What is Ziwig Endotest® ?
Ziwig Endotest® is an in vitro diagnostic device for use by healthcare professionals only for the diagnosis of endometriosis from a saliva sample.
Ziwig Endotest® is an innovative, non invasive, diagnostic tool based on the analysis of salivary miRNAs via NGS (Next Generation Sequencing) and by Artificial Intelligence (AI).
Ziwig Endotest® is intended for patients between the age of 18 and 43 years with symptoms suggestive of endometriosis1:
- Chronic pelvic pain
- +/- dysmenorrhea
- +/- deep dyspareunia
- +/- dysuria/painful urination
- +/- dyschezia/painful defecation
- +/- painful rectal bleeding or haematuria during menstruation
- +/- pain in the shoulder tip
- +/- infertility
1. The reasons for, or situations in, which someone would use the diagnostic tool
- Patients with suggestive symptoms of endometriosis and when imaging examination results are normal or equivocal, before empirical medical treatment.
- Patients with persistent suggestive symptoms of endometriosis despite medical treatment and when imaging examination results are normal or equivocal.
2. Exclusion Case
- Endometrioma or rectosigmoid endometriosis found on US and/or MRI examination.
Ziwig Endotest® is a prescriptive-use only device, and saliva collection must be done under the supervision of a healthcare professional.
Limitations regarding the population
- The patient must be at least 18 and no more than 43 years of age at the time of testing.
- The patient must not have a history of cancer or Human Immunodeficiency Virus (HIV) infection.
- The patient must not be pregnant at the time of testing.
- Ziwig Endotest® is intended for female patients only.
- Ziwig Endotest® can be performed under hormonal treatment.
- Ziwig Endotest® can be performed at any time of the cycle.
Interpretation of results
Three types of results are possible for Ziwig Endotest®:
- A positive result from the Ziwig Endotest® is in favor of the
presence of endometriosis in the patient. A positive result cannot completely confirm the presence of endometriosis.
- A negative result from the Ziwig Endotest® is in favor of the absence of endometriosis in the patient. A negative result does not completely rule out the presence of endometriosis.
- An invalid result: the sample and/or the sequencing file could not be analyzed or is not interpretable.
Medical management of the patient must be based on all available clinical and biological data.
Possibly allows to put an end to the diagnostic errancy (reducing the average time to diagnosis from 8 years to a few days) but also to improve the overall care of endometriosis by:
Opening the way to early treatment of endometriosis
Allowing to slow down or even stop the aggravation of pain and other symptoms
Optimizing the care of infertility
Limiting the deterioration of patients’ quality of life
Reliable and fast.
Ziwig Endotest® is the possibility of knowing, within a few days and with a reliability close to 100% (sensitivity >95%, specificity >95%, diagnostic accuracy (AUC) of 98%)2, if your patients are suffering from endometriosis.
Simple to use
but based on cutting edge technology.
Ziwig Endotest® requires a simple saliva sample. The diagnosis is made in the laboratory. It relies on Next-generation Sequencing of micro RNA present in saliva and on the use of artificial intelligence to process the very large volume of data generated.
A unique technology accessible to all healthcare professionals.
No matter where you are located, in a large metropolis or in the countryside, Ziwig Endotest® allows you to obtain a simple, reliable and fast diagnosis for your patients.
Shorten wandering and restore hope!
Women affected by endometriosis endure an average of 8 years3 of diagnostic errancy and see approximately 10 doctors4 before being diagnosed.
Put an end to your patients’ uncertainty by providing them with a clear and reliable diagnosis.
Conceived for all cases of endometriosis, including the most complex.
Ziwig Endotest® makes it possible to confirm or eliminate the diagnosis of endometriosis with a high reliability and to distinguish endometriosis from other pathologies with a similar sympthomatology2,5-9. It is particularly indicated in complex cases where medical imaging remains uncertain.
A large clinical study conducted in collaboration with 5 general hospitals.
A study involving 1000 patients to evaluate the value of miRNAs for the diagnosis of endometriosis.
In partnership with
the patient association Endomind.
”"The arrival of Endotest® Diagnostic is a radical change for all women who suffer from pelvic pain. Getting a reliable diagnosis in a few days with a simple saliva sample is a real revolution for them and their medical care."Nathalie ClaryEx-President of the association Endomind
