Magnesium – Private Testing in London
The Magnesium is available at Wimpole Street Medical and Dental, our clinic in Marylebone, London W1G. This test is priced at £50. A £50 phlebotomy fee applies per visit for blood collection. It requires a venous blood sample, and results are typically available within 1 day.
Magnesium is involved in over 300 enzymatic reactions including energy production, muscle and nerve function, blood glucose regulation, and bone development. Deficiency is common but often undiagnosed.
Who Should Consider the Magnesium?
Individuals with muscle cramps, tremor, fatigue, palpitations, or insomnia. Those taking proton pump inhibitors, diuretics, or certain antibiotics which can deplete magnesium. Patients with diabetes, alcohol dependency, or malabsorption conditions.
Serum magnesium may appear normal even when total body stores are depleted, as only 1% of body magnesium circulates in the blood. Clinical symptoms should guide supplementation decisions.
A trained nurse collects the blood sample by standard venepuncture, a straightforward procedure that typically takes around five minutes. Our clinic is on Wimpole Street, a short walk from Bond Street and Oxford Circus stations. No GP referral is needed, book online or call 020 7183 0692.
