How to properly prepare for the study


For general analysis, urine must be sterile. If you neglect the norms of hygiene, urine can contain discharge from the genitals, and this will significantly distort the results of the study.

  1. Before collecting urine, it is imperative to wash the genitals with warm water and soap, a solution of potassium permanganate, furacilin.
  2. After the water procedure, you need to dry the genitals. A man should dry the head and opening of the ureter well with a napkin, moving the foreskin; women are advised to wipe the perineum from the urethra to the anus.
  3. During critical days, it is better for women not to donate urine for research.
  4. In order to achieve the sterility of the collected urine, a man must pull back the outer skin folds during urination and free the ureter as much as possible.
  5. A woman, in order to ensure sterility, must part her labia with her hands and thus open the ureter.
  6. If before this the patient underwent a cystoscopic examination of the bladder using a catheter, then for a general urine analysis, urine can be collected only after a week.

Collection of biomaterial for analysis in an adult


In order to conduct a full-fledged study, the amount of urine of an adult must be at least 130 ml.

It is preferable to purchase a special container for the delivery of urine for analysis at the pharmacy. It is a sterile plastic cup with a screw cap. In the absence of a container, a small, sterilized glass jar will do.

Do not touch the inner surface of the container and lid with your fingers, so as not to violate their sterility. In advance, stick a marker on the container indicating the data of the patient under study and the attending physician.

In some cases, if it was not possible to collect material for analysis immediately after waking up, it is allowed to use urine collected no earlier than 2.5 hours after the first morning urination.

  • Collecting urine can only be done after compulsory hygiene procedures.
  • Take the collection container with you to the toilet after removing the lid.
  • In order for the collected material to be sterile, it is necessary to put the first stream into the toilet, and only then collect the urine for analysis.

If a woman needs to be tested at a time when she has critical days, you should use a hygienic tampon immediately after water morning procedures. A tampon should be used in all cases if vaginal discharge occurs.

What you need to know when collecting material


As a rule, the doctor often asks to collect the entire portion of the morning urine for a general analysis, and only then take the required amount of material. This gives the most complete research result.

Before pouring the amount of urine required for analysis into a separate dish, first shake well the container with the collected biomaterial. The contents of the container will mix well, and urine with all the impurities present in it will be used for research.

It is forbidden to use a duck or a pot as a container for collecting urine when urinating - despite thorough rinsing, impurities contained in urine, urinary stone, settle on their walls. Freshly collected urine begins to decompose immediately under the influence of the phosphates it contains

After transfusing the biomaterial into the desired container, it should be tightly closed with a lid and taken to the laboratory no later than 2-3 hours after collection. It is recommended to store the collected urine in a cool place before testing to prevent its premature decomposition.

The procedure for collecting urine for analysis in infants


Collecting a general urine analysis from an adult is not very difficult - you just need to strictly adhere to the recommendations and rules of personal hygiene. However, mothers often ask themselves the question of how to collect a urine test from an infant - sometimes it is quite problematic to do this.

The baby is not yet able to control the process of urination, it is still early and useless to plant, and parents rarely manage to catch the moment when the baby is urging to urinate.

It is especially difficult when collecting urine from newborn girls. Male babies are easier to "catch hot" and put the container under the stream of urine in time.

One of the following methods will tell you how to properly collect urine from children from the first days of birth to one year.

1. Get a pediatric urine receiver from your pharmacy. This is a clear plastic bag that is glued to the baby's genitals. The receiver is designed so that urine is not spilled when urinating, and there is no possibility of mixing it with feces.

In order to get the correct amount of urine, in the morning, fasten the urine bag on the baby's genitals. If it is necessary to stimulate urination, feed the baby with a breast or a mixture from a bottle, drink him with water, do light strokes along the back of the baby.

2. If you do not have a urine bag for children, you can use a plate. Wash it with baking soda in advance and dry well. Gently bring her under the baby's ass at a crucial moment.

3. Another option is to use a new polyethylene bag with handles. Attach them to your baby's thighs, and then immediately pour the collected urine into the prepared container.

Before you start collecting your baby's urine, be sure to wash it off with warm water without soap.

If a breastfed baby is breastfed, mom should adhere to the same food and drug restrictions as given for adult patients.

Rules for collecting urine analysis from a child

When a child reaches the age of two, he already understands what his parents want from him, and independently controls his needs. Therefore, collecting urine for analysis even from such a crumb is not a big deal for parents.

Moreover, if you show your imagination and turn the process itself into a game, then the crumb will gladly help you achieve the desired result. Do not skimp on praise and encouragement, and then with little children there will be no serious problems when you need to collect urine for analysis.

The procedure is the same:

  1. Obligatory hygiene procedures: genital lavage immediately before urine collection.
  2. Encourage your child to pee in a wide dish prepared in advance. Do not use a pot for this, as non-sterile containers may contain pathogenic bacteria, whose vital activity decomposes urine.
  3. Stir the contents and pour out the desired volume - about 100 ml. - in a sterile container or jar with a marker pasted on it indicating the name of the patient and the attending physician.
  4. You can store urine before analysis for no more than five hours only in the refrigerator, but it is much more correct to immediately send it to the laboratory for research.

We must not forget that a two-three-year-old child is still small enough to be able to restrain his urge to use the toilet for some time, so all hygiene procedures should be done as quickly as possible.

As you can see, collecting urine for general analysis is a fairly simple procedure that does not require excessive knowledge and complex preparation. It is enough just to adhere to some dietary recommendations and not ignore the obligatory morning hygiene procedures.
