At-home lab tests can measure certain biological markers—such as hormones, vitamins, or inflammatory indicators—that research has linked to mood regulation. Emerging evidence suggests associations between imbalances in these markers (e.g., cortisol, vitamin B12, folate) and depressive symptoms, though findings are often mixed, preliminary, or correlative (Kennis et al., 2020; Moncrieff et al., 2022; Almeida et al., 2015; Petridou et al., 2016).
Importantly, no at-home test can diagnose depression or any mental health condition. These provide informational insights only and should be discussed with a licensed healthcare provider. These tests are NOT FDA-approved for diagnosing or treating any mental health condition.
Research explores several markers potentially tied to mood:
- Cortisol → Often assessed via saliva or urine; chronic elevation may link to stress responses (Kennis et al., 2020).
- Vitamin B12 & Folate → Low levels associated with depressive symptoms in some studies, especially in older adults (Almeida et al., 2015; Petridou et al., 2016).
- Inflammation Markers (e.g., hs-CRP) → Elevated levels sometimes observed in mood disorders.
- Other Nutrients/Hormones → Including vitamin D, thyroid hormones, or NAD+ precursors.
Note: Direct neurotransmitter measurement (e.g., serotonin, dopamine) in peripheral samples has limited clinical validity for mood assessment (Moncrieff et al., 2022).
These CLIA-certified kits focus on evidence-linked markers.
