You can store urine in the freezer for up to six months. However, if you prefer to keep it in the fridge, you can only store it for up to 24 hours.

Storing human urine can be risky as it can spoil easily.

But don’t worry, I’ll tell you how to minimize those risks and keep your urine fresh for a drug test.

If you plan to store clean urine for a future drug test, you actually need to go through four steps:

  1. Get a container.
  2. Collect the urine.
  3. Store it properly.
  4. Prepare it for a drug test.

I’ll cover all these steps in detail.

Choosing the right container for storing urine

When it comes to storing urine for a drug test, the type of container you use is crucial.

You’ll need at least 30ml of urine for a drug test, but the Department of Transport requires 45ml of urine.

The best option is to use a 50ml plastic bottle.

bottles for storing urine

Visine bottles are too small, just 15ml, and big plastic bottles are not good because there’s a lot of air, and there are more chances that the urine will spoil.

Another reason for using small bottles is the drug testing procedure.

Before the drug test, you will be required to empty your pockets and remove unnecessary clothes like hats, jackets, etc.

The collector will look through your items, and if he finds something intended to cheat the drug test, you will be required to go through the directly observed drug test.

Collectors are aware that visine bottles are used to bring urine to drug tests, so you need a small bottle that you can hide discreetly on your body.

By using a 50ml plastic bottle, you can avoid any issues during the drug testing procedure and store your urine securely.

The best thing to put urine in for a drug test is  a special urine bottle with an attached temperature strip. The temperature strip will help you know the temperature of the urine before submitting it.

You can purchase such a bottle on Amazon, or you can buy a temperature strip separately and attach it to any bottle.

How long is urine good for at room temperature for a drug test?

According to Labpedia, urine can stay good at room temperature for up to 2 hours. Research published in PubMed says it can sit out for up to 40 hours.

If you’re using someone else’s urine, make sure it doesn’t spend more than 2 hours at room temperature. Alternatively, you can use synthetic urine, which doesn’t have a time limit and stays good as long as you need it.

To keep your urine sample fresh overnight or for less than 24 hours, you can put it in the fridge.

Collecting clean urine

Urine can spoil quickly because of bacteria in urine and air, so the room for collecting must be as clean as possible.

To prevent bacteria from your hand getting into the urine, use vinyl disposable gloves.

Pee in a bottle and close it as fast as possible to avoid contamination.

The best option is to put the urine directly into the bottle that you will use for the drug test.

Pouring urine from one bottle to another will add bacteria to the urine and increase the chances of spoiling.

By following these simple steps, you can collect clean urine that is ready to use for a drug test.

It’s important to remember that proper storage and handling of urine is crucial to ensure accurate and reliable drug test results.

How long can you keep a urine sample in the fridge?

To preserve clean urine for a drug test, you can keep it in the fridge overnight. Theoretically, it can stay in the fridge for up to a month. However, after a month, it won’t be good for detecting drugs.

Over time, urine changes its composition and may fail validity checks for pH, creatinine, specific gravity, etc. The best practice is to keep it in the fridge for no more than 24 hours. Use an airtight sterile container to prevent contamination.

Consider the time it takes to get to the drug testing facility. Ensure the total time the urine spends at room temperature is less than 2 hours.

Can you freeze urine?

To store urine for a drug test, you need to prevent bacteria from growing. You can safely freeze urine and thaw it before the test.

According to an article on PubMed, urine samples can be safely frozen and thawed at least five times. The lab cannot tell that the urine was frozen.

Theoretically, expensive techniques could detect changes in urine composition, but pre-employment tests don’t use these methods.

To store your urine in the fridge, use a proper container. It must be clean and the right size. Drug tests require 1-1.5 ounces of urine, so use a 2-ounce container.

It’s best to use the bottle you’ll use for your drug test to avoid contamination. Special bottles with temperature strips, available on Amazon, are useful for checking the urine temperature before submitting it. They’re also discreet, so you can hide them in your scrotch area.

Store this bottle in the freezer, and you can keep it there for up to 1 year.

How to store urine for a drug test

First, you need to decide how long you need to store it.

how to store urine for a drug test

Urine can sit out unrefrigerated at room temperature for about 10 hours without spoiling. So, you can collect it in the evening and store it overnight for a morning drug test.

However, if you need to store it for up to 24 hours, you should put it in the fridge. In a fridge urine is good for up to 24 hours.

Make sure to seal the urine bottle to prevent any bacteria in the fridge from getting inside the bottle and contaminating the urine.

It’s even better to put the bottle in a sealed bag.

If you need to store the urine for a longer time, you can freeze it for up to 6 months.

To freeze the urine, put the sealed urine bottle in a plastic bag and place it into the freezer.

Remember that freezing the urine multiple times increases the risk of contamination and that the urine will spoil, so I recommend freezing it only once.

If you need to freeze the urine for several uses, use several smaller bottles.

Thawing frozen urine

You can thaw frozen urine using three methods:

Room temperature: Thawing it at room temperature can take up to 1 hour for a 50ml urine bottle.

Warm water: You can place the urine bottle in a pot with warm water. It will take about 20 minutes to thaw, depending on the water temperature.

Make sure that the water is not too hot and is about body temperature – this will prevent rapid bacteria growth and degradation of the urine.

Microwave: Thawing in a microwave will take 45 seconds to 2 minutes.

Place the urine bottle in the microwave and use 10-second intervals to thaw the urine.

Keep watching the urine temperature to ensure it does not overheat. If you overheated the urine, let it sit out for several minutes to cool down.

Can you use 3-day-old urine for a drug test?

You can only use 3-day-old urine if you’ve stored it in the freezer. Refrigerating it will result in spoilage due to bacteria growth.

Below is a photo comparing fresh urine to urine that has been refrigerated for 3 days.

As you can see, the urine appears cloudy and the presence of bubbles indicates a significant amount of bacteria growth.

Can you use someone else’s urine?

IMPORTANT

I must emphasize that we do not recommend using someone else’s urine for a drug test.

You never know what drugs the person may have actually used, even if they think they’re clean.

For instance, cannabis metabolites can stay in the body for a long time, even if the person smoked it weeks ago.

Additionally, human urine spoils quickly, and if it’s not stored properly or submitted at the right temperature, it will be detected during the drug test.

So, avoid taking the cheap shortcut of using someone else’s urine.

A word of caution

If you’re facing a drug test and considering submitting your own clean urine or someone else’s, think twice.

You can’t be sure that the urine is unspoiled until it’s submitted.

If passing the drug test is essential for you, for instance, if you want a high-paying job, then you need to consider using high-quality synthetic urine instead.

It costs only $90 and will allow you to pass the drug test without any hassle.

But, you need to ask yourself, is the $90 worth the risk of failing the test and going through direct observation procedure?

Incorrect urine temperature is the primary reason people fail drug tests when submitting synthetic or someone else’s urine.

Therefore, you still need a reliable method to maintain the sample’s warmth before a drug test. This often involves purchasing hand warmers or heat pads.

However, you could avoid all that trouble by opting for high-quality synthetic urine and going to your drug test confidently without any risk of getting caught.

Choose these synthetic urine kits and say goodbye to urine storage hassles!
