Feeling tired, low in energy, or more prone to illness?
This advanced blood test from Effect Doctors combines our Vitamin & Mineral Deficiency Test with our Iron Deficiency Profile to deliver one of the most thorough health screens available. It’s designed to uncover the root causes of fatigue, low immunity, hair thinning, and poor concentration — helping you optimise your wellbeing with precise, medical insight.
Our clinicians assess your body’s essential building blocks:
-
Vitamins: B12, B9 (folic acid) and Vitamin D
-
Minerals: Magnesium, zinc, calcium, potassium, sodium, and chloride
-
Iron markers: Iron, ferritin, transferrin, TIBC, transferrin saturation
-
Health indicators: CRP (inflammation), FBC (red & white blood cells), Liver and Kidney Function Tests
You’ll have a consultation with one of our doctors, who will review your medical history, blood pressure, and symptoms.
Samples are processed at our trusted laboratory, and results are typically ready within 7–10 working days. Your doctor’s report includes a clear interpretation and recommendations — including, where appropriate, treatment options such as IV iron infusions, vitamin supplementation, or IV nutrient therapy.
Why This Test Matters
Even mild deficiencies in vitamins or iron can have a profound effect on your health. Common signs include:
-
Constant tiredness or brain fog
-
Weakness and low stamina
-
Frequent colds or infections
-
Hair thinning or brittle nails
-
Low mood or difficulty concentrating
These issues are often caused by dietary gaps, malabsorption, inflammation, or lifestyle factors — all identifiable through this test.
