It will depend on what your company is looking for. The half-life is between 9-20 hours. Therefore you have had 1.75 half-lives using the 20 hour half-life value. The typical blood or plasma concentrations are usually in a range of 10-100 μg/L in persons receiving the drug therapeutically, i.e. you have a prescription. So as long as this is a general drug test vs. a critical position drug test you probably will not have a problem. Most people who take this drug under a prescription are taking it every 4-6 hours.
