About this test

With just a small finger-prick blood sample, our Vitamin D Rapid Home Test Kit checks if your vitamin D levels are sufficient, insufficient, or deficient in minutes using a clear colour card comparison.

Vitamin D is essential for absorbing calcium and phosphorus, supporting healthy bones, teeth, and a strong immune system.

Low levels are common, especially in the UK and Europe, where limited sunlight reduces vitamin D production. People with darker skin are also more likely to have lower vitamin D due to higher melanin, which reduces UV absorption.

A lack of vitamin D can lead to fatigue, muscle weakness, low mood, and an increased risk of conditions like osteoporosis, heart disease, and depression. Regularly monitoring your vitamin D helps you take control of your health, especially during gloomy months or if you have risk factors for deficiency.

This highly sensitive test, easy-to-use home test provides reliable results in minutes, empowering you to seek advice and make informed decisions about supplements, diet, and lifestyle to maintain optimal vitamin D levels.

How to use this test

1
Prepare for the test
Bring the pouch with the test cassette inside to room temperature. Do not open it until you’ve washed your hands with soap and rinsed thoroughly with warm water.
Now, proceed to open the pouch, removing the cassette.
2
Prepare the lancet
Remove the clear plastic cap from the lancet. The lancet is single-use, so be careful not to fire it early.
For best results, you should use your middle finger for the sample. Clean your fingertip using the alcohol pad, then allow it to air dry.
3
Collect the blood sample
From the side where the cap was, firmly press the lancet against your fingertip to draw blood. Massage the finger, keeping your hand down.
Without squeezing the bulb, gently put the capillary dropper in contact with the edge of the blood drop. The blood should be drawn into the bulb automatically. Fill it up to the black line, avoiding air bubbles.
4
Transfer the blood sample
Squeezing the dropper bulb, transfer the blood you’ve collected into the well marked ‘S’ on the cassette.
Wait for the blood sample to be completely dispensed into the cassette.
5
Apply the solution & wait
After the blood sample is completely transferred, unscrew the cap of the buffer solution bottle. Add 2 drops of the solution into the ‘S’ well on the cassette.
Wait for the coloured lines to appear. Do not read results until 10 minutes have passed.
After waiting 10 minutes, pick up the test cassette and the vitamin D colour card provided. Compare the intensity of the ‘T’ line on the cassette with the colour card.
6
Read & interpret the results
If the ‘T’ line is equal to or darker than the 10ng/mL line on the colour card, you’re likely vitamin D deficient.
If the ‘T’ line is darker than the 30ng/mL line on the colour card but lighter than 10ng/mL, your vitamin D levels are insufficient (but not deficient).
If the ‘T’ line is darker than the 100ng/mL line on the colour card but lighter than the 30ng/mL line, your vitamin D levels are sufficient.
If only the ‘T’ line appears, or no lines appear at all, your result is invalid.
