That is why it is important to know how to properly collect a complete urinalysis, so that a specialist can get the most reliable, not distorted information about the condition and functioning of organs.
Experts say that taking the urine to the laboratory to study its properties once a year is useful for all patients, regardless of gender and age. This helps to identify the slightest deviations or the development of any pathological processes in the kidneys and bladder. Chemical study of the properties of urine allows you to identify some serious diseases at their initial stage. These include:
- various diseases provoked by metabolic disorders.
During treatment, urinalysis is required to pass more often. This helps to track the effectiveness of the drugs taken by the patient.
How to properly collect urine for general analysis?
It is important for each doctor to get correct, not distorted research results, therefore they recommend to follow certain rules:
- immediately before collecting the analysis, avoid eating fruits, vegetables of red and yellow color, changing the color of urine, as well as highly carbonated beverages with preservatives and artificial dyes, citrus and vegetable juices;
- avoid excessive consumption of products exhibiting a diuretic effect, and medical drugs with a similar effect;

Urine analysis collected in the morning, immediately after sleep. Allowed 2 ways to collect urine.
Method number 1
In a sterile container for analysis (you can buy it at any pharmacy) all the quantity of morning urine is collected. Next, all you need to shake up and pour out excess liquid, leaving about 100 ml. This amount is quite enough for analysis.
Method number 2
This is the most common option when a small amount of urine is flushed down the toilet, then a sterile container is inserted and filled in about half. Then the container is tightly sealed and handed over.
In many cases, a specialist can reassign urine delivery for microscopic analysis due to high protein and white blood cell counts.
Features of collecting biomaterials from adults
How to properly collect a general urine test in adults? Immediately before collecting urine, it is imperative that you thoroughly wash your genitals with soap and wipe dry after washing.
During urination, women need to maximally dissolve the labia toes, so that the liquid immediately from the urethra falls into the container without washing them.

Therefore, the urine for analysis is collected in the early morning, after sleep, following all hygienic rules.
When urinating, men should completely remove the foreskin of the penis so that urine immediately falls into the container. Then the results will be as reliable as possible and will not show an excessive number of leukocytes.
Parents for a note
Children in the period up to a year have to pass urine for a general analysis every 3 months. After a year, this type of analysis is done less frequently.

How to store collected urine?
Urine for general analysis can not be collected in advance. It should be delivered to a medical facility for diagnosis within 1.5 hours after collection. Otherwise, irreversible changes in physical and chemical properties begin to occur in the fluid: the cells are destroyed, bacteria begin to multiply. These factors adversely affect the overall picture of the analysis.
Transportation analysis should be carried out in an airtight plastic container, tightly wrapped in a plastic bag. As for the air temperature, there are no uniform violations of the elements during cooling, provided that the analysis will be delivered to the medical institution for the appropriate period.
Even Hippocrates in 400 BC, when there was no laboratory research, could tell what a person is sick with, what the severity of the disease is, only on one physical properties of urine. With various ailments, it changes its color, transparency and acidity. That is why it is very important to know how to collect a general analysis of urine so that the fluid does not change its physical and chemical properties.
