Allergen, Individual-Occupational Isocynate Mdi Test

Isocynate is used primarily as starting materials in a variety of manufacturing processes, including the production of plastics, polyurethane, foams and electrical wire insulation. They are also common components of paints and other durable and protective finishes, adhesives, elastomers in automobile bumpers, printing rolls and coated fabrics. Exposure to these during work is very common in these specific industries, and it can occur at any stage from the initial manufacturer of the isocyanates to their final use in other production processes. It can cause chemical bronchitis, laryngitis and chest pain, and severe asthma.

This test, unlike other common blood tests, does not require fasting. No other special preparation is required, and it is advisable for the test taker to inform their doctor or test provider about any medical conditions or allergies otherwise existing. The doctor must also be informed of any other medications, especially for respiratory problems, that the test taker is taking, pursuant to which the doctor will give specific instructions. It is advisable that the test taker wears a shirt or t-shirt which exposes the forearm or is loose enough to roll up, as the test site is the forearm.

This test will be conducted to see if the person had been exposed to such a level of isocynates that he has developed conditions like chronic chemical bronchitis, laryngitis, throat irritation, chest pain and tightness. If the test results are positive, the person will have to begin treatment to prevent conditions like asthma from worsening. It will also require the person to discontinue exposure to the chemical, and he may stand to receive compensation from his employer given other conditions are satisfied.

The general test used uniformly all over the world is the skin prick test. Here, a needle is pricked on the forearm of the person with a small amount of the allergen. The test is done is specialised allergy testing centres, full service testing centres or at a clinic or hospital. A part of the skin on your arm is chosen as the site, which is cleaned by rubbing alcohol. After this, the needle is injected. The skin is observed for a period of time to see if it shows any reaction to the allergen. A blood test may also be conducted to determine the presence of allergen in the blood, but this is used only in case that the skin prick tests are inconclusive.
