When urine is to be cultured for bacteria, a midstream clean-catch urine specimen is typically required. This method helps to minimize contamination from the external genitalia. The urine should be collected in a sterile container and ideally sent to the laboratory promptly for accurate results.

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
How do you Calculate the bacteria per ml present in a contaminated urine specimen?
To calculate the bacteria per milliliter (ml) in a contaminated urine specimen, first, perform a quantitative culture by diluting the urine sample and plating it on an appropriate agar medium. After incubation, count the number of colonies that grow on the plate. Multiply the number of colonies by the dilution factor and the volume of the plated sample (in ml) to determine the concentration of bacteria per ml in the original urine specimen. For example, if you plated 0.1 ml of a 1:100 dilution and counted 50 colonies, the calculation would be 50 colonies × 100 (dilution factor) × 10 (to convert 0.1 ml to 1 ml), resulting in 50,000 bacteria/ml.
How do you collect specimen for benze-jones protein test?
To collect a specimen for a Bence Jones protein test, a 24-hour urine collection is usually required. You will be provided with a container to collect all urine passed during a 24-hour period, starting with an empty bladder and ending with a final collection at the same time the following day. The urine specimen is then sent to a lab for analysis to measure the presence of Bence Jones proteins.
What is a random urine specimen?
A random urine specimen is a urine sample collected at any time without following a specific time schedule or fasting requirement. This type of specimen is commonly used for routine screenings or as a general sample to check for various medical conditions.
Is a microbiology test done with a urine specimen?
yes, example of urine culture and sensitivity.
Is typhoid related to urinal infection?
Typhoid bacteria can be cultured from the urine of the patient of typhoid. But then the transmission of infection by way of urine is less likely.
What is meant by cath spec?
A "cath spec" is a catheterized urine specimen. Most urine specimens are voided specimens when the patient attempt to collect the urine while voiding. The risk of contaminating a voided specimen, with skin bacteria, is high even when the patient is careful. Therefore, a catheterized urine specimen is considered a reliable urine sample.
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 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
What illnesses can a urine culture detect?
Abnormal results, or a positive test, where bacteria are found in the specimen, may indicate a urinary tract infection.

What type of urine test is a colony count?
A colony count is a test that detects bacteria in urine that has been cultured for 24-48 hours. It is used instead of a routine urinalysis when a patient's symptoms suggest a urinary tract infection.
What is urine specimen infection?
A urine specimen infection, often referred to as a urinary tract infection (UTI), occurs when harmful bacteria invade the urinary tract, leading to inflammation and infection. Symptoms may include frequent urination, pain or burning during urination, and cloudy or strong-smelling urine. Diagnosis typically involves analyzing a urine sample to detect the presence of bacteria, white blood cells, and other indicators of infection. Treatment usually involves antibiotics to eliminate the infection.
Which type of urine specimen is needed to detect an infection?
Typically midstream urine is taken as a urinary specimen, when you have urinary tract infection. It is good precaution to scrub the genital area with some mild soap like glycerin soap, before you take the urine specimen.
How soon must a urine specimen reach the laboratory?
How soon a specimen of something must reach the laboratory depends partly on the reason for which it is being sent to the laboratory, environmental conditions during storage and transit, and the stability of the substances the specimen consists of. A urine specimen must be refrigerated during storage and transit and arrive in the lab within an hour or two. It cannot sit out because warmth will allow bacteria, if present, to begin to grow in numbers.
Is refrigeration required to store urine?
I read urine was good for 24-48hrs. does it have to be refigerated during this time? Yes it does need to be refrigerated. Without refrigeration, the specimen can last about 24 hours. If refrigerated, it can last from 5 days to 2 weeks (according to who you ask), and apparently, freezing can let the specimen last up to a year. Otherwise, bacterial growth can taint the specimen.
What is urine culture and sensitivity?
Urine culture is when a doctor orders a urine specimen to be evaluated in a lab to determine exactly what kind of bacteria are living in it and causing problems. "Culture" means to grow, and they literally grow the bacteria so that they can test different antibiotics on it. Some antibiotics may kill the bacteria, and some antibiotics have no effect on the bacteria. This is the "sensitivity" part. If a bacteria is sensitive to an antibiotic, it would be a good choice for treatment of the infection. If it is not sensitive, the it is resistant to the antibiotic and it won't produce a cure.
