Most often, at the first visit to the doctor, the doctor gives the patient directions for certain tests. This is usually a general blood and urine test. After receiving the first results, additional diagnostics may be recommended. This includes urine analysis according to Nechiporenko, Zimnitsky's test, bacteriological sowing of the material, and so on. All these studies will allow you to more fully understand the work of the patient. This article will tell you about the rules for collecting urine according to Zimnitsky (algorithm). You can learn about the essence of this analysis and find out the features of its implementation. You will also understand whether the collection of urine tests in Zimnitsky can take place without prior preparation.
What is the study done for?
The technique of collecting urine in Zimnitsky will be described a little later. To begin with, it is worth mentioning the essence of the study. Diagnostics are prescribed to patients who suspected a violation of the kidneys and excretory system. Also, the analysis can be recommended to expectant mothers when registering for pregnancy.
Diagnosis allows you to identify substances that are excreted by the human body during urination. In addition, the density of the liquid and its total amount are determined. An important role is played by color and the presence of sediment.
Urine collection algorithm for Zimnitsky
If such a study is recommended to you, then you should definitely check with the doctor all the nuances. Otherwise, you will not be able to properly prepare, and the technique for collecting urine in Zimnitsky will be violated.
The algorithm includes preparation for diagnosis. After observing certain conditions, it is necessary to choose the dishes correctly, collect the allocated liquid and store it at the right temperature. It is necessary to deliver the analysis to the laboratory at a time strictly agreed with the specialist. How is urine collected in Zimnitsky? The algorithm of actions will be presented to you further.
The first step: preparing the body
The algorithm for collecting urine according to Zimnitsky involves preliminary preparation of the body and compliance with certain rules. Before collecting material, you should refrain from drinking alcohol and fatty foods.
Also, excessive intake of fluids and diuretics can distort the diagnostic result. Products such as watermelon, melon and grapes should be excluded from the diet at least a day before the material is taken.
Second step: preparing the container
The next paragraph, which describes the algorithm for collecting urine according to Zimnitsky, involves the preparation of special sterile containers. Of course, you can use your own food containers. However, in this case, they must be thoroughly sterilized. Otherwise, the result may be false. Remember that the collected material will remain in the container for more than one hour. The number of servings needed is usually eight.
Doctors recommend purchasing special containers for collecting tests. They are sold in every pharmacy chain or large supermarkets and cost about 10-20 rubles. Give preference to capacities from 200 to 500 milliliters. If necessary, buy larger glasses. These jars are already sterile and do not require additional processing. They must be opened immediately before the material is taken.
Third step: scheduling toilet trips
The next item, which is reported by the Zimnitsky urine collection algorithm, talks about the need to compile a list of time intervals. So, the patient needs to empty the bladder 8 times a day. The most suitable time is 9, 12, 15, 18, 21, 00, 3 and 6 hours. However, you can choose a schedule that is convenient for you. Remember that the interval between going to the toilet should be no less than no more than three hours. Otherwise, the portion of the material may be increased or decreased. This will lead to a distortion of the results and an incorrect diagnosis. The whole day should be divided into eight equal parts. With a simple count, you can find out that you need to urinate in three hours.
The fourth step: good hygiene
The technique of collecting urine according to Zimnitsky (algorithm) involves the preliminary conduct of hygiene procedures. Only in this case the result will be correct. If you ignore this item in the material can be detected by impurities and bacteria. This will give a poor result of the study.
Be sure to wash your hands with soap before taking urine. To do this, it is better to use antibacterial cleaners. You also need to hold the toilet of the genitals. Men just need to wash their penis. Women, in addition to washing, need to insert a cotton swab into the vagina. Otherwise, the flora of the reproductive system may be moved by the flow of urine into a sterile container. The result of the analysis will be distorted and will be unreliable.
Fifth step: collecting urine
After the hygiene procedures, you need to start collecting material. Collect in the prepared container the whole portion of urine at certain hours. After this, the container must be signed, indicating the time on it.
Some patients use a single collection container. After that, material is poured out of it over the prepared containers. It is worth noting that this can not be done. A similar technique can lead to the development of bacteria and the formation of sediment on the stand-up cup. Collect urine directly into pre-prepared containers. Then tighten the container tightly with the included lid. It is strictly forbidden to open and overfill the collected fluid.
Sixth step: storage of material and method of delivery to the laboratory
After the first container is full, it must be refrigerated. It is forbidden to store the test material at room temperature or in the freezer. The most optimal degree of the environment is in the range from 2 to 10. If it is warmer, microorganisms will begin to develop in the urine. In this case, an incorrect diagnosis of bacteriuria may be made.
The material must be delivered to the laboratory the next morning, when the last fluid intake will be made. In this case, it is necessary to ensure that all containers are tightly closed and signed. If there is a loss of fluid from any cup, you should definitely inform the laboratory assistant. Otherwise, the result may be distorted, since the density of the studied material will change.
Zimnitsky urine collection in children: algorithm
What to do if such a study needs to be carried out in a child? Most children can not tolerate another urge to urinate and do not comply with the described regimen. What to do in this case? First of all, you need to consult a doctor. The medic will tell you the basic methods of action. In most cases, it is recommended to adhere to the following scheme:
- prepare sterile jars;
- wash your child before each trip to the toilet;
- collect urine in a container and observe the above storage conditions;
- if you urge to empty the bladder before the prescribed time, fix it on a sterile container;
- Deliver the material to the laboratory for research.
What to do if the collection of material is necessary for an infant or a newborn baby? In most cases, doctors use other methods to diagnose the condition of the crumbs. It is practically impossible to collect urine for the Zimnitsky test. However, in case of urgent need for such a diagnosis, pediatricians recommend the use of special urinals. They are absolutely sterile and very comfortable. The device has an adhesive surface and is superimposed on the genitals of the baby. After urination, the fluid is collected in a sterile container, taking into account all the above conditions. Next, you need to glue a new bag for collecting tests and wait until the crumbs express a desire to empty the bladder.
Summing up the article
You became aware of the conditions that urine collection in Zimnitsky implies. The algorithm is pretty simple. It is only necessary to strictly adhere to the points described. Most doctors recommend that patients set alarms for a specific time. In this case, you will not be afraid that you missed the right time to urinate. At night, you just can not do without a special alert. Normally, a person is in a state of sleep for 8-12 hours and does not feel a natural desire to empty the bladder.
When receiving directions to such a study, be sure to check all the nuances of the doctor. Remember that the dishes must be sterile and the storage conditions of the material are correct. Collect urine according to Zimnitsky taking into account the described algorithm. Good research results!
