What does a male urine test test?

Urine test is the most basic physical examination. The application of urine routine in clinical practice is very extensive. We can often judge many hidden diseases through urine routine examination. However, many people are confused when doing urine routine examination and do not know what they have checked. So what does a man's urine test check? Let's talk about some indicators of urine routine examination.

Indicators of bacterial urinary tract infection.

Qualitative test: Negative

Abnormalities indicate the possibility of a urinary tract infection.

Urinary nitrite (NIT)

Screening indicators for bacterial urinary tract infection.

Qualitative test: Negative

Urine protein qualitative (PRO)

Urine protein examination is an important indicator for the diagnosis, treatment and prognosis of kidney diseases.

Qualitative test: Negative

Precautions for routine urine tests: The first thing to note is that urine specimens should generally be fresh morning urine, as much as possible. Because people drink less water at night, many components excreted into urine by the kidneys are stored in the bladder and concentrated, making them easy to detect, thus increasing the positive detection rate. Other randomly collected urine can also be used, but midstream urine should be collected as much as possible.

1. During routine urine examination, collect no less than 10 ml of urine.

2. Women are generally required to avoid menstruation when collecting urine samples to prevent vaginal secretions from mixing into the urine and affecting the test results.

3. It is better to collect midstream urine. Many kidney disease patients have asked why they should consciously collect midstream urine in routine urine examination? According to the order of urination, urine can be divided into front urine, middle urine and back urine. Because front urine and back urine are easily contaminated, midstream urine is generally collected when doing routine urine examination and urine bacteriology examination.

4. Urine should be collected in clean and dry containers, such as disposable urine cups and urine test tubes provided by the hospital.

5. The retained urine should be sent to the laboratory for examination as soon as possible, because if it is left for too long, problems such as glucose being broken down by bacteria, destruction of casts, and cell lysis may occur, which will affect the accuracy of the examination results.

Therefore, when doing a routine urine test, paying attention to the correct standards for collecting urine samples is the key to ensuring the accuracy of the routine urine test results.

1. The urine sample must be fresh. Otherwise, after being left for a few hours, the red blood cells and white blood cells may be destroyed and the purulent urine may disappear.

2. The urine sample must be clean. Women should wash their vulva to avoid mixing leucorrhea. If there are a large number of polygonal epithelial cells in the urine sediment, it may have been mixed with leucorrhea. It is advisable to collect a clean urine sample for re-examination.

3. Patients with urinary tract infection often have intermittent urine purulent urine, so it is necessary to conduct repeated examinations before reaching a conclusion.

4. The use of antibacterial drugs may affect the accuracy of the examination.

Precautions for routine urine examination in children

Urine should be collected in a clean container, which will be provided by professional medical examination institutions. The amount of retained urine is generally about 20 ml, preferably the first urine in the morning, and it is best to send it for examination within 30-60 minutes. Girls should first clean the perineum when retaining urine, do not mix it with feces, and avoid the menstrual period to prevent other secretions from mixing in.

When doing urine culture, you should keep the midstream urine, that is, discard the first part of the urine and collect the middle part of the urine.

When measuring pus and blood, and when taking alkaline drugs such as soda, the urine becomes alkaline and the pH rises.
