Does the drug test quantify the concentration of drugs present in the oral fluids sample?
A positive drug test result does not indicate the concentration of drug in the sample. All positive results are presumptive and should be confirmed by an alternate method (e.g. GC/MS or GC/MS/MS). Negative results may not necessarily indicate a drug-free sample. Drug may be present in the sample below the cutoff level of the assay. 3. DRUG TEST PROCEDURE Q: If the donor has a dry mouth, can they have a drink of water? A: Yes. A drink of water may be given to the donor. It is best to wait for about 10 minutes after the drink before attempting another collection.
