Assess your essential trace element levels or screen for potential toxicity with a private Selenium blood test at Medical Diagnosis Victoria (MDX Victoria) in London.
This test measures selenium concentrations circulating in your bloodstream. Selenium is a vital nutrient that plays a central role in antioxidant defence, healthy thyroid hormone metabolism, and immune system function. Measuring blood levels is essential for diagnosing nutritional deficiencies, monitoring patients receiving dietary supplementation or parenteral nutrition, and investigating suspected overexposure in toxicological evaluations.
With a 10-day turnaround, this targeted screening delivers the reliable clinical data your doctor needs to evaluate your trace mineral balance and guide safe, effective care.

Diagnostic Focus
What is the Selenium Blood Test?
Selenium is an essential trace element that is absolutely vital for human health. It plays a foundational role in antioxidant defence, thyroid hormone metabolism, and maintaining a robust immune system. Because the body cannot produce selenium, it must be obtained through diet or supplementation. However, selenium exists in a narrow therapeutic window—meaning both a deficiency and a toxic excess can lead to significant clinical complications. This targeted blood test provides an accurate quantitative measurement to guide precise nutritional and metabolic care.
Thyroid & Metabolism
Evaluating this mineral is essential for:
- Assessing thyroid hormone conversion
- Investigating unexplained chronic fatigue
- Supporting metabolic rate regulation
- Monitoring autoimmune thyroid disorders
Antioxidant & Immunity
This test is highly useful because it:
- Evaluates cellular oxidative stress
- Assesses nutritional immune support
- Monitors trace elements in malabsorption
- Identifies underlying dietary deficiencies
Toxicity & Overload
The laboratory provides critical data to:
- Investigate symptoms of “selenosis”
- Monitor high-dose antioxidant supplementation
- Assess long-term parenteral nutrition (TPN)
- Evaluate suspected industrial overexposure
Clinical Uses
Why is Blood Testing for Selenium Important?
Because maintaining the exact right balance of selenium is critical, guessing your levels can be dangerous. A deficiency can impair immune function and exacerbate underlying thyroid issues, while excessive accumulation—most often resulting from over-supplementation—can lead to toxic accumulation (selenosis) causing nerve, skin, and hair damage. A precise blood test provides the clinical clarity needed to adjust your intake safely.
Evaluating Physical Symptoms
You should consider this test if you are experiencing unexplained symptoms associated with selenium imbalances, such as:
- Signs of Deficiency: Profound fatigue, muscle weakness, frequent infections, or cognitive fog.
- Signs of Toxicity (Selenosis): Unexplained hair loss, brittle fingernails, gastrointestinal distress, fatigue, and a characteristic garlic-like odour to the breath.
Ongoing Medical & Nutritional Monitoring
Doctors frequently recommend serum selenium testing to manage specific health groups, including:
- Patients with thyroid conditions (such as Hashimoto’s thyroiditis) assessing their nutritional co-factors.
- Individuals on long-term total parenteral nutrition (TPN) or those with severe gastrointestinal malabsorption (e.g., Crohn’s disease).
- People taking high-dose antioxidant or trace mineral supplements to ensure they remain within safe thresholds.

Pathology Reports
How To Read Your Laboratory Results
Your report will display your serum selenium concentration measured against optimal reference intervals. Lower-than-normal levels generally point to poor dietary intake, soil depletion in your region, or severe gastrointestinal malabsorption. Elevated levels strongly suggest over-supplementation or, more rarely, environmental overexposure. Because selenium interacts closely with iodine and thyroid function, your doctor will interpret these results alongside your broader clinical picture.
Results Timeline: Your specialist biochemistry report is typically available within 10 days of your blood draw.
Medical Consultation
Need Help? Private GP Consultations
Trace mineral imbalances require thoughtful clinical review. If your test demonstrates abnormal selenium levels, or if you are troubled by persistent fatigue, hair loss, or thyroid concerns, we offer private GP consultations on site. Our clinical team can review your report, arrange complementary thyroid or general nutritional panels, and provide expert guidance on safe dietary modifications and supplementation.

Frequently Asked Questions
Do I need to fast before the test?
No special fasting is strictly required before a selenium blood test. However, if you take multi-mineral or standalone selenium supplements, we highly advise waiting until after your blood draw to take your daily dose to ensure an accurate baseline reading.
How does selenium affect the thyroid gland?
The thyroid gland contains more selenium per gram of tissue than any other organ in the body. It is fundamentally required to produce the enzymes that convert the inactive thyroid hormone (T4) into the active form (T3) that your cells can use for energy.
How quickly will I get my results?
Because precision trace mineral measurement requires specialised laboratory instrumentation and careful processing, your comprehensive results will be securely delivered within 10 days.
Is the phlebotomy fee included in the £51.00 price?
No, the £24.00 phlebotomy service fee is separate and covers the professional process of drawing your blood at our clinic, ensuring clear pricing and no hidden costs.
What is selenosis?
Selenosis is the medical term for selenium toxicity. It almost always occurs from chronic over-supplementation rather than diet alone. Symptoms include gastrointestinal distress, hair loss, white spots on brittle nails, fatigue, and a distinct garlic odour on the breath.

Most Searched Online Questions About Selenium
What foods are highest in selenium?
Brazil nuts are exceptionally high in selenium—in fact, eating just one or two Brazil nuts a day is often enough to meet your entire daily requirement. Other good sources include organ meats, seafood (like tuna and halibut), and whole grains grown in selenium-rich soils.
Can abnormal selenium levels cause hair loss?
Yes. Interestingly, both a severe deficiency in selenium (which can impair thyroid function) and a severe toxic excess (selenosis) can cause significant hair thinning and loss. This is why testing is crucial before beginning high-dose supplements.
Who is most at risk of selenium deficiency?
Individuals living in regions where the soil is severely depleted of selenium, patients undergoing kidney dialysis, individuals living with HIV, and those with severe gastrointestinal conditions (like Crohn’s disease) that prevent nutrient absorption are at the highest risk.
