Oral fluid test or Saliva test analyzes for the parent drugs and its metabolites through the use of a saliva sample. An absorbent collection method using swab sticks is placed inside the mouth where fluids and saliva are collected, then screened for abuse drug use.
What makes saliva or oral drug test more accurate?
Both urine and oral drug test are considered accurate, though oral drug test has the following advantages over urine drug test, in the aspect of:
- Earlier detection time that makes oral drug test more sought after since it can give earlier results. The window of detection is usually within 24-48 hours on the average.
- Oral fluid test also detects drugs in the fluids at 30 to 50 minutes after ingestion. This is excellent in cases of post-accident requirements to prove if the individuals who are directly involved are not under the influence of drugs or alcohol while driving. For urine it takes 24-72 hours to detect usage.
- Based on a review of the data gathered from over 4.5 million tests done using oral method, it showed positive ratings compared to laboratory urine testing.
- Oral samples can even be retained for a period of 1 year.
- The collection of sample is done by the donor with direct visual supervision of a laboratory trained technician to prevent contamination. Also with the guidance, it is assured that the sample collection follows the standard. These are taken inside the mouth on the inner part of the cheek, then in the gums. It cannot be challenged because the donor is the one collecting the sample while in direct supervision.
- Oral drug testing cannot be adulterated. Any attempts of introducing other substances to the sample can be observed. In the case of dilution tactics done for urine samples, this could not be done with oral fluid testing.
Moreover, the result of an oral drug test is supported in numerous court cases either in family courts or in the criminal justice.
