Is it necessary to have morning urine for routine urine test

Many people go to the hospital for a routine urine test for the first time and do not have much experience and knowledge, so they do not understand whether they must use the first urination in the morning. For a routine urine test, it is best to use fresh morning urine, which will be more likely to detect some problems in the body. In addition, there are many things to note about routine urine tests.

Urinalysis precautions

The first thing to note in a routine urine test is that fresh morning urine should be used as a urine sample. Because people drink less water at night, the various components excreted into the urine by the kidneys are stored in the bladder and concentrated, making them easy to detect, thereby increasing the positive detection rate. Other randomly collected urine samples are also acceptable, but midstream urine should be collected as much as possible.

Urinalysis precautions:

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

2. Women are generally required to avoid collecting urine samples during their menstrual period to prevent vaginal secretions from mixing into the urine and affecting the test results.

3. It is best to collect midstream urine.

Many kidney patients have asked why they should consciously collect midstream urine during routine urine tests? According to the order of urination, urine can be divided into the front section, middle section and back section. Because the first and second stream urine are easily contaminated, midstream urine is generally collected when doing urine routine and urine bacteriological examinations.

4. Urine should be collected in clean and dry containers, such as the disposable urine cup and urine test tube 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 decomposed by bacteria, tubular destruction, and cell lysis may occur, affecting the accuracy of the test 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 urine test results.

Precautions for routine urine microscopy

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 pyuria will disappear.

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

3. In patients with urinary tract infection, pyuria is often intermittent, so repeated examinations are necessary before a conclusion can be drawn.

4. The use of antibiotics may affect the accuracy of the examination.

Precautions for routine urine examination in children

Urine should be collected in clean containers, which will be provided by professional medical examination institutions. The amount of retained urine is generally around 20 ml, preferably the first urine in the morning, and it is best to send it for testing within 30-60 minutes. When girls retain urine, they should first clean the perineum to avoid mixing it with feces, and should avoid the menstrual period to prevent mixing with other secretions. When doing urine culture, you should keep the midstream urine, that is, discard the first section and collect the middle section of urine.
