENTS

Hi, I am Dr. Adam Staten and here's my view on this test as a GP and Clinical Director at One Day Tests.

DR. ADAM STATEN - GP VIEW AND RED FLAG SYMPTOMS

Vitamin D is essential for the absorption of calcium and phosphate from the gastrointestinal tract. These minerals are critical for maintaining strong and healthy bones. Without enough vitamin D, the body cannot absorb enough calcium, leading to weakened bones and conditions like rickets in children and osteoporosis in adults.

Red flag symptoms for the Vitamin D (25-OH) Blood Test

Even if your levels of Vitamin D are normal or low, you should always consult your GP before taking any supplements.

SPECIAL INSTRUCTIONS

Hi, I am Stefania Brown, I am the Laboratory Manager at One Day Tests and here are the lab's special requests for the Vitamin D (25-OH) Blood Test.

SPECIAL INSTRUCTIONS

There are no special instructions for this test, you can take it anytime.

It is important to note that excessive vitamin D intake can lead to toxicity, so it's advisable to consult with a healthcare professional before taking high-dose supplements. Additionally, individual vitamin D requirements can vary, so it is essential to monitor your levels through blood tests if you have concerns about deficiency or excess.

Clinic appointment - how to prepare for the Vitamin D (25-OH) Blood Test

If you are coming into one of our clinics for the test, this is what you need to do before you arrive:

  • Read the instructions in the SPECIAL INSTRUCTIONS section
  • Drink plenty of water about an hour before the appointment.
  • Avoid coffee/tea/energy drinks. Water is good!
  • That’s it! We’ll do the rest.

Home test kit - how it works with the Vitamin D (25-OH) Blood Test

Our blood test kits are simple and convenient.

The most important step in doing a blood test at home is to read the instructions very carefully. The process is very simple, but there are a few pitfalls you need to be aware of - you will save yourself a lot of time if you do it right the first time around!

  • Full printed instructions will arrive with your kit - please read them carefully.
  • Drink plenty before taking the sample and warm your hands up in the sink with warm water for a few minutes. This will make your blood flow much better.
  • Fill the tubes to the top line. We don’t need much blood; filling tubes to the top line is about 15 drops of blood.
  • Post the samples on the same day you take them, before midday, Monday to Thursday. If you post it any other time it might get to us late or be stuck at a sorting office over the weekend. You will then have to do it again.
  • Package the sample in the same box the kit came in. Otherwise, Royal Mail or DPD will reject it. The sample tubes go into a pouch, then into a cardboard box, and then into a return envelope. All of this is provided in the kit: please use it.
