Found my vitamin D deficiency

I'd been exhausted all winter and the vitamin D result explained everything — it was well below range. A simple finger-prick and now I'm supplementing with a clear target to hit.

Simple and revealing

Just wanted my vitamin D and B12 checked and this was perfect. The B12 was lower than I expected, which finally explained the fatigue and brain fog I'd been getting.

Great budget check

An affordable way to check the two vitamins that matter most for energy and bones. Quick result and clear guidance on where my levels should be.

How to prepare for your test

Before your test

  • Take your sample first thing in the morning, before breakfast — this gives the most accurate readings for cholesterol, glucose, and hormones
  • Water is fine beforehand — stay well hydrated the day before and on the morning of your test
  • Ideally collect before 10 am, when hormone levels are at their baseline
  • Avoid alcohol for at least 24 hours before your test
  • If you take regular medication, take it as normal unless told otherwise by your GP
  • Avoid intense exercise the evening before — it can temporarily affect some markers

If you’re using the finger-prick home kit

  • Warm your hands under warm water for 2–3 minutes before collecting
  • Use the side of your ring or middle finger (not the tip) for the best blood flow
  • Let gravity help — keep your hand below your heart while collecting
  • Gently massage your finger towards the tip; don’t squeeze hard
  • Fill the tube to the marked line — an underfilled sample may need repeating

When to post your sample: Post your sample on the same day you collect it, Monday to Wednesday. Royal Mail typically delivers next day, so your sample arrives at the lab fresh. Avoid posting on Thursdays, Fridays, or before a bank holiday to prevent your sample sitting in transit over the weekend.

Watch video: how to collect your sample

If you’ve booked a nurse visit

  • A qualified nurse will come to your home at your chosen time
  • The venous draw takes around 5 minutes — quick and straightforward
  • Wear a short-sleeved top or loose sleeves for easy access
  • After the nurse collects your sample, simply package it using the prepaid envelope included in your kit and drop it at a postbox the same day
  • Venous samples provide the lab with a larger, higher-quality sample for the most reliable results

Posting after a nurse visit: The same posting rules apply — send your sample the same day, Monday to Wednesday, to ensure it reaches the lab promptly.

After your test

  • Results are typically ready within 2 working days
  • You’ll receive a notification when your results are available in your dashboard
  • Each marker comes with a personalised explanation of what it means for you
  • If you use a health wearable (Apple Watch, Oura, Whoop, Garmin, etc.), connect it in your account after placing your order — we’ll combine your blood data with daily metrics like sleep, activity, and heart rate for deeper, more personalised insights
