Urine Analysis And Laboratory Tests

The data of Urine analysis usually taken are divided into two; qualitative and quantitative data of Urine laboratory tests. Though a little darkness in the urine is associated with mild health disorders, major diseases that cause darkness in the urine include cystitis (an infection of the gall bladder), glomerulonephritis (inflammation of tissues in the kidney), acute tubular necrosis (a severe condition of renal failure) and also cancers related to the bladder, kidney and liver.
You may also be asked to collect a urine sample at home and bring it with you to the office or lab for testing. Urine is produced in your kidneys and passed through the urinary vet urine test tract (ureters, bladder and urethra) before being expelled from the body. In the lab a scientist analyses the sample to confirm the presence of white blood cells and bacteria.
Thirdly, the intermediate products are used in aerobic cellular respiration When the production of the intermediate products of fatty acid metabolism (collectively known as ketone bodies) exceeds the ability of the body to metabolize these compounds, they accumulate in the blood and some end up in the urine ( ketonuria ).

Cloudy urine can also be caused by the presence of white blood cells, indicating significant infection (bacterial or fungal), the passage of large quantities of protein in certain types of kidney disease (nephrotic syndrome), or simply contamination of the specimen at the time of collection (ointment, talcum powder, etc.). In all of these situations, it is the other urine test data that is useful (proteins, nitrites, microscopic analysis).
Presence of nitrites mostly occurs in the presence of bacteria with the inherent capability to convert urinary nitrates into nitrites such as E. coli, Klebsiella, Proteus, Pseudomonas, Enterobacter and Citrobacter; hence, the presence of nitrites in urine is highly suggestive of UTI.

Many times courts order those who have been convicted of DUIs to have random urine tests, however, because if a person has been drinking at night and is called the next morning to appear for a random urine test, the test will reveal alcohol in the urine.
Urine that's infected may have a ‘fishy' smell, but keep in mind that many of the body's waste products are excreted in the urine, and that includes waste products from medicines; the urine of someone who is taking antibiotics for instance, can smell very odd and can even turn an orangey colour, but these findings are quite normal.
The types of urine sample you might be asked for include a random specimen, first morning specimen or timed collection. Blood cells aren't found in urine normally. Foam can be a sign of kidney disease, while cloudy urine may mean you have an infection. A catheter is a good way to collect a urine sample when there is not much urine in the bladder.

Sometimes the urine contains enough blood to be visible, making the urine appear red or brown. Your urine may be examined under a microscope if there is an abnormal finding in one of the first two phases listed above or if your doctor specifically requests it.
Girls around the age of three may be cultured to see if they have asymptomatic bacteriuria or hidden bacteria in the urine, which can cause health problems. Frequent urinary tract infections. If a urinary tract infection is suspected, a urine test may show blood or bacteria in the urine.
For example, a method to obtain an uncontaminated urine sample involves passing a catheter through the urethra into the bladder. Macroscopic urinalysis notes the amount, color, and clarity of the urine as well as any other visible characteristics of the urine such as the presence of blood or blood clots , precipitates, or sediments.
