Does Guardian Life Insurance Drug Test? 
Yes , all companies when using paramedical exams do some drug testing as part of the chemical analysis in the underwriting process . Some drugs will effect certain levels of function within say kidney function that will show up by pushing the level higher . Alcohol for example , a legal form of a `` drug '' if consumed too close to an exam will raise blood sugars , alter the kidney function numbers and a few other numbers like those involving the liver . That is why it is never a good idea to consume significant amounts of alcohol the night before a blood/urine test . It will skew the results . Then it is up to the individual to get a second test , at their expense to show the first test was off .
