Synthetic urine is a laboratory developed chemical composition designed to mimic the composition, chemical properties, and appearance of real human urine. It is made with chemical compounds that mimic urea, creatinine, and uric acid in real human urine, plus other elements that include some mixture of ammonia, sulphates, phosphates, potassium, chlorides, and/or others. The actual mixtures vary from manufacturer to manufacturer. However, the synthetic urines are made to have the same pH and specific gravity as real human urine.

Source: Synthetic urine is mostly chemically manufactured. There is also a form of synthetic urine that is actually dehydrated real human urine.

Forms: Synthetic urine is sold is various forms. The most common form is as liquid. Other forms include gel, powder, and paste. Dehydrated urine is real human urine sold as powder form.

Detection Period: Some of the newest synthetic urine products look and smell like real human urine. However, one of the first detection periods is within the first four minutes the sample is provided. The normal temperature of real urine is 33-38 degrees Centigrade. A urine sample that is colder or warmer is likely not real urine or is not recently collected. Many of the synthetic urine kits today come with a heating pad, temperature gauge, and/or hand warmer. The employer may use an onsite product to test the sample for creatinine, nitrite, glutaraldehyde (usually present in urine masking agent products), pH, special gravity, oxidants, and pyridinium chlorochromate which can determine if the urine is real human urine. Drug or alcohol testing will also determine if these substances are present. This process uses an EMIT (Enzyme Multiplied Immunoassay Technique)

If the specimen is sent to an accredited testing laboratory for additional testing, a GC/MS (Gas Chromatography-Mass Spectrometry) is conducted. CMM Technnology has developed a proprietary process for detecting synthetic urine that tests for natural conditions and elements of real human urine.

Real urine has a pH range from 4.5 to 8, though some urines are a little more or less. Specific gravity is usually between 1.002 and 1.035, if the person being tested does not have kidney problems. Detecting synthetic urine also includes testing for creatinine levels, uric acid, nitrate, and urea. If any of the elements are not present, or

Legal Status: Purchasing synthetic urine is legal. Using it for purposes of deception during drug testing by the police or courts is not legal.

Other Information: Synthetic urine is not marketed as a substitute for human urine that makes it easier to pass a drug or alcohol test. Synthetic urine is made for legitimate purposes though purchased by people who want to cheat on drug and alcohol testing. It is used to calibrate urine testing equipment which is why it is made to mimic human urine as much as possible. Synthetic urine is also used in scientific research projects and clinical trials, and for testing products like baby diapers.
