- The #1 reason why people fail drug tests when giving fake urine is down to the incorrect temperature range of the sample given.
- The average temperature of human urine should be at around 37 degrees Celsius or 98.6 Fahrenheit; otherwise, a urinalysis will be unsuccessful.
- Your sample's temperature range should be tested within four minutes of submission.
- If your samples are not submitted within an hour, then they have to be put under refrigeration.
Here’s the deal:
Urine tends to fluctuate in temperature according to the surrounding environment, and that is why it is advisable to keep regulating the temperature at all costs.
If not regulated properly, pee samples will either get destroyed or discolored. This is because urine changes color when left in cold temperatures.
What is even worse is that it will definitely give you a failed result if you don't keep the temperature in check throughout the whole process.
Let's be honest... urine drug tests can be really stressful, especially if the urinalysis is for a job. But do not worry, we'll have everything laid out for you in just a second.
Here are some thoroughly researched facts, compiled into a detailed explanation, about how to keep pee warm and at the right temperature before a drug screening test.
DON'T TAKE ANY CHANCES...
How to Keep Urine Warm for a Drug Test
- Place the fresh pee sample in a sealed plastic bag.
- Place it beside your body. The most practical area is to put it on your thighs.
- Make sure you keep the bag close to your body until the test to ensure the fresh sample does not lose its heat.
37 degrees Celsius or 98.6 degrees Fahrenheit is the average temperature  range of the human body. Knowing this can come in handy in keeping the synthetic urine warm.

How Long Can You Keep Pee for a Urinalysis?
Some people like to plan well ahead and try and store clean artificial samples for future tests.
However, what it does mean that you need to store the samples in the freezer instantly. Once frozen, the urine sample can last up to 6 months, at least for the really good brands.
Stay tuned for our recommended product, so you won't have issues when the time comes to use it.
The only downside of this is that you have it stuck in your freezer. So make sure you seal it properly or you will stink the house out.
However, the good news is that you won't be caught unprepared when that random drug test comes around the corner.
Synthetic Urine Can Be Heated Up In A Microwave. But...
To me, this approach is just not worth the risk.
Using a microwave is the trickiest method of all. However, it can work quite well if you get it exactly right.
The secret is not to overdo it. Start by putting the piss sample in a container. Avoid the use of a metal or steel container. The most effective container, in this case, should be made of a plastic material. Set the microwave for around 10 seconds. The power of your microwave might vary, but as long as you only heat it between the 8 and 12-second range, you’ll be fine.
Check the temperature to make sure it does not go overboard. If the final temperature is past what was expected, you can always allow it to cool. Keep in mind the temperature range should not be too low or again too high for that matter.
Microwave heating is always a very risky approach to take.
Let me explain...
If you overheat the urine, your screening test will fail because urine tends to get destroyed by too much heat. The microwave method requires you to be very careful as heating the pee too long can damage it, meaning you will fail the test.
If you don't heat it for long enough and the sample is heat-tested when you submit it (as many of them are) you will fail the test for that reason alone. You got to keep it fresh!
The drug test urine temperature  when submitted is so crucial to your success. Do not mess up in this area. If the lab uses temperature strips for urine testing, then this does apply a little bit of pressure.
Better Solutions for Passing a Drug Test
Personally, I would never risk not passing a urine test and would always go with Clear Choice Sub Solution. It is by far the best brand that we've ever tested here on this website so do check it out.
Now back to the topic in hand...
Drug test cheating has been going on for the last couple of decades. Fortunately, some get away with it.
Two of the most frequent questions we receive in emails are:
- "How do I keep urine at body temperature?"
- "What temperature should urine be for a urinalysis? Should the temperature be the same throughout the whole process?"
If you don't know the answer to these questions you are probably going to fail the test.
However, applying the methods featured below to artificial products will increase the chance of passing a drug test.
For instance, heating the synthetic urine in a microwave might end up destroying the samples, by rapidly increasing the temperature of the urine to such an extent that all the ingredients get damaged.
People use synthetic products in cheating examinations, especially when it comes to high-profile situations. However, fake pee is more prone to damage than natural urine.
Scientists today have come up with numerous ways to detect fake urine. Methods such as the utilization of the human body temperature can only be applied if the sample is to be submitted within a short period. It’s quite hard to keep regulating the heat of a sample that is expected to be submitted in a week’s time.
The key aspect here involves making sure the urine samples are kept in a tightly concealed container.
Using Hand Warmers to Keep Urine Warm for a Drug Test
- Hand warmers are an easy way to heat and regulate your urine sample’s temperature before the examination.
- Wrap a hand warmer around your pee sample, which should be in a small container. Secure it tightly.
- Note: Hand warmers can heat at different temperatures and may last longer.
The use of human body temperature warming can be challenging at times, since not everyone will find the time and patience to keep warming the samples.
This is why I like using Clear Choice Sub Solution or the Monkey Dong. They both come with heating pads (my favorite method) that keep the temperature regulated for you.

Even if the samples are heated, once placed away from the body, they will slowly lose their heat and eventually go back to being cold. Keeping the temperature regulated at a constant state will require the samples to stay in a place where they can get access to heat or warmth at all times.
Remember, it is not advisable to let the samples cool down too much, since this will also affect the test results.
Heating Pads: The Most Reliable Solution to Stay Warm
Heating pads are small disposable packets that can be heated by hand and are used in generating heat.
You can then use the heating pads to wrap the container and use tape or an elastic band to secure it.
Heating pads work differently from each other, hence it is advisable to look for the one that works best. Make sure the heat pads are not wet, to ensure maximum heat generation.
If you're looking for heating pads, I would recommend the Monkey Whizz heating pads over Spectrum Lab's heating pads. Spectrum Labs is slightly cheaper, but my opinion is that it is worth spending the extra money to make sure you have the best chance at passing.
Keep in mind that even a single drop of water to the heating pad can cause alterations to the temperature, which can cause poor results.
The heating pad is regarded as the most efficient way of regulating the urine sample's temperature. This is because the samples get a constant supply of heat that is neither too much or too low, so as to cause alterations, at all times.
The best synthetic urine to be used with heating pads, that is currently hitting the headlines is Clear Choice Sub Solution. Many customers have used it in combination with the Monkey Dong (fake penis) in the event you have a "monitored" drug test or a Monkey Whizz (unisex delivery method).
This product comes with optimal heater packs that help keep the temperature regulated, which is a massive benefit and makes the whole process less complicated. Users have reported a high pass rate (99%+) on many forums commenting that these products were super easy to use and cost effective.
