Urine Specimen validity testing (SVT) The Test Before the Test
Specimen validity testing (SVT) is a critical component of urine drug screening programs. The process of collecting and testing urine samples for drugs of abuse can be susceptible to adulteration or substitution, making it challenging to ensure accurate test results. SVT is a mechanism used to assess the integrity of urine specimens and detect any attempts to tamper with or adulterate them.
SVT is a multifaceted process that includes various methods and techniques. Some of the primary methods used in SVT include testing for pH, creatinine, specific gravity, and temperature. These tests are used to assess the validity of the urine specimen by determining its composition and consistency. A urine sample that falls outside the expected ranges for any of these parameters may be indicative of tampering or adulteration.
Another common SVT method is the use of oxidizing agents, such as bleach or nitrite, which can be added to urine to mask the presence of drugs. These agents can cause a false negative result, indicating that the urine sample is drug-free, even if drugs are present. However, SVT can detect the presence of these oxidizing agents and other adulterants, allowing for accurate test results.
In addition to these methods, SVT also involves chain of custody procedures, including documentation and tracking of the sample from collection to testing. This ensures that the sample has not been tampered with or substituted during the collection process.
The use of SVT is essential for maintaining the integrity of urine drug screening programs. It provides a reliable mechanism for detecting attempts to alter or adulterate urine specimens and ensures accurate test results. SVT can help prevent false negatives or false positives, which can have significant consequences for individuals undergoing drug testing.
It is important to note that SVT is not foolproof and can be susceptible to manipulation by individuals attempting to cheat the system. However, the use of multiple SVT methods and stringent chain of custody procedures can help minimize the risk of tampering or substitution.
In conclusion, SVT is a critical component of urine drug screening programs. It involves various methods and techniques to assess the validity of urine specimens and detect attempts to tamper with or adulterate them. The use of SVT helps maintain the integrity of drug testing programs and ensures accurate test results.
Most times a collection center / lab will use a reagent stick validation before "accepting" the sample to be sent to the lab for drug screening. A quantitative validation test verifies its ph, color, specific gravity ( verifies dilution ) creatinine level and looks for nitrates or non urine AGENTS. This dentures wasting time testing bad synthetic or adulterated urine.

Ordered the urine trouble kit cuzz I will be taking a few test . don't think ill be observed but my friend turned me onto this , says no problem .
ReplyDeleteno you wont be observed , that requires court ordered issues but the urine trouble is a bit easier to dispense , carry , monitor etcetera , just practice with warm water and you will not have any nervous issues . used It myself in a number of labs .
