Stick on the upper arm, press the button

About 10 minutes, doable on your own. Gentle vacuum draws a few drops of capillary blood into the tube – no lancet, no needle in the vein. Most people barely feel it.

Seal the tube, drop it in the letterbox

The return envelope is addressed and prepaid and goes straight to Limbach Gruppe. Monday to Wednesday is ideal so the sample reaches the lab before the weekend.

Report in the app and as a PDF

Single value or 10 values

Single vitamin D test or the CHIRAYOU baseline test?

A home kit from a drugstore or online shop gives you one vitamin D value. The CHIRAYOU baseline test measures the same 25-OH value plus 9 more blood values from one sample – at a flat price.

Context
No view of B12, inflammation, blood lipids, kidney or liver.
Vitamin D alongside B12, hsCRP, ApoB, blood sugar, kidney and liver.

€99 flat for all 10 values – €9.90 per value. No subscription.

Do I get my vitamin D level?

Yes, absolutely. Your 25-OH vitamin D value is analysed in the accredited Limbach Gruppe lab and explained in plain language. CHIRAYOU is just not a single-value test: from the same sample you get 9 more values.

And my GP?

Keep seeing your GP - CHIRAYOU complements that visit, it doesn’t replace it. The free statutory health check ("Check-up 35") only covers a basic lipid profile and fasting glucose in its blood work, and from age 35 you’re entitled to it just once every three years. 9 of the 10 values we measure aren’t part of it - for example ApoB, hsCRP, vitamin D and vitamin B12. Just take your report along as a PDF to your next appointment.

Included in the test

10 blood values, in everyday language

Vitamin D is the focus. The other nine values come from the same sample – no extra blood.

Vitamin D (25-OH)Bones, muscles, immune system
Vitamin B12Energy, nerves, blood formation
ApoBHeart & arteries
hsCRPSilent inflammation
FructosamineBlood sugar of the last 2–3 weeks
TriglyceridesBlood lipids
Uric acidMetabolism
eGFR (cystatin C)Kidney
Gamma-GTLiver
AlbuminProtein status

What the test does not include

Iron/ferritin, thyroid (TSH), calcium, hormones and the classic lipid profile (LDL, HDL, total cholesterol). Your doctor can add these if needed – just take your report along as a PDF.

Where your value sits

Your number, in context

Many people check their vitamin D level on their doctor’s recommendation – often from midlife on, when bones and muscles get more attention. The PDF report fits into any consultation.

Commonly cited thresholds for orientation. They differ between labs and guidelines – your CHIRAYOU report uses the analysing lab’s range and interprets it following a physician-developed protocol.

< 20 ng/mL
Deficient
Below 20 ng/mL (50 nmol/L). Common in winter – best discussed with a doctor.
20–30 ng/mL
Insufficient
20–30 ng/mL (50–75 nmol/L). Lower range, often room to improve.
30–50 ng/mL
Sufficient
30–50 ng/mL (75–125 nmol/L). Generally considered sufficient.
> 50 ng/mL
Upper range
Above 50 ng/mL (125 nmol/L). From here a conversation with your doctor is worthwhile – especially if you already take vitamin D.

Thresholds are for orientation, not diagnosis.

Already taking vitamin D?

Then the test shows where your level actually sits under your current dose – including whether it is above the lab’s range. You do not need to change anything about your intake for the measurement.

And if the value is low?

  • Your report flags the value, explains it and, where appropriate, recommends talking to your doctor.
  • You download the report as a PDF and take it to your appointment – at no extra cost.
  • If you would rather discuss your values directly, you can optionally add a 20-minute video call at checkout (+€50). Your report is complete at €99 – the call is an option, not a must.
Same lab as a Praxis

Analyzed in a DAkkS-accredited lab. Physician-led.

The convenience does not come from a softer lab. It comes from cutting out the clinic visit - not the rigor behind the result.

Dr. med. Claudia Hennig, specialist in general medicine with an MSc in preventive medicine, is responsible for CHIRAYOU’s clinical protocol – markers, reference ranges and the lab partnership. Every value is placed against the analysing lab’s reference range and explained in plain language. If a value is clearly outside the range, your report says so and recommends talking to your doctor.
