Naloxone - Total (Conjugated/Unconjugated), Screen, Urine
Use
This test is used to screen for the presence of naloxone and its conjugated forms in urine samples. It is primarily employed when assessing patients for potential overdose or monitoring individuals in treatment programs. The test's ability to differentiate between conjugated and unconjugated forms of naloxone aids in the interpretation of recent drug use and helps clinicians make informed decisions regarding patient care.
Special Instructions
Must submit one specimen per order. Specimens cannot be shared between multiple orders. Ensure that the specimen is collected in a clean, plastic preservative-free container to avoid contamination that may affect test results.
Limitations
The test has limitations in detecting naloxone if the substance is present below the detection threshold. Cross-reactivity with other substances is possible, which may result in false positives or negatives. Environmental factors or improper specimen handling could impact the stability and accuracy of test results.
