Last Updated On: January 2020

Every year across the country, people try and fail to use urine that is not their own during drug tests.

Although people are caught in a lot of different ways, the most common is the failure to have the pee at the correct temperature.

Keeping the urine you want to use at a constant warm temperature that replicates the human body is a really tough task.

We humans are great at keeping things hot or cold, but natural body temp or warmth falls into that awkward in-between area that is very difficult to maintain.

For this reason, many people have turned to using synthetic piss kits, which are much easier to work with when it comes to regulating normal pee temperature. Real pee must be kept refrigerated so it is fresh and you then have the challenge of reheating it properly.

Artificial pee is stable at room temperature though, making it much easier to bring up to our normal body heat or warmth. This means that fake urine is actually easier to store than real human pee. 

I know it may seem crazy to be thinking about the temperature of urine, but honestly, this small detail can be what stands between you and getting through a urine drug test.

Right now, I am going to lay it all out for you and explain in detail why urine temperature during your drug test matters. And, also fill you in on how to best regulate the heat of pee for a drug screening.

Let's get into the juicy details.

Why Do You Need to Keep Pee Warm for a Drug Test?

Urine tests are probably the most popular way for employers to screen their employees for drugs. You might be surprised to know that there are not too many ways that the testing staff can guarantee you have not used fake piss, one of them is temperature.

What they do is measure the temperature of your sample right out of the gates.

Any sample that has a temperature that is either too low or too high will immediately raise a red flag.

That means it is automatically rejected. And yes, that pretty much means that you're losing your job. 

They know that there's only a couple of minutes from the time that the urine leaves the body and into the cup, and to the tester. That means that the temperature of your pee should be very close to what it is inside the body. If it is off by quite a bit then you're definitely getting the attention that you do not want. 

There are so many people that simply don’t understand this and every day, people are caught when they didn’t have to be. All because they didn't pay attention to the temperature of the sample that they have given. It's such a small thing but it plays a huge part in your success. 


If you need to put in a fake sample, the temperature needs to be your number-one consideration.

What is the Right Temperature for Urine?

Let's do it. Let's talk about the question that you guys have all been waiting for.  

What exactly is the temperature of urine when it leaves the body? Does it need to be exactly around that temperature when you pass the sample? 

And, what is the optimal temperature of synthetic pee for it to be seen as "real" by laboratory testings and most urinalysis exams?

The Answer: The temperature should be in the range of 94°F to 96°F (about 35 °C). It's the temperature of real human urine when it leaves the body so if the artificial piss you're using is not within those temperature when you submit it then it will be flagged as "fake pee".

What Tools do you Need?

There is a lot of misleading information out there when it comes to keeping pee warm for urinalysis or lab tests, but in reality, you probably have all the tools you need already at home.

First of all, you need a microwave, which just about everyone has. If you don't, it's time to live in the 20th century, buddy!

Of course, you will also need a container for the pee and some way to strap it to your body in a natural and unobtrusive manner, and last of all, some kind of temperature strips or thermometer. Now let’s have a look at how you can bring this all together to keep your urine sample warm.

One thing that we've found that fits all of these are called urination devices. 

The most reliable urination devices that we've tested are the Monkey Dong which is for men, and for females it's the Monkey Whizz. Both are natural looking strap-ons and devices that will help you mask what you are about to do in a way that it will never be detected. 

Also, you will need some temperature strips or thermometer. But if you're using the Monkey Dong or Monkey Whizz, you won't have to worry about that because they already have a built in system. Cool, right?

A Quick Guide to Regulating Urine Temperature:

  1. Take your clean sample out of the fridge and place it in the microwave. You need to store it in the fridge so that it stays fresh, but now we have the challenge of bringing it up to the urine test temperature range (around 90-100⁰F) and keeping it there.
  2. Microwave the pee for no more than 10 seconds at a time – even use a low setting on the microwave if you have that option. You may need to zap it more than once, but the last thing we want is to heat it too much. Going way above natural body temperature will ruin the sample. If you are using a synthetic pee, then your task will be a lot easier as it begins at room temperature. Test in between rounds in the microwave with the thermometer and stop when you get into the right range.
  3. Now you need to move quickly, as your urine will be cooling by the second. You need to strap it in nice and tight against your body so that your natural heat can help to maintain the temperature of the sample.

Covering it with some kind of cloth can also help to insulate things.

Note: This solution is not perfect, and you will not want to rely on just this to keep urine warm and fresh for hours on end.

You will need to time it so that you go through this process as close to the time of the test as possible. If you use synthetic urine like Quick Fix, it will stay warm for longer than natural urine as it includes both heating elements and pads that will help you keep it warm throughout the entire time. 

Best Solutions to Keeping your Pee Warm

An alternative solution that many people have started using is heat pads or hand warmers. You have probably seen these nifty little handheld devices that are activated with a bit of a shake that causes a chemical reaction.

These heating pads are almost the perfect way to maintain your urine sample at the right temperature.

If you have access to one of these hand warmers, you can follow the exact steps as shown above, but strap the hand warmer to you along with the sample, which will give you a longer period of time at the right temperature. Heating urine for a lab test can be tricky so make sure you follow every step.
