How do labs detect synthetic urine?

Urinalysis Drug Tests

Urine testing is the cheapest and fastest way to detect drug use. Unfortunately, synthetic urine is more widely used to attempt to cheat these drug tests. That’s why it is very important to use AABB labs that use specimen validity testing to ensure that untampered human urine is collected and tested for accurate results.


A sample of urine provides a drug history from the last two to three days for most drugs, and an even longer period for marijuana. The widespread use of recreational marijuana has contributed to an increase in synthetic or animal urine in order to pass drug tests. However, synthetic urine lacks normal creatine values and PH levels, which make is easy to detect as fake or inhuman. Amino acids and hormones also differentiate in humans and animals which make detection possible at our labs.


Synthetic urine has been around since the 80’s when drug testing federal employees became mandatory. Since then, the science behind fake urine has greatly improved, which is why our team at ReliaLab stays up to date on the ever changing components of synthetic urine and keep our protocols and duty of care top notch.


Keep in mind:
While synthetic urine can be caught, substituting someone else’s clean urine is a possibility that is hard to catch. Since urine collections are unsupervised, it is recommended to request a supervised observed collection for drug testing such as hair, blood or oral fluids where the probability of substitution is extremely small.


Bottom line is detecting synthetic urine is a job for professionals, so call 615-332-8838 to schedule a drug test with ReliaLab to make sure you’re getting the most accurate results. ReliaLab testing has 24-72 hour turn around for negative urine testing so you can feel at ease with fast results.
