Urine analysis of the tank sowing (bacteriological urine culture) is a laboratory examination of the urine aimed at identifying the pathogen and at determining the level of bacteriuria when the infection is entered into the urinary system. Aerobic bacteria are identified by determining the threshold of sensitivity to the active components of antibiotics.
Doctors can prescribe urine bacillus for patients who have recently been infected and for patients with a relapsing course of the disease.
The main disadvantage of the method is its excessive duration and increased demands on the material intake. However, bacteriological urine culture allows the doctor to obtain unique data that are not determined by any other study.
What is a sowing tank, and what is it for?
Buck sowing - urine analysis, which implies the use of it as a laboratory material to grow bacteria in the urine. The study is conducted at a certain temperature and in compliance with medical standards and norms.
This type of research is assigned to determine which microbes are in the focus from which the material was taken for the study, and also to determine whether there are pathogenic microbes and how many of them are.
Buck seeding on the flora and sensitivity to antibiotics makes it possible to determine also to which drugs the microbes are susceptible, which makes it possible to conduct the most effective treatment.
How to collect urine on the tank sowing?
On the eve of such a procedure, it is strongly recommended to abandon the consumption of vegetables, as well as fruits, which are capable of changing the color of urine. These include carrots, beets and some others. Also, you can not drink any diuretic drugs. Such studies should not be carried out by women at the menstruation stage.
To protect the urine sample from microorganisms that are on the mucous membrane, you must follow certain rules:
- The material for analysis should be collected only in a sterile container, approximately half of the morning urine will be needed, with the first portion going to the toilet and the rest to the container. Hygiene of the external genital organs will have to be carried out in advance.
- In order to obtain the most accurate result, the urine collected for analysis should be submitted to the laboratory no later than an hour after collection.
Approximately three weeks later, after the completion of the prescribed medication, the patient is advised to retake the urine sowing tank to determine how effective the treatment has been.
Price and terms
Many people are interested in how many days analysis is done on the tank sowing. It is impossible to answer this question unequivocally, it all depends on what material is being studied and what pathogen is to be found. Sometimes the answer is ready in 3 days, sometimes in 1-2 weeks, because some samples require reseeding on another medium.
The approximate cost of this urine test in Moscow is about 800 - 1500 rubles.
Deciphering the analysis of urine urine
CFU is one microbial cell (or group). The development of a colony of microorganisms is characterized in these units. For example, indicators of 1000 CFU / ml indicate that microorganisms accidentally got into the intake material from the external genitalia. In this case, nothing needs to be treated.
When a laboratory study exceeds the concentration of 100,000 CFU / ml, then we can talk about the connection of inflammation with the infection. With an intermediate result of 1000-10,000 CFU / ml, the urine analysis for bacposa is in doubt, and a re-examination is required.
If the analysis is positive, the microorganisms found are listed in the conclusion: bacteria, fungi, protozoa, etc. After the final decoding of bacteriological urine culture, both additional tests and the final course of treatment are prescribed.
Tank urine culture during pregnancy
Urine analysis of the tank sowing during pregnancy is usually carried out twice: the first - when registering for pregnancy, the second - almost before the delivery process, at week 36.
In cases when leucocytes or protein were found as a result of deciphering the general urine analysis, urine analysis on the seeding tank can be carried out more often in order to establish the sensitivity of pathogenic microorganisms to prescribed antibacterial drugs. In addition, if the treatment of urological infections is carried out, such a study is conducted 7 days after the cancellation of the prescribed antibiotics.
To properly pass the urine on the tank sowing is necessary:
- Purchase a sterile container and collect the first morning urine in it, after having been thoroughly washed.
- When the biomaterial is selected, you must carefully close the container with a lid and take the sample to the laboratory for research as quickly as possible, preferably within 2 hours.
Regardless of the price of this analysis, you definitely need to carry it out in order to prevent possible illnesses, save pregnancy, do not harm the fetus and prevent illnesses that in the future can cost not only more expensive, but also more difficult to treat.
