Because an unsterile container may carry other elements that will confuse the outcome of the results.
A sterile container must be used to collect a urine culture for many reasons. The sample collected cannot be tainted with any substance that is being tested for.
Urine is sterile until it passes out of the urethra. it then begins to accumulate bacteria from the surrounding area, so its sterile for a brief.
If properly sealed and stored, urine samples are good for testing up to 24 hours after the sample given. The urine sample should be in a sterile container within a sealed plastic bag and stored in a refrigerator.
Collection of a midstream clean-catch specimen.
Urine is considered sterile within the body.
When your urine is fresh it's actually sterile.
Normal, healthy urine is sterile when it's in the bladder and does not contain germs.
To collect a mid-stream urine sample, start by washing your hands thoroughly. Then, begin urinating into the toilet or a clean container without stopping. After a few seconds, carefully collect about 30-60 milliliters of urine in a sterile container. Make sure to avoid touching the inside of the container or the lid to maintain its sterility.
No. Normal urine should be sterile.
Urine is typically collected in a cup, for ambulatory patients, or with a catheter or indwelling cath for in-patients. The urine is sent to the lab and a tox screen is performed. Note that, in cases of drug testing, collection of the urine is at times officially witnessed in order to prevent substitution.
Urinalysis is the typical chemical evaluation of urine via a combination of tests. A microbiologic evaluation could be called urine culture and sensitivity (urine C&S) or MCS- Microscopy, culture and sensitivity of urine. In the US, microscopy is typically ordered with the U/A, not the C&S.
If you survive, clean the wound immediately and thoroughly. The bacteria in most lizards mouths (and especially the Komodo) are dangerous. If you have no sterile liquids available immediately use urine- in healthy people it is sterile! Piss on the wound to wash it. (Don't let the urine stand around in a container for many minutes.) Seek professional medical attention as soon as possible.
