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 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 squamous epithelial cells in urine?
Squamous cells in a urinalysis test only indicate contamination from the genital tract. Check out this page for more information:http://www.irvingcrowley.com/cls/urin.htmIt's very helpful, check it out!

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 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.
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.
What are squamous cells in urine?
In humans, squamous cells are found in the epidermis of the skin, in the lining of hollow organs and in the respiratory and digestive tracts. Squamous cells in urine may indicate contamination due to the presence of bacteria.
What are four signs of contamination you might note when inspecting a work area?
Four signs of contamination in a work area include unusual odors, which may indicate chemical spills or biological hazards; visible spills or stains on surfaces, suggesting potential leaks or spills; the presence of pests or their droppings, indicating possible food contamination; and discoloration or unusual growths on surfaces, which could signal mold or bacterial contamination. Additionally, the presence of dust accumulation or residues can also be a sign of inadequate cleaning and potential contamination risks.
Is it safe to reheat milk twice?
Reheating milk twice may increase the risk of bacterial contamination, potentially leading to foodborne illness. It is generally recommended to only reheat milk once to ensure safety.
How much cooked prawns can you eat while pregnant?
As they are cooked prior to eating they are safe to eat from the bacterial contamination point of view. However they may contain heavy metals. For more information see the associated website.
