This test measures the amount of butanone (MEK) in the urine that can be absorbed by inhalation or skin absorption of either the liquid solvent or solvent vapours.
Butanone is also known as methyl ethyl ketone (MEK). This colourless liquid is produced industrially on a large scale, and also occurs in trace amounts in nature. It is soluble in water and is commonly used as an industrial solvent.
Butanone is a constituent of tobacco smoke. It is an irritant, causing irritation to the eyes and nose of humans. Serious health effects in animals have been seen at very high levels. These included skeletal birth defects and low birth weight in mice when they inhaled it at the highest dose tested (3000 ppm for 7 hours/day). There is some evidence that butanone can potentiate the toxicity of other solvents.
Gas Chromatography (GC)
Mostly used in occupational health for toxic exposure testing.
Normally urine does not contain any Butanone. If there is a positive result then action should be taken.
The laboratory test results are NOT to be interpreted as results of a "stand-alone" test. The test results have to be interpreted after correlating with suitable clinical findings and additional supplemental tests/information. Your healthcare providers will explain the meaning of your tests results, based on the overall clinical scenario.
Certain medications that you may be currently taking may influence the outcome of the test. Hence, it is important to inform your healthcare provider of the complete list of medications (including any herbal supplements) you are currently taking. This will help the healthcare provider interpret your test results more accurately and avoid unnecessary chances of a misdiagnosis.
