“How does a urine test differ from a saliva test?”
I have had both a urine and saliva test done recently. How do the 2 produce different results?

Oral fluid testing has the ability to detect resent drug use, whereas urine requires the drug to metabolize after consumed which can take up to 6 – 12 hours. Thank you.
Results may differ because urine is basically an excretory product of the body and it may never reflect normal concentrations of body constituents. Saliva and blood are amongst the body fluids and they may reflect the concentrations of these in a better manner.
