Measures mercury and creatinine in urine to help assess ongoing or longer-term mercury exposure, as an alternative to a blood test. Sample must be given at a London clinic.
3 biomarkers as listed by Medichecks.
This test measures mercury in urine alongside creatinine, which is used to correct for how concentrated or dilute your urine sample is, giving a mercury-to-creatinine ratio. Unlike a blood test, which mainly reflects recent exposure, a urine test is better suited to picking up ongoing or chronic mercury exposure, since urine is one of the main routes the body uses to eliminate the metal.
With three biomarkers, this sits in the upper range for biomarker count in its size bracket among the tests we track, and its £89 price is close to the typical level for tests of a similar size, sitting only slightly above it. We don't have named competing urine mercury tests logged to compare it against directly.
The main limitation is collection: the provider states this sample isn't suitable for posting, so it has to be given in person at Medichecks' partner clinic (Inuvi Clinic) in London, with no at-home or nurse-visit option. Results are typically available within five days, and every result comes with a doctor's comment.
This test suits people concerned about ongoing or chronic mercury exposure, for example from diet, occupation or environmental sources, who want a test that reflects longer-term buildup rather than a single recent exposure. It pairs naturally with Medichecks' Mercury Blood Test if you want both a recent and a longer-term picture.
Because the sample has to be given in person in London, it's a less convenient option if you can't attend the clinic; the fact sheet doesn't give us a cheaper or more convenient like-for-like alternative to point you to.
You need to visit Medichecks' partner clinic (Inuvi Clinic) in London to give a urine sample, since it isn't suitable for posting. Once it reaches the lab, it's analysed for mercury and creatinine, and a mercury-to-creatinine ratio is calculated. Results are typically available within five days and are reviewed with a doctor's comment before you receive them.
Mercury and creatinine in a urine sample are measured by this £89 test to help assess longer-term mercury exposure, as opposed to the more recent picture a blood test gives. We don't have named peer tests in this comparison group, but its price sits close to the typical range for vitamins and minerals tests of similar size that we track. The sample must be given in person at a London clinic rather than at home.
