Ziwig Endotest Saliva Test

Analyses a salivary microRNA signature using the Ziwig Endotest laboratory process as part of an assessment for possible endometriosis. The result requires clinician interpretation and should not replace evaluation of persistent pelvic pain or other concerning symptoms.

At a glance

• Sample: Saliva collected with the Endotest kit
• Collection: Collect the saliva sample at home or in a clinic by following the Endotest instructions
• Estimated turnaround: 20 days from laboratory receipt of a suitable  sample

What this test measures

Ziwig Endotest salivary microRNA signature

A multi-marker saliva signature assessed by the Ziwig Endotest laboratory process; individual microRNA targets are not listed on the public TDL page. An in-range or out-of-range result is not a diagnosis by itself; clinicians interpret it using the laboratory range, symptoms, medical history and related tests.

How clinicians use this test

The Ziwig Endotest is intended to contribute to specialist assessment for possible endometriosis. A clinician must combine it with symptoms, examination and any appropriate imaging or other investigations.

Is this the right test for you?

Someone with possible endometriosis symptoms who has discussed the test, its eligibility criteria and its follow-up pathway with an appropriate clinician.

Preparation and collection

Sample quality is important. Follow the Endotest collection instructions exactly and confirm current eligibility requirements with the ordering clinician or Home2Lab before testing.

Understanding your result

The laboratory will report Ziwig Endotest salivary microRNA signature with an assay-specific reference range, threshold or qualitative interpretation. Read the biomarker explanation above for common reasons a result may be high, low, detected or reactive, then use the laboratory comment and clinical context to decide whether repeat or follow-up testing is needed.

Your results and next steps

Review the result with the clinician managing your symptoms. Diagnosis and treatment decisions may still require history, examination, imaging or other investigations.

Limitations

This result is one part of an endometriosis assessment. False-positive and false-negative results are possible, eligibility restrictions may apply, and symptoms still require clinical assessment.

When to get medical help

Severe or rapidly worsening pelvic or abdominal pain, fainting, heavy bleeding, pregnancy-related pain or feeling very unwell needs urgent assessment. Use NHS 111 or call 999 in an emergency.
