EDIT-B, the first blood test for Bipolar Disorder and Depression

EDIT-B®: Advanced Diagnostic Support for Mental Health

EDIT-B® is a CE marked and patented In Vitro Medical Device (IVD) designed for qualitative differentiation between bipolar disorder and depression. This blood test is specifically intended for use in adult patients (18 years and older), who are experiencing moderate to severe depression symptoms at the moment of the tests and are receiving treatment for their condition.

EDIT-B® is available under the name myEDIT-B in Europe. For more information, please see “Process, partners & Availabilities” below.


Enhancing Clinical Decision-Making

As a blood test, EDIT-B® serves as a critical decision-support tool for psychiatrists and doctors. It aids clinicians by enhancing the diagnostic process and, by doing so, aims to accelerate the selection of appropriate therapeutic treatments. With its innovative approach, EDIT-B®’s ambition is to significantly reduce the common diagnostic uncertainty associated with bipolar disorder, facilitating more targeted and effective treatment strategies.


Proven Effectiveness Through Clinical Trials

Since its inception in 2016, Alcediag has conducted extensive clinical trials involving several hundred patients. EDIT-B® has demonstrated high diagnostic accuracy on several independant cohorts, with both sensitivity and specificity rates exceeding 80%. These trials underscore its reliability and effectiveness in clinical settings. For more information about our clinical trials, please click here.


Advanced Technology for Precise Diagnostics

EDIT-B® leverages cutting-edge RNA sequencing technology combined with Artificial Intelligence (AI) to analyze RNA-editing modification patterns in whole blood. It also incorporates individual patient data such as age, sex, current treatments, and any addictions, to ensure a comprehensive and precise diagnosis.

About Depression & Bipolar Disorder

Mental disorders are classified as one of the 10 most incapacitating pathologies. Depression is one of the most common ones with an estimated 5% of adults or 300 million people suffering from it according to the World Health Organization. Bipolar disorder is one of the most serious with 40 million people diagnosed worldwide in 2019, and a high level of underdiagnosis. In Europe, it is estimated between 2% and 4% of the population is affected by this chronic mental illness.

300 million people worldwide suffer from depression.

Up to 40% of them may actually suffer from an undiagnosed bipolar disorder.

Today, it takes an average of more than 8 years to diagnose bipolar disorder.

Depression is characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in daily activities. Individuals experiencing depression may also struggle with changes in appetite, sleep disturbances, and a pervasive sense of fatigue. This condition can significantly impact not only the individual’s daily functioning but also strain relationships with family and friends.

On the other hand, bipolar disorder is a chronic disease marked by mood swings, cycling between periods of mania or hypomania and severe depression. During manic episodes, individuals may experience heightened energy levels, impulsivity, and a decreased need for sleep. These episodes are followed by depressive periods characterized by the symptoms mentioned earlier. The nature of bipolar disorder can be challenging for both the affected individuals and their loved ones, as it may lead to difficulties in personal and professional lives.

The Current Diagnosis of Bipolar Disorder & its Challenges

Diagnosing Bipolar Disorder

Today, the diagnosis of Bipolar Disorder is mainly based on a psychiatric examination, carried out by a specialist using questionnaires, interviews and several validated scales.

According to NAMI (National Alliance on Mental illness), the typical delay for receiving a diagnosis of bipolar disorder is around 8 years. Several publications highlight the difficulty to accurately diagnose it (Bipolar disorder diagnosis: challenges and future directions): “Bipolar disorder is an especially good example of a group of psychiatric illnesses that are difficult to diagnose accurately. For example, although this disorder, along with other psychiatric illnesses, is one of the ten most debilitating of all non-communicable diseases, misdiagnosis of the illness as recurrent unipolar depression occurs in 60% of patients seeking treatment for depression”.


The consequences of a delayed diagnosis

A delayed diagnosis of bipolar disorder can have profound impacts not only on the patient, but also on their loved ones. When bipolar disorder goes unrecognized or misdiagnosed, patients may suffer through unnecessary hardships and ineffective treatments, exacerbating the emotional and psychological toll and leading to significant disruptions in their personal and professional lives. 

Recognizing the symptoms and seeking a timely diagnosis is crucial for effective treatment and management of both depression and bipolar disorder. An accurate diagnosis allows for the implementation of tailored treatment plans, which may include therapy, medication, or a combination of both. It promotes better outcomes for the patient for mental as well as physical health. Additionally, the support of family and friends plays a vital role in the overall well-being of individuals dealing with these mental health conditions.

In the landscape of Psychiatry, traditionally steered by clinical insights, we now stand on the cusp of Precision Psychiatry. Amidst the global prevalence of bipolar disorder, often under-diagnosed and mis-diagnosed due for example to the absence of manic episodes in some patients, a revolutionary era emerges. With a biomarker signature unveiled through a simple blood test, diagnostics can be turned into a realm of objectivity. This not only addresses the pervasive challenges of accurate identification of Bipolar Disorder but propels us into a future where mental health care is finely tuned to human biology. Beyond a test, it’s a promise of personalized therapies, optimized outcomes, and a brighter path to mental well-being for individuals, families, and society at large.
