Yes, you can use a clean glass jar for a urine sample, especially if you don't have the sterile container provided by the lab, but it must be thoroughly cleaned (boil if possible) and dry to avoid contamination, and sometimes a special additive is needed for 24-hour collections, so always follow your doctor's specific instructions.
If you are unable to fill the sterile container directly then you can use a different container (e.g. a glass jug or jar) and then pour the urine into the sterile container. Make sure the container you choose to use is very clean: wash it thoroughly and use boiling water to rinse it out before use.
Start with having a sterile urine collection pot, which you can get from your GP surgery or pharmacy. Using an old container from home can contaminate the sample and affect the results. If you experience frequent UTIs, ask for a couple to keep at home. Use soap and water before starting.
Sterile specimen container – use the sterile specimen container that has been provided for you. If one has not been provided, sterilize an ordinary jar and lid, such as a mayonnaise jar. Scrub and rinse them well. Boil in water for ten minutes to sterilize.

Very caustic substances such as Lime-A-Way, Drano, Detergent, or Methanol can interfere with the analytic or screening chemistry performance. Other substances like blood or soap even in tiny amounts can cause viscosity or cloudiness in the sample to the degree that the system cannot take a correct reading.
You also may use a clean paper or glass container, but not a metal container. 2. Pour the urine into the orange collection container after each time you urinate. Rinse the plastic cup or glass container with tap water after each use.
Provide yourself with a disposable urine container
Remember that in the case of bacteriological tests (urine culture), the container purchased must be sterile. It is unacceptable to urinate into bottles, jars and other containers not intended for this purpose.
Invalid result: Refers to the result reported by a laboratory for a urine specimen that contains an unidentified adulterant, contains an unidentified interfering substance, has an abnormal physical characteristic, or has an endogenous substance at an abnormal concentration that prevents the laboratory from completing ...
There's never a need to freeze a urine sample, because you won't want to use a sample that's older than about a day as it no longer accurately reflects the state of your health, Dr. Moore notes. So, don't pee in a cup three days before your appointment and expect it to keep.
A brown plastic container is typically used. A special pan that fits in the toilet or a urinal may be used to collect the urine. You will need to transfer the urine from the collecting container to the storage container. You will need to keep it cold.
However, about 1 in 3 urine samples are contaminated by bacteria which live on the skin or in the back passage. That means the test cannot establish whether there is a urinary tract infection. These samples waste time (because another sample is needed) and money (because tests must be run twice).
Storage and Transport: Store and ship at 2°C and 8°C to lab within 24 hours of collection. Note: specimens for urine culture should be refrigerated immediately after collection and no longer than two hours.
To collect a clean 'midstream' urine sample:
If you have been given a yellow-top urine monovette, or the pot you have been given is too small to urinate into directly, find a non-metallic container, e.g. a plastic or paper cup. The container must be washed thoroughly, rinsed and dried before use.
For 24 hours prior to collecting the specimen, you should avoid strenuous exercise as well as the following substances and drugs:
The fake pee was not designed to fool laboratory equipment. Therefore, it will be detected by the lab when your sample is submitted for verification. There are 12 other substances that are found in urine, aside from uric acid. We recommend that medical offices and companies perform visual confirmations of drug tests.
"In the event that a patient beats the monitoring, laboratories can use several different drug tests to determine if the urine was tampered with," explains Alejandro Amador, chief operating officer with Ammon Labs, a full-service toxicology laboratory, in an email.
Diluting the sample by adding water can also raise red flags by changing the color and/or temperature of your urine; a clear sample will probably be rejected, as will a lukewarm one. Ignore the rumor going around that drinking bleach will purify your urine.
Usually people try to cheat drug testing by three different ways: substituting their urine with synthetic urine or drug-free urine purchased from a clandestine source; drinking a commercially available product to flush out drugs; or adding an adulterant in vitro to the urine specimen after collection.
The "21-second pee rule" comes from a scientific discovery that most mammals over about 3 kg (like dogs, cows, elephants) empty their bladders in roughly 21 seconds, regardless of their size, due to physics involving urethra length and gravity. For humans, this serves as a loose benchmark: urinating significantly faster (e.g., under 10 seconds) or slower (over 30 seconds) might signal holding it too long or an overactive bladder, though it's not an exact diagnosis.
If you can't hand your urine sample in within an hour, you should keep it in the fridge at around 4C (39F) for no longer than 24 hours. Put the container of urine in a sealed plastic bag first. If the urine sample isn't kept in a fridge, the bacteria in it can multiply.
WASH YOURSELF OUT:
The general strategy for passing urine tests is to increase your fluid intake and urine flow so as to dilute the concentration of drugs in the sample below the threshold of detection. An hour or two before the test, you should fill your bladder with fluids – as much as you can drink.
Only use the urine sample bottle or test tube provided – if you have not been given one, ask at your family doctor (GP) surgery. The bottle or test tube does not need to be completely full – usually a small sample is enough for testing.
By catching the first 5-20 mL of the urine stream, the urine will contain sufficient organisms for detection. Collecting a larger sample will dilute the organisms and decrease the probability of detection.
That's when peeing in a cup – at your doctor's office, of course -- can help. Urinalysis is a valuable diagnostic tool that can help identify and rule out illnesses such as diabetes, certain cancers and kidney problems.
