The Importance of Lab Testing for Mental Health

Feeling anxious, depressed, or burnt out can be incredibly overwhelming and impact your quality of life. Often, these feelings can be a sign of underlying imbalances in the body that can be uncovered through comprehensive lab testing. As a healthcare provider, I use lab testing to identify the root causes of mental health concerns and help my patients achieve optimal health.

Why Lab Testing is Crucial

Mental health is a complex interplay of various factors, including genetics, environment, lifestyle, and biochemical imbalances. While therapy and medication are common treatments, they may not address the root causes of your symptoms. Lab testing can provide insights into what's happening inside your body, offering a clearer picture and helping to tailor treatments more effectively.

Why Trends in Labs are Important

If you've ever been told your labs are "normal" despite feeling unwell, you know how frustrating that can be. Lab ranges are based on population averages, so it's crucial not just to focus on flagged results but also to consider trends. Are your results consistently on the higher or lower end? How have they changed over time? Regular lab testing, at least annually, helps track these trends, offering valuable insights into your health and providing a reference point for future changes.

Key Lab Tests to Consider

Here are some essential lab tests that I often recommend in my practice:

1. Complete Blood Count (CBC)

The CBC test is a comprehensive blood test that helps detect a wide range of disorders, including anemia and infection. Both conditions can significantly impact your mood and overall well-being.

For example, anemia, which is characterized by a low red blood cell count or low hemoglobin levels, can lead to feelings of exhaustion, weakness, and even anxiety. This condition is particularly common in women, especially those who experience heavy menstrual periods. If your CBC shows signs of anemia, it’s crucial to address it through diet, supplements, or other treatments to improve your energy levels and overall well-being.

2. Comprehensive Metabolic Panel (CMP)

The CMP assesses your electrolytes, liver and kidney function, and blood sugar levels. Imbalances in these areas can start to affect your mood and mental health.

For instance, electrolyte imbalances can cause symptoms like fatigue, confusion, and irritability. Similarly, abnormal liver or kidney function can lead to toxin buildup in the body, which can manifest as fatigue or mood disturbances. Blood sugar levels are also critical; imbalances here can cause mood swings, irritability, and energy crashes. By identifying and correcting these issues, you can support your body’s overall function and improve your mental health.

3. Ferritin

Ferritin measures your iron reserves, providing insight into your body's iron levels. Low iron levels can lead to significant feelings of anxiety, fatigue, and a low mood. Iron is crucial for oxygen transport in the blood, and insufficient levels can lead to poor oxygenation of the brain, affecting cognitive function and mood.

Most people feel their best when Ferritin is at least 50 ng/mL, however, most lab tests won’t flag Ferritin as low until it’s less than 15 ng/mL for females! That’s a huge range and by tracking your ferritin trend, you can start to build up your iron stores before developing anemia.

Iron deficiency is particularly relevant for women due to factors like menstruation and pregnancy, which can deplete iron stores. When your body doesn’t have enough iron to produce adequate hemoglobin, the protein in red blood cells that carries oxygen, you may start to feel tired, weak, and mentally sluggish. Addressing iron deficiency through diet, supplementation, or other methods can significantly improve your energy levels and mental clarity.

4. Vitamin D

Low levels of Vitamin D are associated with depression and anxiety. However, it's crucial to test before supplementing, as too high a dose can be harmful. Vitamin D plays a role in the production of serotonin, a neurotransmitter that regulates mood. Therefore, maintaining optimal levels can be beneficial for mental health.

5. Thyroid Markers (TSH, fT3, fT4)

These markers help determine your thyroid function. The thyroid gland plays a significant role in regulating metabolism, energy levels, and mood. Hypothyroidism can result in a low mood, while hyperthyroidism might make you more anxious. Proper thyroid function is essential for mental clarity and emotional stability.

Thyroid function tests that more than a TSH (Thyroid Stimulating Hormone), but also look at your thyroid hormones fT3 (free Triiodothyronine), and fT4 (free Thyroxine), are essential for assessing your thyroid health. Without seeing these numbers in ratio it is difficult to properly assess if the thyroid needs more support. If these tests reveal an imbalance, addressing it through diet, lifestyle changes, or medication can lead to significant improvements in your mood and energy.

6. AM Cortisol

Cortisol, often referred to as the stress hormone, follows a specific daily rhythm, with levels peaking in the morning and declining throughout the day. Abnormal cortisol patterns, such as elevated levels at night or low levels in the morning, can lead to significant mental health issues, including anxiety, depression, and chronic fatigue.

Testing your cortisol levels in the morning (AM cortisol) can help determine whether your body’s stress response is functioning properly. If your cortisol levels are out of balance, interventions such as stress management techniques, lifestyle changes, or supplements can help restore balance and improve your overall mental health.

7. Inflammation Markers (CRP, ESR)

Chronic inflammation is increasingly recognized as a contributor to mental health issues, including depression and anxiety. Inflammatory markers like C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) can provide valuable insights into whether inflammation is playing a role in your symptoms.

Elevated levels of CRP and ESR suggest that inflammation may be exacerbating your mental health issues. Addressing chronic inflammation through dietary changes, supplements, or other interventions can help reduce symptoms of depression and anxiety, leading to improved mental and physical health.

8. Homocysteine and Vitamin B12

Homocysteine is an amino acid that, at elevated levels, can increase the risk of cardiovascular disease and affect brain health. It’s also a marker of nutrient deficiencies, particularly in B vitamins like B12 and folate, which are crucial for brain function and mental health.

Low levels of vitamin B12 can lead to symptoms such as fatigue, depression, and cognitive decline. Testing for homocysteine and B12 levels can help identify these deficiencies and guide appropriate supplementation or dietary changes. Correcting these deficiencies can have a profound impact on your mental clarity, energy, and mood.

Why Functional Ranges Matter

It's essential to find a healthcare provider who reads lab results through a functional lens. This approach focuses on optimal health rather than just falling within the "normal" range. Conventional lab ranges are based on averages from the general population, which may include unhealthy individuals. By looking at lab results this way, we can identify and address imbalances more effectively before they develop into chronic conditions.

Working with a Provider
