Osumex Heavy Metals Test General Kit


Notify me when back in stock

The Heavy Metals Test - General (HMTG) kit was developed for Osumex as a simple to use at home test kit for a preliminary determination of the presence of an identified range of heavy metals.

These heavy metals comprise: Cadmium, Cobalt, Copper, Lead, Manganese, Mercury, Nickel and Zinc.

The HMTG kit utilises chemical reagents to show the presence of heavy metals. The free metal ions of the heavy metals, if present, stimulate a colour change to the reagents. Accordingly, the more metal ions are present, the stronger the resultant colour change.

The chemicals used in the reagents are bio-degradable and do not further contaminate the environment, especially if disposed off properly after use. The reagents contain oils which pose no health risk to the user if contact is made. However, where contact is made to the eyes or inside the mouth the user is encouraged to consult his or her physician as soon as possible. It is recommended that the used solutions be flushed down the toilet as a good disposal guide.

The HMTG kit is suitable for testing any liquid medium such as saliva, urine, breast milk or tap water, provided that the liquid is fairly clear preferably without suspended solids or sediments. Straining the liquid to be tested would be a good idea to achieve a clear colour change and for an easier reading. Solids such as food, supplements, raw fish, etc. can be tested after it has been soaked in distilled water for 24 hours or treated. 

For a more accurate result, the pH of the sample solution to be tested should be at least 5.0

Heavy metal toxicity represents an uncommon, yet clinically significant, medical condition. If unrecognised or inappropriately treated, heavy metal toxicity can result in significant morbidity and mortality. The most common heavy metals implicated in acute and/or chronic conditions include lead, arsenic, and mercury.

The Osumex Heavy Metals Test kit can detect heavy metals contamination especially inorganic heavy metals to ppb or ppm. It is an easy to use at home kit and gives result in minutes that is easy to read. The level of heavy metals present is measured by comparing to a colour chart.

To test the substances which are not in solution, preparation can be made to convert them into solution for testing, this includes dust, dirt, paint, rice, milk, food, dishes and glasses.

Sensitivity: presence/absence* (with a colour indication of the type of metal that may be included)

*Presence is shown for levels above 5ppm (mg/l) for cadmium, cobalt, copper, lead, mercury, nickel and zinc. For manganese a presence is shown when level is above 1ppm (mg/l).

Kit Contains:

  • Colour chart and instruction sheet
  • 1 Test tube with special white cap
  • 1 Vial containing clear test solution
  • 1 Pipette/dropper

Osumex's Heavy Metals Test kits test the presence of heavy metal ions to a high degree of accuracy (in parts per billion {ppb} and million {ppm} in the body and of a wide range of materials in the environment.

The Heavy Metals test kits are designed especially to detect the presence of toxic heavy metals in the body. They can also be used to detect heavy metals in most clear liquid medium. It is important to check the presence of heavy metals because they are the main cause of excessive free radical activity, which can cause damage to the healthy state of the body including depleting the body's immune system. The Heavy Metals Test kit can also be used to confirm the presence of metals/minerals in food such as iron in rice, etc.

Toxic heavy metals can cause the following health problems  (
  • Long term exposure to cadmium is associated with renal dysfunction. Cadmium is bio-persistent and once absorbed remains resident for many years. High exposure can lead to obstructive lung diseases and has been linked to lung cancer. Cadmium may also cause bone defects in humans and animals. The average daily intake for humans is estimated as 0.15g from air and 1g from water;
  • Low exposure to chromium can irritate the skin and cause ulceration. Long term exposure can cause kidney and liver damage. It can also cause damage to circulatory and nerve tissues;
  • High doses of copper can cause anaemia, liver and kidney damage, and stomach and intestinal irritation. People with Wilson's disease are at greater risk for health effects from overexposure to copper;
  • Exposure to lead can lead to a wide range of biological defects in human depending on duration and level of exposure. The developing foetus and infants are far more sensitive than adults. High exposure can cause problems in the synthesis of haemoglobins, damage to the kidneys, gastrointestinal tract, joints, reproductive system and the nervous system. Studies have suggested that exposure to lead can cause up to a loss of 2 IQ points;
  • Inorganic mercury poisoning is associated with tremors, gingivitis and/or minor physiological changes together with spontaneous abortion and congenital malformation. Monomethylmercury causes damage to the brain and the central nervous system while foetal and post-natal exposure have given rise to abortion, congenital malformation and development changes in young children;
  • Excessive amounts of nickel can be mildly toxic. Long term exposure can cause decreased body weight, heart and liver damage and skin irritation;
  • Exposure to high levels of arsenic can cause death. All types of arsenic exposure can cause kidney and liver damage and in the most severe exposure there is erythrocyte haemolysis;
  • Manganese is known to block calcium channels and with chronic exposure results in CNS dopamine depletion. This duplicates almost all of the symptomology of Parkinson's Disease.
  • Aluminium toxicity is associated with the development of bone disorders including fractures, osteopenia and osteomalacia.
