A three-glass urine test is necessary in order to determine in which part of the genitourinary system the focus of inflammation is located. Urine for this study needs to be collected in a special way. Next, a microscopic examination of the collected material is carried out.
In what cases is this type of study prescribed to the patient?
In the process of diagnosis, patients first pass a general analysis. If the samples have an increased level of leukocytes, then a person is prescribed an analysis according to Nechiporenko.
Sometimes a laboratory test confirms that the level of leukocytes in the urine samples is higher than normal. Such results indicate that in the human body there is an inflammatory process that covers the tissues of the genitourinary system.
To determine the exact location of the process, a three-glass urine sample is taken. And how exactly should it be collected? Now we will tell.
We collect urine correctly
What to do if you are prescribed a three-glass urine sample? How to collect material?
- First of all, the patient must refrain from urinating before delivering the material for three hours.
- Just before the fence you should wash yourself. This procedure is carried out without the use of soap, only through warm water.
- Urine is collected in 3 containers, and the containers are filled in different volumes. 1/5 of the urine is collected in the first container (first portion). The second container should be filled 3/5. In the last container, one fifth remains.
- If this urinalysis is prescribed by a doctor to confirm the diagnosis of prostatitis, then the patient needs prostate massage before collecting material for the third container.
- The resulting material must be brought to the laboratory as soon as possible for the study.
Decryption
How is the decryption of such an analysis? What does the doctor pay attention to?
- If there is an increase in the level of leukocytes in the first portion of the donated material, but in the other two not, then this indicates a pathology in the urethra.
- In the case when this indicator is increased in the third container, and in the first two it is normal, we can conclude that the patient has prostatitis.
- When white blood cells are present in large numbers in all three containers, this is a sign that the patient is developing inflammatory diseases of the kidneys or bladder.
- There are cases when the level of leukocytes is higher than normal in the first and third container, and in the second their level is normal. This means that the patient has an inflamed prostate and urethra.
How is the study going?
What is microscopic examination? First, the urine is centrifuged. Next, the resulting precipitate is examined through a microscope. Urine sediment is considered a ten-fold or forty-fold increase. What does it mean? A ten-fold increase is considered small, and a forty-fold increase is considered large. In samples, a specialist can see such structures as:
- Red blood cells.
- White blood cells.
- Epithelial cells.
- Bacteria.
- Protein.
- Salt.
Which container should be used?
Now in any pharmacy you can buy a container for collecting urine. This container is made of special material. It is absolutely neutral with respect to any substances, does not enter into a chemical reaction with laboratory samples.
There are two types of material from which containers are made:
- Ultra-pure polypropylene.
- Polystyrene for medical use.
The urine collection container is equipped with a special screw cap. It provides protection of the collected material from environmental influences. Also, the cap allows you to easily deliver the analysis to the laboratory for research. Containers may have different volumes. Depending on the type of study, you should choose the right size.
Analysis Tips
A day before collecting material for research, it is not recommended to eat:
- Fruits, namely citrus fruits and watermelon.
- Vegetables such as beets and carrots.
- Vitamins, if they can affect the color change of urine.
- Diuretic drugs.
- Red wine.
- Beer.
Women should refrain from taking a urine test if they have menstruation.
If a person takes any medications, then you must definitely tell the doctor about it. It should be understood that medication is reflected in the results of the analysis. Immediately before collecting the material, namely in a couple of hours, you can not drink coffee and smoke.
The containers to be used for urine should be numbered. This is necessary so as not to confuse them with each other.
Also, before passing the analysis, the patient should avoid stress. With overexcitation or nervous shock in a person, the hormonal background changes dramatically and protein often rises in the urine.
Conclusion
Now you know what a three-glass urine sample is. As you can see, this study is a unique way to identify in which area of โโthe urethra the inflammatory process develops. In our article, we made recommendations that will help you pass the analysis correctly.
