What do I do if I fail by getting a false positive result?

If you get a positive result you need to immediately request a new test or even request a different type of drug test. Some companies may be sympathetic and will allow you to retest, particularly if you have a reasonable story and are sincere. Present prescriptions or medications you might be taking and do your research s to what might have caused the false positive drug test. Always emphasize your innocence and the fact you do not know why you have failed. Be honest, concerned and DO NOT mention the possibility of a false positive drug test. You must then start your research on why you have failed and make the commitment to see your innocence to the end. Learn as much as you can about the topic, there is some good information out there on this subject and we are currently researching to provide a more in-depth view into what can cause false positive results. Your confidence and understanding can make the difference. If you are given a second chance to take the drug test you might want to consider the following factors and actions. This is the time for action if you are to get through this. If you understand these factors  you will be ahead of most of the people giving the drug tests. This is the edge you could really use.

  • Let the tester know you are not guilty and ask to be tested again. It would not be fair for them to re-test you right then and there and expect a different result. You need time to identify why you failed.
  • Write down all medications and prescriptions you have been taking over the past few months, keep the packages and makes sure to provide this information to the testers when you take your re-test.
  • Make plans for a new test and start a detoxification process straight away. Do this whether you get the re-test or not. It is better to be prepared for the re-test and not get it then to get the next test and not be prepared. Being prepared is always a good strategy.
  • Identify and obtain the detoxification product appropriate for the test you will face.
  • Watch the food you eat. High fat foods, greasy foods (particularly butters, cream sauces, and fried foods) and junk foods slow the detoxification process.
  • Avoid alcoholic beverages, smoking or any unnecessary medications or vitamins.
  • Stay out of toxic environments.
  • Consume regular water each day, a litre or two is a good amount. Drink and sip all day and not all at once.
  • Exercise up to the day of your retest, but not on the day of your drug test.
