There are many tests which are available to ascertain whether or not you are being poisoned by the mercury in your amalgam fillings, or even by any other metal in your fillings or crowns. Not all tests which your GP may send you for will give a "positive" result even if you are loaded with mercury. I myself, had a blood test which came back normal. This is because mercury does not always circulate in the blood stream, it sticks to the tissues within the body. It is the same with a urine test, mercury will only show up in the urine if you are given a chelating agent beforehand. The mercury bonds to the chelating agent and therefore shows up in the urine. But you will not be given that type of urine test by a hospital which your NHS GP may send you to. A Metal Allergy Patch Test proved positive with me.


This is a very simple test. I had it done at the Royal London Dental Hospital, Whitechapel, London, E1 by a Professor Martin Thornhill, who I understand is no longer at that hospital but is in the U.S.A. I don't, however, know if anyone else has taken his place. I had to wait quite a number of months for Prof. Thornhill to arrive at the hospital. But I'm sure there MUST be another NHS hospital somewhere that will also do such tests. I was originally sent to Eastman's Dental Hospital, Grays Inn Road, WC2 but after waiting 6 months for an appointment I saw a Consultant who told me that they didn't do any tests at all for mercury toxicity as mercury was COMPLETELY SAFE!!

The test at the Royal London was a very simple test. A very large patch was placed on my arm after tiny amounts of mercury, palladium, copper, zinc and other metals as well as white composite material had been placed in minute "dishes" on the patch. That was on the Monday morning. I had to return on the Friday morning. During the days I had the patch on I was very unwell to say the least. Many of my symptoms appeared but were magnified many times but apart from that there was no itching which I thought would happen.

When I returned to the hospital I was taken into a room. A nurse told me that although I'd not had any itching, if I did have a problem with mercury or any of the other metals then I would have itching once the patch was removed. As soon as she pulled the patch off my arm began to itch and sting like crazy and I could see huge red bumps appearing on my arm. Apparently the air hitting the skin sets the itching off that's why I had no itching all week. It was obvious straight away that I did have a problem with mercury and some of the other metals as those bumps were very raised, red and itchy compared with some of the others.  It was 3 months before all sign of the bumps disappeared completely

The MELISA® Test is very reliable. It was developed by Professor Vera Stejskal.  It is a scientifically-proven blood test which can diagnose metal allergy. The following information was sent to me by Professor Stejskal's daughter Linda.

A MELISA® test puts a range of metals into contact with the white blood cells in your bloodstream and from there it measures the reaction. It can also measure the reaction of Thimerosal which is a mercury based preservative used in vaccinations.

The way it works is:

As well as the memory in our brain, we also have a memory in our immune system. The white blood cells we have in our bloodstream are our memory cells and they circulate in the blood. Any encounters with an antigen (a substance such as a toxin or bacteria which stimulates the production of antibodies) are remembered by the memory cells. When the white blood cells come up against antigens they will try to destroy what they see as a foreign invader. This is what signals an allergy. This happens in a blood sample as well as in the body.

Patients who have a metal allergy will have memory cells formed from when they were originally exposed to the metal so in any blood sample there will be memory cells. During the test the lymphocytes in the blood grow, giving a positive test result.

The MELISA® test can diagnose allergy to around 40 different metals (including 4 different types of mercury: inorganic, methyl, ethyl and phenyl) and many chemicals incuding formaldehyde. It can also diagnose Borrelia (Lyme Disease) and Candida.

The MELISA® test is named after this procedure:

Memory Lymphocyte Immuno Stimulation Assay.

The MELISA® tests' home is The MELISA® MEDICA FOUNDATION in Stockholm, Sweden. The Foundation dedicates itself to the science of metal allergy and its use in treating "incurable" diseases such as Chronic Fatigue Syndrome (ME), Multiple Sclerosis and other autoimmune and allergic diseases. Research has proven that, in the majority of CFS (ME) patients, hypersensitivity to metals is the main cause. Removal and avoidance of the metals leads to improved health. Some MS patients have found that by avoiding the offending metal or removing it (amalgam fillings), which MELISA® diagnosed them to reacting to they have fully recovered from their 'MS'.

Prof. Vera Stejskal runs the Foundation. The Foundation's directors include, Romuald Hudecek, one of the world's leading experts in amalgam removal and metal-free dentistry, as well as Birgitta Brunes, GP who has herself recovered from Multiple Sclerosis and has written about her experience.

Prof. Stejskal was, at one time, head of Immunotoxicology at Astra Pharmaceuticals (known as AstraZeneca), where she played a key role developing Losec, a multi-billion-dollar stomach ulcer drug and is now Associated Professor of Immunology at Stockholm University. She has written numerous articles on metal allergy and gives lectures frequently. She has also been an advisor to the World Health Organisation. In 2002 she was called as an expert witness to a US Congressional Committee looking into the safety of vaccines and thimerosal allergy.


The Cost of a MELISA® Test

Currently, (March 2005), the price of a test is £20 per metal, £200 for a 10 metal panel and £300 for a 20 metal panel (for patients with amalgam or gold fillings.)


A doctor or dentist can refer you for a MELISA® test. A sample of your blood is taken and shipped to the nearest MELISA® lab. There is a MELISA® clinic in London at:

Integrated Health Solutions
31 Queen Anne Street
London W1G 9HX

Phone: 020 7224 6777




There is a test called a Lymphocyte Sensitivity Test which you can have to find out if mercury or other metals are causing you a health problems. Biolab Medical Unit (UK) is a medical laboratory that specialises in Nutritional and Environmental Medicine. PLEASE DO NOT CONFUSE THIS WITH THE MELISSA® TEST. ONLY MELISSA CAN DO A MELISSA TEST!


The way it works is:

Lymphocytes are separated from a blood sample and incubated with heat-activated microscopic glass beads. The adhering lymphocytes are then visualised by video-phase contrast microscopy. Microcapillary electrodes are used to measure the resting potential of a series of lymphocytes and minute quantities of the test substance are directly applied to the cell membrane. The change in resting potential is recorded for a sufficient number of cells to give a reliable indication of the degree of sensitivity. For each test substance, we report a numerical value derived from the average change in resting potential. Values below 100 are considered to be normal. Values up to 1000 are seen in a marked sensitivity.

The Cost:

A Mercury Sensitivity Test costs £50 but you can have other elements tested at the same time for £10 for each additional element. There is also a Metals Sensitivity Test which costs £97 and this tests for mercury, nickel, silver, cadmium, copper, lead and gold.

Not everyone who has a problem with mercury will get a positive test and if you really do suspect you are suffering mercury toxicity it is a good idea to have a Kelmer test soon afterwards.  A Kelmer test is a urine test which is performed before and after you take a chelating agent so that the mercury has something to stick to and can be released from the body via the urine. It checks the mercury and creatinine levels in the body. A Kelmer test costs £40.

You can find Biolab at the corner of Weymouth Street and Hallam Street (5 minutes from Great Portland Street and Regent's Park stations and 10 minutes walk from Oxford Circus.

Although Biolab is a private unit, if your doctor or consultant agrees to pay the bill they will do the tests for you.

The test can be done by post, but samples must arrive at Biolab within 24 hours.

You can get more information by contacting Dr. Mark Howard at Biolab on 020 7636 5959 or by email to



A test for metal toxicity can also be done by using a sample of your hair. This can be done by post and is arranged by Great Smokies Laboratory in the USA. They have been doing tests for over 20 years and are reliable. The test shows the degree of toxicity in 12 elements including mercury also 15 essential nutrients.

This test has to be arranged by a practitioner of some kind. Pam Clewley, a fellow sufferer, has a diploma in Nutrition and can arrange this for you. The cost is £45 and £1 for postage.
