Urine and saliva drug test kits can provide accurate results, especially when used correctly and in line with the manufacturer’s guidelines.

Urine drug test kits can be more accurate than saliva testing because they generally have a longer detection window for certain substances compared to saliva testing.

However, both drug testing methods are accurate depending on the intended detection window the tester would like to know.

Hair follicle testing and blood testing are other forms of screening drugs. These methods are usually more tedious and expensive compared to the convenience of saliva and urine testing and tend to have a longer detection window.

These methods are usually conducted in professional laboratories and are considered more invasive than their urine and saliva counterparts.

False results can happen in drug test kits and can be caused by a number of different factors, including the quality of the test kit, specimen collection and handling, external contaminations, and individual factors such as age, gender, diet or any underlying health condition.

If you suspect that your drug test kit is producing a false result, a confirmatory test will need to be administered to ensure the right results.

Drugs can be detected using saliva drug test kits usually up to 48 hours after the last use, while urine test kits can detect drug metabolites up to six weeks after the last use depending on a number of factors such as the type of drug, frequency of use and individual factors like metabolic rate, age, gender, hydration and more.
