Health: 10 Mistakes that Most People Make

How to Maintain the Right Warmth of Synthetic Urine

As much as 95% of employers prefer urinalysis as a drug testing method, and this specific statistic may have increased the popularity of synthetic urine through the years. However, to use the product successfully, it is crucial to use it properly.

Importance of Keeping Synthetic Urine Warm

With initial drug screening normally excluding a validity test for samples, the testing staff may simply check the temperature of the urine, ensuring it has not been substituted. Human urine is naturally warm, so it follows that your synthetic urine sample is warm too; otherwise, testing staff will think it’s fake and decline it. Of course, getting caught also spells trouble with the person or organization that required the testing, not to mention with the facility itself.

Normal Human Urine Temperature

Human urine’s normal temperature can be anywhere from 94F to 96F. The staff usually records the temperature of a drug test sample within 4 minutes of receiving it, knowing that ambient temperature can cause changes in it. The acceptable range is between 90F to 100F; if the sample falls outside of this, it is automatically considered suspicious.

Warming Synthetic Urine

These are the most common methods of heating synthetic urine:


Microwaving synthetic urine is the easiest method of increasing its temperature by far. Just put the container inside a microwave and let it stay for around 10 seconds. A temperature strip comes in handy when it comes to checking the usability of the sample. Don’t leave it in for longer as excessive heat can destroy it. The properties of natural human urine can no longer be restored even as the sample’s temperature decreases.

Hand Warmers

Hand warmers are very handy and available anytime, and they’re a more practical alternative to the microwave. Just put the liquid in a small container and tape the hand warmer around it. Not all hand warmers work the way however. Buy one that maintains heat in the 90F to 100F range for as long as necessary.

Your Body

You may not have to look far – your own body can be your most effective synthetic urine warmer. Put the sample in a sealed plastic bag and tuck it in your inner thighs or even inside your underwear. Another good spot is inside your bra, if you’re a woman, or under your armpits.

Practice Makes Perfect

Finally, before actually showing up at a testing facility with your synthetic urine, don’t forget to practice, practice, practice. You should know what you have to do and how you can do it best so as not to appear suspicious. The more your practice, the more confident you will be during the testing.
