Potassium – Private Testing in London
The Potassium is available at Wimpole Street Medical and Dental, our CQC-registered clinic in Marylebone, London W1G. This test is priced at £32. A £50 phlebotomy fee applies per visit for blood collection. It requires a venous blood sample, and results are typically available within 1 day.
This test measures electrolyte levels in the blood. Electrolytes are minerals essential for nerve conduction, muscle function, hydration, and acid-base balance.
Who Should Consider the Potassium?
Individuals on medications that affect electrolyte levels (diuretics, ACE inhibitors). Those with weakness, confusion, irregular heartbeat, or muscle cramps. Patients with kidney disease, heart failure, or dehydration.
Electrolyte results must be interpreted in clinical context, considering medications, hydration status, and kidney function. Even small deviations can be clinically significant.
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, directly opposite Wimpole Street tube station (Piccadilly, Circle, and District lines). No GP referral is needed — book online or call 020 7183 0692.
