Histamine and DAO Enzyme Analysis – Biomarker Measurement

Complete histamine metabolism diagnostics: histamine load in stool (ELISA) and diamine oxidase activity in dried blood (Dryspot) — both analyses together, done at home, in one shipping bag.

No prescription needed. Ships the next working day.

Sample typeStool + dried blood
MethodELISA, Dryspot
Turnaround7–21 days from sample arrival
AnalysisPartner laboratory in Germany
Evaluation usually takes 7–21 days from the arrival of the sample at the laboratory, not from the order date. We let you know as soon as your results are in.
  • Two methods combined Histamine in stool and the DAO enzyme in dried blood from one kit
  • Finding the cause Shows whether histamine load in the gut or low DAO activity is behind it
  • Sample collection at home Both samples in one shipping bag
  • Results consultation included Evaluation by the expert team

The approach

Measure first, then decide

Without measured values, any treatment is guesswork. We turn that around: the lab report comes first, the decision second.

Consultation to put the measured values in context
  1. 01
    Measure Histamine and the DAO enzyme from stool and dried blood, analysed at a partner laboratory in Germany.
    Histamine and DAO enzyme analysis · Stool + dried blood · 7–21 days from sample arrival
  2. 02
    See where you stand Every value appears in the lab report with the laboratory's reference range. You can see which values fall inside it and which do not.
    Lab report including a consultation
  3. 03
    Targeted, not blanket Instead of a standard package you take what your values call for — agreed with a practitioner.
    Initial consultation, 10 minutes, free
  4. 04
    Measure again after a few months The same analysis a second time shows how the values have changed.
    Earliest sensible interval: 3 months

Ory experts are with you

Doctors and non-medical practitioners from the Ory team are there for you throughout — for the lab report and everything after it.

Initial consultation

What a value means, and whether a supplement is right for you, is something to discuss with a practitioner. This page makes no recommendation and is no substitute for medical assessment.

What this analysis covers

What is measured

Histamine load in stool and diamine oxidase activity in dried blood — together they give a complete picture of histamine metabolism.

T909 Histamine in stool Quantitative ELISA measurement, normal range below 959 ng/ml
Testset 922 DAO enzyme in dried blood Diamine oxidase activity by the Dryspot method

The biomarker reference explains what lies behind the numbers: how values interact, which cofactors are involved and which biochemical processes take place in the body — for all values and areas, not only this analysis.

To the biomarker reference

For whom

The test suits suspected histamine intolerance where the cause is unclear — flushing, headaches, hives, a racing heart or bloating after histamine-rich meals such as red wine, cheese or fermented food.

What a single value means in your situation is something to discuss with a practitioner. It does not replace medical assessment.

How it works

Four steps from order to lab report.

  1. 01 Kit arrives Sent the next working day, postage paid, to your door.
  2. 02 Take the samples A stool sample and a drop of dried blood, both at home.
  3. 03 Send them in Both samples together in the postage-paid bag.
  4. 04 Receive the report 7–21 days after the sample arrives, consultation included.

Instructions

The essentials first:

  • Take the stool sample with the special collection set provided, avoiding contact with toilet water.
  • For the dried blood: disinfect the finger, use the lancet to place a drop on the DrySpot card and let it dry.
  • Send both samples together with the request form in the postage-paid bag.

Please read the instructions carefully. Correct preparation matters: it is what allows your sample – stool, urine, saliva or blood – to be evaluated cleanly and meaningfully.

Sending your sample back

To make sure your sample reaches the laboratory safely, follow the rule for your country.

Country Postage Shipping

In short: Germany, nothing to do. Austria, add a stamp and send to Vienna. Switzerland, add a stamp, use the special bag, send to Germany. Rest of Europe, add a stamp and send to Germany.

Family and partner diagnostics

Testing together shows connections that a single analysis does not reveal. We need three things for it.

Clear details per person For everyone tested we need a name and date of birth so the laboratory can match everything correctly.
A separate email address Each person needs their own email for secure digital access. Where that is not possible, we send the results as a PDF to one shared address.
Clear labelling Samples and forms must each be matched to the right person.

From three tests of the same analysis for the family you get 10 % off. Write to us and you will receive your own discount code.

Reimbursement by private health insurance

If your private health insurance might reimburse you, this is how it works with us:

01 A short online conversation with one of our therapists We go through your symptoms and take a brief medical history.
02 A referral for the matching lab tests After the conversation you receive a referral that you can submit to your private insurer.

Many private insurers cover the cost in full or in part – some not at all. That depends entirely on your policy. We support you through the process as best we can.
