Urine collection - infants refers to the method of getting a urine sample from a baby for testing purposes. It is usually done in a doctor's office, but can be done at home.
How the test is performed ...

Once the urine collection has been completed, the urine containers will be taken to the lab. If you are doing the urine collection at home, you will be given instructions on how and where to transport the specimen.

Urine collection
If possible, collect a sample from the first urine of the day.

Urine collection bag -- A special plastic bag is placed over the child's penis or vaginal area to catch the urine; this is not the best method because the sample may become contaminated.

~ bag: A plastic bag is taped over your child’s genitals to collect the urine, though contact with the skin can contaminate the sample.

~: If a sexually transmitted disease (STD) is suspected, a urethral swab for STD testing is obtained prior to voiding. ~ is then by clean-catch or catheterization.

Symptoms such as severe headache, changes in vision, reduced urine output, abdominal pain, fluid in the lungs and pelvic pain ...

A 24-hour ~ test will accurately measure how much urine the kidneys are producing in a day. A urinalysis can determine if protein or red blood cells are leaking into the urine indicating abnormal kidney function.

How to prepare for the test
Your doctor will tell you to take ammonium chloride capsules by mouth for 3 days prior to the test.

midstream ~ (MID-streem) (YOOR-in) (kuh-LEK-shuhn):
a method used to obtain a clean catch urine specimen. The patient starts a stream of urine into the toilet, and then catches the urine in a sample cup as the stream continues.

Random collection taken at any time of day with no precautions regarding contamination. The sample may be dilute, isotonic, or hypertonic and may contain white cells, bacteria, and squamous epithelium as contaminants.

To empty the ~ bag
You will need to empty the bag regularly, whenever it is half full, and at bedtime. If your doctor has instructed you to measure the amount of urine, do so before you empty the urine into the toilet.

24-hour ~ to check protein and Creatinine clearance (kidney function)
Blood tests -- kidney function (BUN, Creatinine), Electrolytes, tests for specific disease states (e.g., ANA for lupus, anti-GBM for Goodpasture's disease, ANCA level for Wegener's disease) ...

Sometimes a 24-hour ~ is needed for more accurate results. In this process, a person collects all the urine he or she voids during a 24-hour period. In general, this schedule is followed:
Day 1: The patient urinates upon arising as usual and discards that urine.

For a 24-hour ~, normal results are 90 mL/min–139 mL/min for adult males younger than 40, and 80–125 mL/min for adult females younger than 40. For people over 40, values decrease by 6.5 mL/min for each decade of life.
Urine osmolality.

Cystoscopy is a diagnostic procedure performed for diagnosis of a number of abnormalities of the urinary tract including blood of unknown origin in the urine (hematuria), urinary incontinence, abnormal ~ in the bladder (urinary retention), ...

A blood test and 24-hour ~ is done, if necessary. It is extremely important that the patient reviews all his medications with the Endocrinologist before testing and follows the recommendation of stopping some of them if needed.

24-Hour ~
Twenty-four hour ~ is performed by collecting a person's urine in a special container over a 24-hour period. The results of a 24- hour ~ may provide information to help your physician make or confirm a diagnosis.

The three-glass ~ method is used to measure the presence of white blood cells and bacteria in the urine and prostatic fluid.

Urine test-a 24-hour ~ to measure calcium excretion and kidney function (very important test)
Abdominal x-ray -a test that uses radiation to take a picture of the structures inside the body; can show kidney stones caused by high calcium levels ...

Also, a 24-hr ~ for calcium may be done to help diagnose this condition. Microscopic examination of the urinary sediment will help diagnose renal disease, as will renal biopsies.

Urinalysis: Urine spot test for arsenic and 24-hour ~ for total arsenic excretion; patient must not have consumed seafood for at least 3 days prior to ~; laboratory must 'speciate' the arsenic into organic and inorganic moieties, ...

Open a ~ bag (a plastic bag with an adhesive paper on one end), and place it on the infant. For boys, the entire penis can be placed in the bag and the adhesive attached to the skin. For girls, the bag is placed over the labia. Diaper as usual over the secured bag.

Lots of men hate the idea of using incontinence products -- the so-called adult diapers, ~ bags, and catheters. But if you're having a problem with male incontinence, these products can really help.

Ask for the instructions for using and caring for the catheter and the ~ bag. It's best to learn about this before your surgery, when you are most alert and able to understand and remember the directions.

Twenty-four hour ~s are made before dexamethasone is administered and on each day of the test. Since cortisol and other glucocorticoids signal the pituitary to lower secretion of ACTH, the normal response after taking dexamethasone is a drop in blood and urine cortisol levels.

The most widely used test is measurement of the total amount of cortisol contained in a whole day's ~. Medically, this is known as the 24-hour urinary free cortisol test.

Hearing aids, wheelchairs, braille equipment, communication devices, software, ~ systems, oxygen apparatus, and mobile hoists all help people with disability to function better in their daily life and to participate in the society.

A more sensitive test, which can detect microalbuminuria, requires ~ over 24 hours. You will also have to provide a blood sample for creatinine and urea nitrogen testing (see kidney disease and renal failure).

For practical reasons, the blood test estimation method for GFR is used far more often than the 24-hour ~ test for creatinine clearance.

3. Urine specimen
Collect 10-40 ml of urine in a STERILE 50 ml centrifuge tube or a urine specimen container. First-morning voided specimens are ideal, but any ~ is adequate. Have patient void directly into container, collecting from the first part of the urine stream if possible.

An increase in urine albumin (if the increase is relatively low it is called microalbuminuria) is often the first sign of damage to the kidney. This test is best done in a single ~ where the albumin/creatinine ratio is measured.

Diversion of urine involving placement of a tube within the kidneys in order to provide urinary drainage directly to an external ~ appliance.
Toxic to kidney cells ...

A 24-hour ~ should be done to measure the amount of protein in the urine, which indicates the extent of kidney damage done by the IgM protein. Serum viscosity should also be measured to detect early hyperviscosity syndrome.
