The biological content of oral fluid is directly relational to blood plasma.
Therefore, if we detect drug metabolite in oral fluid, those metabolites are still present in the blood stream, indicating that the substance has recently been active in the body; so oral fluid is the choice matrix for ‘for-cause’ testing, but can also be used for random and pre-employment situations where you need to check someone is safe to enter site, or a hazardous environment.
Screening using our sophisticated range of oral fluid tests is less invasive than urine screening, and doesn't require the same preparation.
Oral fluid is immune to attempts of adulteration, substitution or dilution of the sample; so as long as our best practice methods are adopted, oral fluid screening represents a straight forward and reliable means of screening for 'impairment' or recent use of drugs of abuse.
If a test shows non-negative at screening stage, an oral fluid laboratory confirmation service is available to identify the exact metabolite or analyte present and give expert opinion for any action that needs to be taken. Simply take another two sets of samples using the oral fluid collection kit for laboratory analysis.
