13. What does a “positive” urine drug test result on an immunoassay actually mean? the patient was compliant and took the prescribed drug as directed. the patient was only partially compliant and just took 1 dose prior to collection. the patient could have directly spiked/added the drug into the urine sample after collection. the patient took another medication that cross-reacted with the immunoassay causing a false-positive result. False-positive results are one of the limitations of using an immunoassay. 13 IMMC Drug Screening

14. What does a “negative” urine drug test result on an immunoassay really mean? the patient is not compliant with their prescribed medication the patient was partially compliant and maybe missed a few doses, or took less medication. the patient is well hydrated and the urine is dilute or possibly adulterated. the wrong test might have been ordered and the test may not cross-react with the patient’s medications. the drug may actually be present, but it is below the cutoff or detection limit of the assay leading to a false-negative result. False-negative results can happen as easily as a false-positive result with immunoassays. Therefore, it is important to look at the assay cutoff or detection limit when interpreting test results. 14 IMMC Drug Screening

15. Other information of value timing between when the patient last took their medication and when the urine sample was collected. Specimen validity testing can also be used to help determine the integrity and quality of the patient’s sample. 15 IMMC Drug Screening
