A New Breakthrough in Depression Diagnosis –
Detecting MDD with a Simple IVD Saliva or Blood Test
Discover how the new circRNA RT-PCR detection kit is revolutionizing early diagnosis of Major Depressive Disorder using non-invasive saliva or plasma samples. Learn how this innovative test works and why it's more accurate than traditional methods.

What Is circRNA ?
circRNA stands for circular RNA. It’s a type of molecule found in our body that plays an important role in regulating genes. Scientists have discovered that certain circRNA molecules change when someone has depression.
Using a special test called the circRNA RT-PCR Detection Kit , doctors can now measure these changes from a small sample of plasma (blood) or saliva (spit) . This makes it easier, faster, and less stressful for patients to get tested.
How Does the Test Work?
The process is simple and fast :
- Sample Collection : Saliva or blood is collected.
- circRNA Extraction : The special RNA molecules are isolated.
- RT-PCR Testing : A lab machine reads the biomarker levels.
- Result Scoring : A score is calculated to show risk level.
The results are grouped into three categories :
Result Type | Score Range |
---|---|
Normal | Score < 20 |
Mild to Moderate | 20 ≤ Score < 35 |
Severe | Score ≥ 35 |
Keep in mind : This test helps support diagnosis, but final evaluation should always be done by a trained professional like a doctor or psychologist.
Who Can Benefit ?
- Pregnant and postpartum women.
- IT professionals, pilots, military personnel, police officers, teachers , and others under high stress.
- People with a family history of depression.
- Those who may not recognize their own symptoms.
Why Early Detection Is Important ?
In Europe alone, 11% of people will suffer from MDD at some point — that’s much higher than the global average. Yet many don’t seek help due to stigma, lack of awareness, or misdiagnosis.
With this new test, we can :

Reduce missed cases
Guide personalized treatments
Lower long-term costs and suffering



Major Depressive Disorder (MDD) CircRNA RT-PCR Detection Kit
- Size: 96 Tests (2x48 tests)
- CE approved IVD testing of Depression
- (MDD) CircRNA RT-PCR Detection Kit is a cutting-edge diagnostic tool designed to detect Major Depressive Disorder (MDD).
- Using circRNA biomarkers in human saliva sample and reverse transcription polymerase chain reaction (RT-PCR), this kit provides a highly accurate, non-invasive method for MDD screening.
- Ideal for use in both clinical settings and research, it enables identification of depression, classifications of depression (normal, mild depression, moderate depression or severe depression) and evaluate whether depression treatments (SSRIs & SNRIs, rTMS, Ketamine, ECT, etc) are effective to the patients and doctors can adjust treatment plans based on the test results.
