Heavy Metal Test

Why take the Heavy Metal Test?

Toxic heavy metals such as arsenic, lead, cadmium and mercury enter the environment in various ways, into the air we breathe, as well as into soils and plants. Heavy metals can accumulate in your body when you consume contaminated food or drinking water through household objects. In the long run, a build-up of heavy metals can lead to chronic poisoning and damage your nerve cells, liver and kidneys, among other things.

If you know which heavy metals you are exposed to, you can specifically look out for possible sources of pollutants – and avoid them in the future.

How does the test work?

The Heavy Metal Test is a simple urine test. Collect a small amount of urine with a collection cup and a transfer pipette. You then send the urine sample in a collection tube to our certified specialist laboratory. A few days later, you will receive a notification that your results report is ready by email – you’ll find your personal report by logging in to your account on My cerascreen.

What will the results tell me?

In the results report, you will find the concentration of the following metals measured in your urine: aluminium, arsenic, lead, cadmium, chromium, cobalt, nickel, mercury and zinc. For comparison, you will also receive the recommended reference values, which your values should not exceed. In the case of copper and zinc, there is also a recommended minimum value, as the body needs these two metals.

For some heavy metals, it is enough to measure their concentration in your urine. Others are measured per gramme of creatinine in your urine – so, the measurement takes into account the concentration of your urine so that it does not affect the results.

The measurements you receive give you a great indication of your current exposure to heavy metals.

How long does the analysis take in the laboratory?

Once your sample has arrived at the laboratory, it will be analyzed there by specialists. How long the analysis takes depends on the exact measuring method and the processes in the laboratory.

If the sample is sent on the correct days (Sunday to Tuesday), this makes it easier for the laboratory to adhere to the times.

For the Heavy Metal Test, the laboratory analysis is usually completed within 7 working days after the sample is received in the laboratory.  

Which recommendations will I receive?

If the Heavy Metal Test reveals excessive exposure to heavy metals, you should visit your doctor as soon as possible. Doctors can advise you and, in severe cases, remove the metals with chelation treatment.

If the levels of certain heavy metals are slightly higher than normal, you should do anything you can to avoid the source of the pollutants. This then means, for example, avoiding fish if a lot of mercury was found in your body, paying attention to how much rice you eat if you had high arsenic levels, or skipping zinc supplements if your zinc levels were significantly higher than normal.

What are heavy metals?

Heavy metals are metals that can be toxic to humans in larger quantities. These include, above all, lead, cadmium, chromium, cobalt, nickel, mercury and zinc.

When talking about heavy metals, two other metals are often mentioned that are not heavy metals but can also be harmful: aluminium, which is a light metal, and arsenic, which is a semimetal.

Heavy metals enter the air we breathe mainly through emissions from factories and road traffic. From there, they settle in the air we breathe and also enter our food via soils and plants.

What are the symptoms of heavy metal poisoning?

In your own home, for example, broken residues of old mercury thermometers and ceramics with a lead glaze can lead to chronic heavy metal exposure. In the long run, such increased heavy metal exposure could also affect your health.

Symptoms of chronic heavy metal poisoning depend on the way heavy metals enter the body. Mostly, this happens via your skin, respiratory tract or gastrointestinal tract. Possible symptoms are:

Diarrhoea, vomiting and nausea

Stomach pain, headaches and aching limbs

Sleeping problems and a feeling of weakness

Skin changes

Symptoms of paralysis

Acute heavy metal poisoning is rare today. Cases are mostly the result of accidents, especially in the metal industry.

How do I reduce exposure to heavy metals?

In order to ingest as few toxic heavy metals as possible in your everyday life, you should be aware of the typical sources of pollutants.

There are a number of foods that are often contaminated with heavy metals:

• Arsenic in rice and rice products
• Mercury in large saltwater fish
• Lead in leafy vegetables and game
• Cadmium in wild mushrooms and beef or pork liver

Other sources of pollutants in your daily life include:

• Lead pipes in old buildings
• Lead-glazed ceramics (often bought while travelling)
• Broken old mercury thermometers
• Old home remedy ointments and contaminated Ayurvedic supplements from Asia

When and how do you get rid of heavy metals in your body?

In cases of severe heavy metal poisoning, doctors use chelation treatment. They administer chelate complexes; these substances bind heavy metals in your body. Your body can then excrete the metal and chelate compound relatively easily. However, important trace element such as zinc is also flushed out of the body. Doctors therefore monitor these mineral levels and prescribe dietary supplements, if necessary.

If there is only mild poisoning or chronic heavy metal exposure, treatment usually involves avoiding the sources of the pollutants, so that your body can gradually eliminate the metals itself. In some cases, your body needs many years to get rid of heavy metals once they have been stored there – this can only succeed if more pollutants do not enter your body and accumulate there on a regular basis.

Who should NOT take the Heavy Metal Test?

The Heavy Metal Test is not or only partially suitable for certain groups of people:

People with infectious diseases, like hepatitis and HIV, may not use the Heavy Metal Test.

People with haemophilia should not take the test.

Pregnant and breastfeeding women should only take the Heavy Metal Test under medical supervision. The given reference ranges and recommendations do not apply to people in this group; consult your medical professional for advice concerning your test results.

The Heavy Metal Test is not intended for children under 18 years of age.

The test is not intended for diagnosing illnesses or disease. For example, if you suffer from depression or are in extreme physical pain, consult a doctor.

Why are children under 18 not allowed to take the test?

Our tests are not suitable for underage children and adolescents under the age of 18. Under 18s cannot activate the tests online and therefore cannot receive a test result. We ask that you do not administer the tests to your children either.

Children and adolescents need much closer supervision and counselling regarding medical tests and their interpretation. Testing with lancets and chemicals is not without risk and would need to be closely supervised by guardians. In addition, the reference values we give are always based on adult data. In the case of children, the risk of misinterpreting the results would be very high.

We want to fulfil our responsibility as a provider of medical products and ensure that children and adolescents are not unsettled by measurement results that are difficult for them to interpret. Since we cannot control whether the minors' legal guardians actually consent to the test being carried out and supervise them, we exclude tests for under 18s altogether.

If you are under 18 and have purchased a test, please contact our customer support.

Why does it take up to a week for the sample to reach the lab?

Please bear in mind that your results will not be analyzed in the UK but in Germany. For that reason, it can take up to a week for the sample to arrive at the lab. This does not affect the stability of the samples, as the method we are using is optimized for long transports.

Initially, your sample is sent to our collection center in the UK. From there, it is shipped to our central sample sorting facility in Germany, which then distributes samples to our partner laboratories. Once your sample is analyzed there, you will receive a notification and can access your result online.

Please check your mailbox regularly. We will notify you as soon as your sample is sent, arrives, or is analyzed.
