How Do I Keep Urine Warm At Body Temperature to Pass a Drug Test?

Keep Urine Warm

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, probably the most common is the failure to have the pee at the correct temperature.

Keeping the urine you want to use at a constant 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 falls into that awkward in between area that is very difficult to maintain and keep it at a normal average temperature.

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.

Artificial pee like Quick Fix is stable at room temperature though, making it much easier to bring up to body heat.

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 a pass in a pee test.

So what is the temperature of urine? It is in the range of 94°F to 96°F (about 35 °C).

Right now I am going to lay it all out for you and explain in detail why piss test temperature matters and fill you in on how to best regulate the heat of pee for a drug test. You will learn how to keep urine warm for a drug test.

Why do you Need to Keep your Pee Warm for a Drug test?

Urine tests are probably the most popular way for employers to screen employees for drugs. You may be surprised to know that there are not very many ways that the testing staff can guarantee you have not used substitute piss, except for temperature.

With the tools at their disposal, they simply cannot catch fake samples any other way.


What they do is measure the rate of decline in the temperature of the sample. Any sample where the temperature drops too quickly becomes suspect and is rejected as invalid. They know that pee that was in your bladder will be warmed throughout to your body temperature, while pee stored in a cup or other device is unlikely to be warmed so well.

There are so many people that simply don’t understand this and everyday people are caught out when they didn’t have to be, over just a few degrees in temperature.


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

What Tools do you Need?

There is a lot of misleading information out there when it comes to keeping pee warm for drug tests, but in reality you probably have all the tools you need already. First of all, you need a microwave, which just about everyone has.

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 bring this all together to keep your urine sample warm.


Step by Step Guide to Regulating Urine Temp:

  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 naturally body temperature will ruin the sample. If you are using a synthetic pee like Quick Fix, 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 we 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 this to keep urine warm for hours and hours.

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.

Alternative Solutions on How to Keep 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 drug test can be tricky so make sure you follow every step.


What’s the Best Way to keep Urine Warm for a Drug Test?

The absolute best way to keep a urine sample warm is to use a combination of synthetic pee, warming pads and your body’s own ambient temperature.
