How much does Lead (Blood) cost at Wimpole Street?

£71 — the standard price that applies to everyone. There is no discounted members’ tier at Wimpole Street and nothing to join. Where a venous draw is needed, a phlebotomy fee is shown on the page before you book and is charged once per visit however many tests are taken.

Are hair mineral analyses offered?

No. Hair analysis has poor reproducibility and is influenced by shampoos, dyes and environmental contamination, so it is not recommended by toxicology bodies for assessing exposure. Blood and urine measurements are used instead.

How long do toxicology results take?

Metals are analysed by specialist mass spectrometry and are typically reported within one to two weeks of reaching the laboratory. Alcohol markers such as PEth and CDT usually take around a week, while urine drug screens are faster, often two to three days.

Can these tests be done for children with suspected lead exposure?

Medical services at Wimpole Street are for patients aged 16 and over. Suspected lead or other metal exposure in a child should be reported to the NHS GP promptly, as children are more vulnerable and public health follow-up may be needed.

Can I use a PEth result for a court or licensing matter?

Clinical PEth testing gives a reliable indication of alcohol intake over the preceding weeks, but legal proceedings often require a chain-of-custody sample collected under witnessed conditions. Please ask before booking so that the correct process is arranged; a standard clinical report may not be accepted.

Should I test blood or urine for heavy metals?

It depends on the metal. Blood lead is the standard measure for lead; mercury and arsenic are often assessed in urine, which reflects recent exposure; cadmium in urine reflects long-term body burden. The nurse can advise which sample suits your question, or both can be taken.

What Lead (Blood) measures

Lead (Blood) is most often requested in connection with heavy metal poisoning, toxicity and pediatric health, which is why it sits within the heavy metals and toxicology group at Wimpole Street.

Toxicology tests measure metals and chemicals that can accumulate in the body — lead, mercury, arsenic, cadmium, aluminium, thallium and others — in blood or urine, depending on which reflects recent exposure and which reflects body burden. Solvent metabolites such as toluene and xylene breakdown products in urine assess occupational exposure, while alcohol markers (PEth, CDT, urine EtG) and drug screens for cannabinoids, cocaine, opiates and others detect use over different windows. Porphyrin tests and carboxyhaemoglobin address particular poisoning and metabolic questions.

Who considers Lead (Blood)

People often consider metal testing if they work in construction, battery manufacture, painting or metal recycling, or renovate older properties.
Those who eat large amounts of tuna, swordfish or other predatory fish sometimes check mercury.
Unexplained abdominal pain, tingling in the hands and feet or cognitive changes occasionally prompt a heavy metal screen.
Alcohol markers are frequently needed for driving licence medicals, family court proceedings or personal monitoring of a period of abstinence.
Employers and individuals may request drug screens for workplace or legal reasons.

Preparing for your Lead (Blood)

1Avoid seafood for 48 to 72 hours before mercury or arsenic testing, as a single meal can produce a spurious high.
2For urine metals, a random sample is usually acceptable but an early morning sample reduces dilution effects; follow any instruction about collection containers.
3Tell the nurse about supplements, herbal remedies and Ayurvedic or traditional medicines, some of which contain metals.
4For legal or workplace screening, ask about chain-of-custody arrangements before booking, as standard clinical tests may not meet evidential requirements.

Sample for this test: venous blood sample (EDTA).

Understanding your Lead (Blood) results

A metal concentration above the reference range can indicate exposure beyond typical background levels and, at higher values, a risk of toxicity that requires occupational health or clinical review. Because many metals are cleared quickly from blood, urine levels or a repeat after removing the suspected source help to distinguish a one-off exposure from ongoing accumulation. Alcohol markers are interpreted by window: EtG reflects the previous few days, PEth roughly two to four weeks and CDT longer-term heavy intake.

Toxicology results depend heavily on the timing of exposure and the sample type, and reference ranges describe population background rather than a threshold of harm for every individual.
