A clean catch is a method of collecting a urine sample to be tested. The clean-catch urine method is used to prevent germs from the penis or vagina from getting into a urine sample.
Alternative NamesUrine culture - clean catch; Urinalysis - clean catch; Clean catch urine specimen; Urine collection - clean catch
How the test is performedIf possible, collect the sample when urine has been in your bladder for 2 to 3 hours.
You will use a special kit to collect the urine. It will most likely have a cup with a lid and wipes. You should also spread a clean towel on the counter or sink.
Wash your hands with soap and warm water.
GIRLS AND WOMEN
Girls and women need to wash the area between the vagina "lips" (labia). You may be given a special clean-catch kit that contains sterile wipes.
- Sit on the toilet with your legs spread apart. Use two fingers to spread open your labia.
- Use the first wipe to clean the inner folds of the labia. Wipe from the front to the back.
- Use a second wipe to clean over the opening where urine comes out (urethra), just above the opening of the vagina.
To collect the urine sample:
- Keeping your labia spread open, urinate a small amount into the toilet bowl, then stop the flow of urine.
- Hold the urine cup a few inches from the urethra and urinate until the cup is about half full.
- Stop the flow and place the cup on the sink. You may finish urinating into the toilet bowl.
BOYS AND MEN
Clean the head of the penis with a sterile wipe. If you are not circumcised, you will need to pull back (retract) the foreskin first.
- Urinate a small amount into the toilet bowl, and then stop the flow of urine.
- Then collect a sample of urine into the clean or sterile cup, until it is half full.
- You may finish urinating into the toilet bowl.
INFANTS
You will be given a special bag to collect the urine. It will be a plastic bag with a sticky strip on one end, made to fit over your baby's genital area.
If the collection is being taken from an infant, you may need extra collection bags.
Wash the area well with soap and water, and dry. Open and place the bag on your infant.
- For boys, the entire penis can be placed in the bag.
- For girls, place the bag over the labia.
You can put on a diaper over the bag.
Check the baby often and remove the bag after the urine collects in it. Active infants may displace the bag, so you may need to make more than one attempt. Drain the urine into the container you were given and return it to the health care provider as directed.
AFTER COLLECTING THE SPECIMEN
Screw the lid tightly on the cup. do not touch the inside of the cup or the lid.
- Return the sample to the health care provider.
- If you are at home, place the cup in a plastic bag and put the bag in the refrigerator until you take it to the lab or your health care provider's office.

What test requires a clean-catch midstream specimen?
Any test for bacteria in the urine, such as a test for a urinary tract infection, will require a "clean-catch," which means you will have to clean the genital area first and catch the urine mid-stream.
What is a CC midstream urinalysis?
I believe a CC midstream urinaylsis is referring to a "clean catch midstream UA" In other words, you wipe with a cleaning towelette according to the directions, then you begin to urinate and before you are finished, you will catch some of the urine whil in midstream.
How can you ensure the freshness of a urine sample?
To ensure the freshness of a urine sample, it is important to collect it in a clean, sterile container as soon as possible after it is produced. It should be stored in a refrigerator or kept on ice until it can be tested. This helps prevent bacterial growth and maintain the integrity of the sample for accurate results.
How can you get a clean urine from heroin when i smoked it last night and got to give sample today?
It is not possible to rid your body of heroin that quickly. It is important to be honest in situations like this and seek help if needed. Trying to alter or cheat a drug test is not recommended and could have serious consequences.
What are the types of urine specimen?
The types of urine specimens commonly used for testing include random urine, first-morning urine, clean-catch midstream urine, and 24-hour urine collection. Each type provides different information based on the timing and collection method.
What technique is used to obtain uncontaminated urine sample?
A clean-catch midstream urine sample is typically obtained by cleaning the genital area, then starting to urinate into the toilet before collecting a sample midstream in a clean container. This technique helps reduce the risk of contamination from the surrounding skin and the initial stream of urine.
What are Nine types of urine specimens that can be collected?
Random urine sample First morning urine sample Midstream clean-catch urine sample 24-hour urine collection Timed urine sample Postprandial urine sample Suprapubic aspiration specimen Catheterized urine specimen Pediatric urine bag specimen

The name given to a urine protein test is the Bence-Jones. It requires a clean catch urine sample of between one and two ounces. It can be used to test for things such as lymphoma, amyloidosis and chronic lymphocytic leukemia.
Which sample is not routinely collected by sterile needle aspiration?
A sample that is not routinely collected by sterile needle aspiration is a urine sample. Urine is typically collected using a clean catch technique or catheterization rather than aspiration. Sterile needle aspiration is more commonly used for obtaining samples from fluids or tissues, such as abscesses or cysts.
What kind test require a clean catch midstream urine test?
A clean catch midstream urine test is typically required for urine culture and sensitivity tests to diagnose urinary tract infections (UTIs). This method minimizes contamination from bacteria found on the skin or in the urethra, ensuring a more accurate assessment of the urine sample. It may also be used for routine urinalysis to evaluate kidney function or other urinary tract conditions.
Would you expect to find Red Blood Cells under the microscope in a clean catch urine sample?
No, red blood cells should not typically be present in a clean catch urine sample. The presence of red blood cells in urine may indicate potential health issues such as urinary tract infection, kidney stones, or other underlying conditions that warrant further investigation.
Can leukocytes appear because urine not clean catch?
Yes.
What type of urine is normally collected for urinalysis and urine culture?
For urinalysis and urine culture, a midstream clean-catch urine sample is typically collected. This method helps to minimize contamination from the skin and urethra, providing a more accurate representation of the urine. The patient is instructed to clean the genital area and then collect urine after discarding the initial stream. This technique is especially important for cultures to ensure reliable results for diagnosing urinary tract infections.
When the doc says the blood and pus in the urine specimen can be caused by collection what does he mean?
If a urine specimen isn't a clean-catch, mid-stream urine, it's possible for external blood or white blood cells to contaminate the sample, given the mistaken impression that there's urinary disease.
How is a urine culture and sensitivity collected?
A urine culture and sensitivity test is typically collected through a clean-catch midstream urine sample. The patient is instructed to clean the genital area with a provided antiseptic wipe, then urinate a small amount into the toilet before collecting the midstream urine into a sterile container. The sample should be sent to the laboratory as soon as possible for analysis to identify any bacteria and determine their sensitivity to antibiotics. Proper collection is crucial to avoid contamination and ensure accurate results.
