Urinalysis: routine cultures
What is it?
A routine urine culture can detect the amount of germs (such as bacteria) present in a person's urine.
Once the urine sample has been collected, a technician will keep it in favorable conditions for the reproduction of microorganisms. Under normal circumstances and in the absence of infection, only a small amount of germs are found in a person's urine. If a greater amount of germs is detected, the technician will use a microscope or chemical tests to determine the specific type of germs that are growing in the culture. In the event that the doctor diagnoses an infection, the technician will also perform tests to determine which medications will be the most effective in eliminating the detected microorganisms.
Why is it done?
Urine culture is used to diagnose a urinary infection and determine what types of germs have caused it. The pediatrician will request a urine culture if your child:
- complains of pain when urinating
- often feels an urgent need to urinate but does not produce much urine (what is medically known as "bladder tenesmus").
- you have a fever of unknown origin or abdominal pain.
- You have had a urine test with abnormal results, especially if you have a high number of white blood cells.
- You have completed a complete cycle of treatment of a urinary infection and are interested in knowing if the infection has disappeared.
preparation:
To prepare a urine culture, no preparation is required other than cleaning the area surrounding the urinary opening. Tell the pediatrician if your child is taking antibiotics or has recently taken them.
The procedure:
Sample collection should only last a few minutes. When your child is in the pediatrician's office, they will tell you to urinate in a sterile sample collection container. If your child still does not know how to use the bathroom and is not able to urinate into the container, they should insert a catheter (a soft, narrow tube) into the bladder to collect the sample.
The skin surrounding the urinary opening should be disinfected just before urine collection. In this clean urine collection method, you or your child will clean that skin with a special disinfectant wipe. Then your child will urinate in the toilet, momentarily stop the stream of urine and then continue urinating inside the container. The goal is to collect a urine sample in the middle of urination. The container should not touch your child's skin. Make sure that both you and your child wash their hands well before and after the process.
Sometimes it is advisable to collect the sample first thing in the morning, just after your child gets out of bed. In these cases, you may be asked to help your child collect the sample. And you should also take the sample to the laboratory, where a technician will evaluate the presence of germs. Follow the conservation and transport instructions provided by the laboratory.
What to expect:
Since the test only involves urinating normally, your child should not experience any discomfort if he knows how to use the bathroom and control the urine to provide the sample. (If a catheter is to be placed to collect the sample, you may experience temporary discomfort related to the procedure.) It is important to keep the area around the urinary opening clean just before the test and collect the urine sample in the middle of the urination.
Obtaining results:
The results of a urine culture will be available within one to three days. The pediatrician will deliver the results and explain what they mean.
Risks:
The procedure of collecting a urine sample to perform a culture is not associated with any irrigation. If it is necessary to use a catheter, its placement may cause some temporary discomfort. Expose any questions you have about the procedure to the health professional who takes your child.
Help your child:
Urinating to collect a urine sample is usually painless. If you explain to your child why they should do the test and how it will be done, it will help clear any fear or doubt you may have about it. Make sure that the child understands that the urinary opening must be well cleaned before the test and that he must collect a urine sample in the middle of urination.
