The Mineral Screen and Industrial Heavy Metal Screen measures eleven minerals and metals in your blood, from essential nutrients such as zinc, magnesium and iron to toxic metals including lead, mercury and cadmium. It suits people with possible occupational exposure, unexplained symptoms, or anyone wanting a broad check on mineral status and metal exposure. The profile costs £407.50 plus a £50 blood-draw fee, with results back in 7-10 days. You can walk in or book online at 117a Harley Street, seven days a week, with no GP referral needed.
This profile is commonly requested by people who work with metals directly, such as in welding, battery manufacturing, smelting or plating, where regular monitoring forms part of workplace health surveillance.
It's also useful for anyone with unexplained fatigue, gut symptoms, headaches or neurological complaints where a doctor wants to rule metal exposure in or out, particularly if there's a plausible source at home or work.
Some people request it as part of a broader nutritional check, to see whether mineral levels such as zinc, magnesium or iron sit outside what's expected for them.
Most people do not need to fast for this test, and you should follow any specific instruction from your doctor. If you've taken dietary supplements containing any of these minerals recently, or had unusual dietary exposure such as a large seafood meal, mention this to the phlebotomist, as it can affect certain results.
Low readings for minerals such as iron, zinc or magnesium can point towards dietary shortfall, absorption problems or increased demand, while raised readings for toxic metals like lead, mercury or cadmium suggest exposure that needs tracing to its source.
None of these results confirm a diagnosis on their own; your doctor needs to weigh them against your occupation, diet, symptoms and any other testing. Anyone with a significantly raised toxic metal reading should arrange a prompt doctor's appointment rather than wait.
If you would like a doctor to request the right tests for your symptoms or talk the report through, book a private GP consultation at Medical Express Clinic.

Yes, it's often used for occupational monitoring in jobs involving welding, battery work or metal plating, where regular checks on lead, cadmium and mercury are common practice.
Heavy metal analysis needs specialist laboratory methods, which is why results take 7-10 days rather than the 1-2 days typical of routine bloods.
Yes, recent supplement use can raise readings for minerals such as zinc, iron or magnesium, so it helps to mention any supplements to the phlebotomist beforehand.
Book a follow-up with a doctor promptly. They can advise on tracing the source of exposure and whether further action is needed.
