The majority of pharmacies and medical supply stores carry these containers. Once you have collected it in the appropriate container, store it in a cool place like a refrigerator.

Hygienic Collection and Storage of Urine Samples

The following steps go over how to properly collect urine samples for drug testing and emphasize the value of cleanliness and preventing contamination:

Step 1: Get ready

It is essential to check that the collection area is clean and free of contaminants before taking the urine sample. Use a sterile collection cup for the sample and thoroughly wash your hands in soap and water before handling anything. Keep your hands and other objects away from the sample and the inside of the cup.

Step 2: Collecting

To protect the privacy of the person being tested, the urine sample collection should be done in a private setting. Making sure that the sample is free of any foreign materials is crucial. To accomplish this, the person must wash their genital region with soap and water, followed by drying it with a fresh towel. The person should then urinate into the clean cup to make sure that the urine does not exceed the line on the cup.

Step 3: Storage

It is essential to store the urine sample after it has been taken in a sterile, airtight container made specifically for collecting urine. To prevent the introduction of contaminants, avoid moving the sample from one container to another. The name of the owner and any other pertinent details, like the time and date of collection, should be written on the container.

Selecting the Right Container for Storing Urine Samples

When choosing a container to store urine samples for drug testing, some things to keep in mind are:

  • Material: When choosing a container to store urine samples, the material should come first. The container needs to be constructed from a substance that is compatible with the urine sample and won’t obstruct the testing procedure. Containers for urine samples are frequently made of plastic, glass, and polypropylene.
  • Airtightness: To avoid oxidation and sample degradation, urine samples should be stored in airtight containers. Additionally, an airtight container will stop the sample from leaking or evaporating, which could skew the test results.
  • Durability: The container must be strong enough to endure handling and transportation without breaking or leaking. It’s crucial to pick a container that will be able to withstand any possible impacts or shocks that may happen during transport.
  • Compatibility: The container needs to be appropriate for the kind of drug test being performed. For instance, the container should be made to accommodate the preservative if the drug test calls for adding one to the urine sample.
  • Capacity: The container used to store urine samples should have enough space to hold the necessary volume of urine for the test. The minimum and maximum fill levels should be clearly marked on the container you choose.

Temperature Control

Maintaining the integrity of urine samples for drug testing depends on temperature control. The sample may deteriorate as a result of improper storage conditions, which could compromise the validity of the test results. In this article, we’ll go over the significance of temperature control when keeping urine samples for drug testing and offer instructions for doing so.

To preserve the stability and integrity of the urine sample, it should be stored in a specific temperature range. The sample may deteriorate or become contaminated if the temperature is too high or too low, which could produce unreliable test results. Urine samples should be kept between 2 and 8 degrees Celsius (36 and 46 degrees Fahrenheit) for drug testing.

Guidelines for Temperature Control

Take into account the following recommendations to ensure proper temperature control when storing urine samples for drug testing:

  • Use a Refrigerator: The most typical way to store urine samples for drug testing is in a refrigerator. The refrigerator should be kept at a temperature of 2–8°C (36–46°F). Avoid freezing the urine samples because doing so can lead to crystal formation and compromise the validity of the test results.
  • Implement a thermometer: The storage area for urine samples can be monitored using a thermometer. To guarantee that the temperature readings are accurate, the thermometer should be calibrated frequently.
  • Monitor the Storage Area: It’s crucial to routinely check that the storage area’s temperature stays within the advised range. 
  • Avoid Heat or Sunlight: To avoid exposure to heat or sunlight, urine samples should be kept in a cool, dark environment. The urine sample may deteriorate when exposed to heat or sunlight, which could compromise the validity of the test results.
  • Use a Temperature-Controlled Transport System: In order to keep the urine samples within the recommended temperature range, it is crucial to use a temperature-controlled transport system if they need to be transported. This will make sure the samples are accurate and stable during transportation.


In conclusion, keeping urine samples for drug testing is an important procedure that needs to be done with meticulous attention to detail. Correct sample collection, the selection of the appropriate container, and proper temperature control during storage and transportation are crucial. Any departure from these recommendations may jeopardize the sample’s reliability and impact the validity of the test results.

People can make sure that the results of a drug test are accurate and reliable by adhering to the best practices for storing urine samples. To prevent any errors that might result in false-positive or false-negative results, it’s crucial to adhere strictly to these rules.
