What is no growth in urine culture?
No growth in a urine culture means that there was no bacterial growth detected in the sample. This could indicate that there is no bacterial infection present in the urinary tract or that the sample was not collected properly. Further testing may be needed if symptoms persist.
Checking the bacterial contamination in drinking water by testing sulphide ion?
hi there you you can add a water purefying machine to your taps and filter out bacterial contaminates,cholrine,fluride ect . this will make your water very clean and contaminat free for human consumption if you want to find out more info here trevordye.org Thanks trevor dye
What organisms are used as indicators of bacterial contamination?
Organisms commonly used as indicators of bacterial contamination include coliform bacteria, particularly Escherichia coli (E. coli), and enterococci. These microorganisms are typically found in the intestines of warm-blooded animals and can indicate fecal contamination in water or food. The presence of these indicators suggests that pathogens may also be present, posing potential health risks. Monitoring these organisms helps assess water quality and public health safety.
What will be the reaction of urine in a polyethylene tank?
Urine stored in a polyethylene tank will not react with the tank material, as polyethylene is a non-reactive plastic. However, if the urine is left for a long time without proper cleaning, it may develop odors or bacterial growth. Regular cleaning and maintenance are important to prevent these issues.
How does heat effect urine?
Urine doesn't create or excrete heat. It dissipates heat and it would be the value of the temperature and the volume of the urine probably expressed in "calories" of heat energy. For humans the urine exits the body at about 99 degrees, but the volume would be a variable.
What is no growth in urine culture?
No growth in a urine culture means that there was no bacterial growth detected in the sample. This could indicate that there is no bacterial infection present in the urinary tract or that the sample was not collected properly. Further testing may be needed if symptoms persist.
Positive nitrates in urine?
Positive nitrates in urine indicates that you may have a Urinary Tract Infection (UTI) or bacterial infection in areas of your body that produce or hold urine such as your kidneys, bladder, or urethra.
What is the effect of the contanination with water and or urine to a fecal samples?
Contamination of fecal samples with water or urine can significantly alter the results of microbial and biochemical analyses. Water can dilute the sample and potentially introduce foreign microorganisms, while urine can introduce additional compounds that may interfere with tests or skew results. Such contamination can lead to inaccurate interpretations of gut health, infection presence, or the effectiveness of treatments. Therefore, maintaining sample integrity is crucial for reliable diagnostic outcomes.
What is mixed growth contamination in urine?
Mixed growth contamination in urine refers to the presence of multiple types of bacteria in a urine sample that is not consistent with a typical urinary tract infection (UTI). This can occur when the sample is contaminated during collection or handling, leading to the growth of various microorganisms that do not originate from the urinary tract. Such contamination can complicate diagnosis and may result in inappropriate treatment if misinterpreted as a true infection. Proper collection techniques and timely analysis are essential to minimize mixed growth contamination.
What occurs if a urine specimen is allowed to stand for more than 1 hour at room temperature?
If a urine specimen is left standing for more than 1 hour at room temperature, it may undergo bacterial proliferation, leading to potential contamination. Additionally, there can be changes in the chemical composition of the urine, such as breakdown of certain components like glucose and ketones. This can result in inaccurate test results and difficulty in interpreting the findings.

How does standing urine influence urine pH?
Standing urine can lead to changes in pH due to bacterial growth, which can increase the pH by producing ammonia and other alkaline substances. Additionally, standing urine may allow for increased evaporation, leading to concentration of acidic components and potentially lowering the pH.

Where on your body can you attach urine for a drug test?
For a woman, I suggest buying the smallest container of synthetic urine especially. Woman can put a bottle of fake pee in their "safe" or vagina. It will keep ur fake urine exactly body temp. Never put fake urine into a different bottle than it was bought in. May cause contamination.
How do penicillin effect urine output?
Penicillin can affect urine output primarily by influencing kidney function. It is known to be excreted through the kidneys, and high doses may lead to increased urine output due to osmotic effects. Additionally, allergic reactions or side effects may cause changes in kidney function, potentially impacting urine production. However, in most cases, penicillin does not have a significant direct effect on urine output for the general population.
What are the changes in urine when refrigeration?
When urine is refrigerated, there may be changes in color, odor, and appearance. Cold temperature can cause urine color to darken, sediment may form at the bottom, and a stronger odor may develop due to bacterial growth. It is still safe for testing within a certain timeframe, usually up to 24 hours, but any significant changes should be noted.
What happen when a urine specimen is allowed to sit for an hour?
When a urine specimen is allowed to sit for an hour, bacterial growth may increase due to the warm and moist environment, potentially leading to inaccurate test results. Additionally, the pH and chemical composition of the urine may change, which can affect the accuracy of certain tests such as urine culture or urinalysis. It is always best to process urine specimens promptly to ensure accurate results.
