• Simple fingerstick – one drop of blood is all it takes, lancet and alcohol pad included in the kit
• Color card for easy reading – compare the test line intensity with the included reference card for a clear result
• Approved for self-testing – CE 0123 certified IVD medical device
• Complete kit – test cassette, lancet, alcohol pad, capillary dropper, buffer and color card included

Why should you know your Vitamin D level?

Vitamin D deficiency is recognized as a global health concern. An estimated 40 % of Europeans have insufficient Vitamin D levels – particularly during autumn and winter when sunlight exposure is limited. A deficiency has been linked to a wide range of health issues:

• Osteoporosis and bone softening (osteomalacia)
• Weakened immune system and increased susceptibility to infections
• Fatigue, mood changes and depression
• Muscle pain and weakness
• Increased risk of cardiovascular disease and diabetes

The Vitamin D rapid test lets you check your status at any time – for example, before starting supplementation or to monitor your levels during intake.

How the Vitamin D test works

1. Wash your hands – thoroughly with soap and warm water.
2. Prepare the test – bring the pouch to room temperature, open and place the cassette on a clean surface. Use within one hour.
3. Disinfect your fingertip – clean your middle or ring finger with the included alcohol pad and let it air dry.
4. Collect the blood sample – prick with the lancet, massage the finger. Draw blood into the capillary dropper (to the fill line).
5. Apply the sample – release blood into the specimen well (S). Add 2 drops of buffer into the buffer well (B).
6. Read the result – after 10 minutes. Compare the T line intensity with the Vitamin D color card included in the kit. Do not read after 20 minutes.

How to read your results

Vitamin D status	25(OH)D level	Test display	Recommendation
Deficient	0–10 ng/ml (0–25 nmol/L)	Clear T line, matches “Deficient” on color card	Consult a doctor, discuss Vitamin D supplementation
Insufficient	10–30 ng/ml (25–75 nmol/L)	Medium T line, matches “Insufficient” on color card	Vitamin D supplementation recommended
Sufficient	30–100 ng/ml (75–250 nmol/L)	Faint T line, matches “Sufficient” on color card	Vitamin D level within normal range
Excess	>100 ng/ml	C line only, no T line	Consult a doctor – Vitamin D level may be too high

Important: The higher your Vitamin D level, the lighter the test line. Always compare with the color card included in your specific kit.

Frequently asked questions

How accurate is the Vitamin D rapid test?

In clinical studies with 90 whole blood specimens, the test demonstrated an overall accuracy of 94.4 %. The accuracy for detecting Vitamin D deficiency exceeds 99.9 %. For a precise ng/ml value, we recommend a follow-up laboratory analysis.

When should I test my Vitamin D level?

Particularly recommended during autumn and winter (October–March), with limited sun exposure, before starting Vitamin D supplementation, or to monitor levels during ongoing intake. The test can be performed at any time of day.

What does an “insufficient” result mean?

A Vitamin D level below 30 ng/ml is considered insufficient. This means Vitamin D supplementation is advisable. Discuss the appropriate dosage with your doctor or pharmacist.

Does this test work differently from other rapid tests?

Yes. With the Vitamin D test, a higher Vitamin D level produces a lighter test line. This is the opposite of most rapid tests where a clear line indicates a positive result. Always use the color card included in your kit for accurate interpretation.

Are volume discounts available for clinics and pharmacies?

Yes. We offer tiered pricing for larger orders. Contact us for a customized quote.
