Analysis of the urine of an infant

Laboratory diagnosis is an integral part of the medical examination. There can be different reasons for the appointment of tests: clarification of the diagnosis, a measure of the prevention of infectious diseases, a general collection of data on the state of health of the patient. In young children, the reliability of the test results( in particular, the analysis of urine) depends on the ability to initially properly collect the material. Indicators in infants also have their own characteristics, which parents need to know about.

Usually, morning urine is taken for the study, which is collected in a dry, clean container and covered with a lid. In young children, the minimum amount of urine for effective analysis is 15-20 ml. The term of delivery of the material taken for the study should not exceed an hour and a half. Long-term storage of urine inevitably leads to the decomposition of the basic element elements, to its turbidity and to a change in the reaction, and, consequently, to a distortion of the results.

The need to collect material for analysis puts most parents at an impasse. The parents of small girls are the hardest. After all, collecting urine from an infant who is not familiar with planting on a pot is not so easy. The most difficult task is not to miss the morning portion of urine.

How to assemble urine

Squeeze diaper or diaper

Unfortunately, quite a popular way. Such collection of material is unacceptable! In modern diapers as a filler contains a gel that absorbs moisture. If you manage to squeeze something out, it's the gel, not the urine. Squeeze the diaper is also pointless. Urine, passing through a similar filter, immediately lose all its properties.

Pour out peas

Not the best option. If the pot is aluminum, then it must be thoroughly boiled before the collection of the analysis. If the pot is plastic, it will not be helped by any means to clean it from bacteria and plaque. The number of white blood cells in such a urine will always be above the norm, and the result of bacterial inoculation can be completely deplorable.

In a jar of mayonnaise or baby food

Everything depends on the dexterity of the parents and the babbling of the baby. The jar with the lid should be prepared in advance in the evening. Rinse, rinse with boiling water and thoroughly dry. The child should be washed immediately after awakening. The procedure for collecting urine is more convenient in the bathroom. The sound of running water usually stimulates the baby to urinate. You can also offer the child to drink clean drinking water.

Collect urine in the mochebornik

Now in any pharmacy are selling plastic bags with a small hole and an adhesive at the edges. This is the most convenient and correct in terms of sterility option. After gluing the package to the "right" place of the child, parents can even put a diaper over it. You just need not forget to wash the child, and also do not stick the urine collection before going to bed "for the night."At night, the kid celebrates a small need more than once, so the package receives a mixture of different collection periods. The result of such an analysis may threaten to go to the hospital. The main drawback of the mochebornika - it can easily get unstuck. Many babies even contrive to tear off a bag that is constantly interfering with them.

If in healthy childrensuddenly detected deviation from the normal parameters( false positive result), for example, the presence of bacteria in urine or protein, the analysis should retake. Perhaps this was due to improper sampling material for analysis or due to improper preparation thereto. Yet it is important to know that some numerical figures obtained from different laboratories may vary.
