Daily urinalysis is a simple but very informative diagnostic method. It helps to identify many pathological changes in the human body. But in order for the results to be as accurate as possible, the patient must know how to collect daily urine. Urine is an aqueous solution of substances such as urea, creatine, sodium, potassium, and others. In the secretions of a he althy person, they contain a certain amount. If the results of the daily analysis give other indicators, this indicates the development of pathologies. Basically, this study is prescribed to assess the excretory and metabolic function of the kidneys.
Factors affecting analysis accuracy
In order to prepare material for research, you need to know how to properly collect daily urine. Firstly, you need to collect only the liquid that was released within the daily period. That is, the material assumes the presence of the entire volume of urine per day, and no more. Secondly, spills should not be allowed, since this entails the loss of part of the information. Thirdly,improper storage of the material for analysis causes the passage of chemical reactions in it, and, as a result, incorrect result data are possible. Fourth, the use of medications and certain foods makes urine unsuitable for establishing neutral body parameters.
Indications for daily urinalysis
This study is prescribed by a doctor to identify many indicators. Most often, the presence and mass of the following substances are established: protein, glucose, oxalates and metanephrines. Since quantitative indicators are also established in the study, the patient must know exactly how to collect a daily urine test. Identification of protein in the material is necessary for diabetes mellitus, the threat of coronary heart disease, nephropathy and chronic renal failure, as well as when taking certain drugs. The detection of glucose in the urine is prescribed for the diagnosis of diabetes mellitus, pathology of the adrenal glands and thyroid gland, pancreatic tumors and pancreatitis. Metanephrines are detected in diseases of the adrenal glands, oxalates in diabetes mellitus, renal failure, urolithiasis and other diseases.
Before material collection
No special preparation is required to collect the excreted fluid. However, before collecting daily urine, the following steps are necessary. You must tell the doctor after the appointment of the analysis, whichmedications you are taking, including vitamins. Women who are pregnant should also inform their he althcare professional. Your doctor may need to make some adjustments to your diet and medication. For the event, select the day you are at home so you don't lose material.
Collecting material for research
The doctor at the reception will tell you how to collect daily urine, but you can still remind. If you decide to start collecting material in the morning, then in the evening prepare a container in which the liquid will be stored in a cool place. Also prepare a vessel in which you will collect urine. The first portion (if it is morning) should not be saved, but you need to fix the time. It is at this hour the next day that you will complete the collection of material. All urine should be collected and poured into a container, which should be stored at a temperature of +6 to +8 degrees. Also, before collecting daily urine, it is necessary to determine the drinking regime for this time - from 1.5 to 2 liters. Deliver the material to the laboratory as soon as the material is collected.
