If you have noticed, the surrender of urine for laboratory research is a mandatory procedure for any comprehensive diagnosis. The result of this analysis allows you to identify various ailments. So, in order to check the functioning of the kidneys and urinary system as a whole, doctors are prescribed a urine analysis according to Zimnitsky.
Anamnesis samples Zimnitsky
Many people who are faced with the surrender of urine for laboratory research, referred to in practice as the Zimnitsky breakdown, often wonder what such a diagnosis shows. Urinalysis according to Zimnitsky allows you to get a full clinical picture of the functioning of the kidneys throughout the day. The doctor will be able not only to diagnose the ailments of the urinary system, but also to evaluate the work of the kidneys, which play a dominant role in filtering harmful components and in removing them from the body in the form of urine.
Zimnitsky's test may be appointed by a specialized doctor if there is a suspicion of the development of pathologies of the urinary system, in particular:
- chronic ailments;
- renal failure;
This analysis of urine allows the doctor to assess the functioning of the kidneys hourly. In the urine samples provided for the comparative study, its density, concentration, etc. is determined. It is very important for people suffering from diabetes to take a Zimnitsky sample, since an increased concentration of sugar in the blood adversely affects the functioning of all internal organs. And the kidneys are no exception.
The analysis of urine in Zimnitsky in children is carried out in order to identify the following ailments:
- renal failure;
- heart failure;
Take care of a reliable result of the study
In order for the results of the urine study to be reliable and as accurate as possible, you need to know how to collect comparative samples for urinalysis according to Zimnitsky. The uniqueness and accuracy of this method of diagnosis lies in its multi-stage. Urine should be taken during the day at a certain time. Immediately make a reservation that there are no restrictions in the diet or drinking regime.
To prepare for the sample Zimnitsky you need the following materials:
- 8 urine collection containers;
- alarm clock;
- chart paper.
Urine is taken every three hours. The first trip to the toilet should take place at six in the morning. This urine is not suitable for comparative studies, since it is considered to be nocturnal. The doctor is only interested in the material that you will collect during the day. As you know, it is during wakefulness that our kidneys actively filter out harmful substances and produce urine. The amount of daily value of urine is about 75%. The rest falls on night urine.
The first urine is taken at nine o'clock. Then, at regular intervals, another 7 urine fences are carried out, that is, at 12, 15, 18, 21, 24, 3, 6 hours. In the graph, it is necessary to display all the liquid consumed for that day. This applies not only to pure water, but also to any drinks, dairy products, etc. To obtain reliable results, it is advisable to indicate the time and volume of fluid intake in the schedule.
Each container filled with urine is stored in a refrigerating chamber until it is delivered to the laboratory. What if there is no urge to urinate by the set time? In this case, you leave the jar empty, and make a corresponding mark in the chart.
Often in practice there are such cases when a person feels the urge to emit urine more often than once every three hours. In this case, the patient needs to use additional containers and perform the collection of urine. This is also marked in the schedule, which is provided to the laboratory along with comparative samples for the study according to the Zimnitsky method.
Everyone knows that it is almost impossible to decipher test results encoded in accordance with medical terminology. One handwriting is worth it. But it is still possible to try to understand the result of the analysis before the visit to the relevant doctor.
Decoding of urine analysis for Zimnitsky we will now spend together. As practice shows, many people are primarily interested in the norm. So, the following parameters are considered normal indicators of urine analysis in Zimnitsky:
- the volume of urine during the day varies from 1500 to 2000 ml;
- the ratio of fluid consumed to the excreted urine within 24 hours ranges from 65 to 80%;
- during the daytime, the amount of urine excreted is 2/3 parts, and at night - 1/3;
- urine density normally ranges from 1003 to 1035 g / mol.
Also, the laboratory technician calculates the density level in the aggregate and in each tank separately. Be sure to display its average. An important indicator for the norm experts believe the increased urge to urinate after drinking a certain amount of fluid.
Let's talk about deviations from the norm
What indicators will tell about the violation in the functioning of the kidneys and the presence of pathology? With a low level of urine density, doctors diagnose hypostenuria. This may indicate the progression of pyelonephritis in the relapse stage, as well as heart failure caused by the development of chronic ailments. A low level of urine density is also observed in cases of kidney damage with non-heavy metal compounds.
Often in practice there are cases when the test results for Zimnitsky are characterized by a high level of urine density. Then we are talking about hyperstenuria. Such indicators most often characterize the development of the following ailments:
This indicator may also be overestimated if the woman is pregnant and she has toxicosis. The analysis of urine in Zimnitsky during pregnancy is carried out quite often in order to diagnose any illnesses of the urinary system organs in a timely manner. As is known, against the background of changes in the hormonal level, the internal organs are subjected to a grueling and uncharacteristic load.
Pyelonephritis or other renal diseases - this is not the best combination for a happy and cloudless pregnancy. In these cases, the woman throughout the entire period of gestation is under the close supervision of a specialized doctor.
On the development of diabetes mellitus or the progression of renal failure will also tell an increased amount of output urine in one day. As a rule, polyuria is diagnosed if the amount of excreted urine is 80% relative to the volume of fluid consumed.
In conclusion, the laboratory can be diagnosed oliguria. What does this mean? This term refers to the condition when the amount of urine released per day is significantly underestimated. As a rule, this condition is observed in violation of the filtration function of the kidneys. Based on these results, the doctor can diagnose one of the following ailments:
- renal failure;
- mushroom poisoning;
- heart failure;
- global destruction of red blood cells.
Some people suffer from nocturia. This term is used in medical practice to state when the amount of urine released at night significantly exceeds 1/3 of the daily norm. Most often, this disorder affects people with diabetes.
The Zimnitsky test today is considered an affordable, fast, inexpensive and accurate diagnostic method. It is through such an analysis that the functioning of the kidneys and other organs of the urinary system can be fully evaluated. And in order for the clinical picture to be reliable, it is necessary to follow all the rules of urine collection for laboratory testing. Be healthy!
