What is a CLIA Waived Test?

As defined by CLIA, waived tests are categorized as “simple laboratory examinations and procedures that have an insignificant risk of an erroneous result.” The Food and Drug Administration (FDA) determines the criteria for tests being simple with a low risk of error and approves manufacturer’s applications for test system waiver.

About Drug Addiction

Drug addiction is a mental illness. Although initial drug use is voluntary, drugs of abuse have been shown to alter gene expression and brain circuitry, which in turn distress human behavior. Once the addiction grows, these brain changes interrupt an individual’s ability to make voluntary decisions, leading to compulsive drug craving, seeking and use.

The impact of addiction can be detrimental to one’s health. Cardiovascular disease, stroke, cancer, HIV/AIDS, hepatitis, and lung disease can all be affected by drug abuse. Some of these effects occur when drugs are used at high doses or after prolonged use, however, some may occur after just one use.

Displayed below is a drug use timetable of the most commonly abused drugs. The drug as well as the commercial and street names are listed. We’ve also provided information regarding how a drug is administered and how long the drug is detectable in urine and saliva.

Negative: Two colored lines appear adjacent to each other in the test window. This indicates that no drug above the cut-off level has been detected. The test line intensity may be any shade of pink and weaker or stronger than that of the control line. Since a negative sample may give a faint or incomplete line, any line in the “test result“ area, no matter how faint or even incomplete. indicates a negative result. All tests are independent of each other, it is not recommended to compare the results or color intensity of the test lines.

Positive: Only one colored line appears In the ”test valid” region. No test line appears in the “test result” region. A positive result for a specific analyte will have a line only in the “test valid” region of a test window.

No Results: If a line does not develop in the “test valid” region of a test window, no results should be interpreted for that test. Improper testing procedures, sample tampering or deterioration of reagents probably occurred. Adulteranls added to urine specimens may produce erroneous results regardless of the testing method of analysis. If adulteration is suspected.
