What does a urine test detect in a physical examination What can a urine test detect?

During the physical examination, the urine routine examination can understand the concentration and dilution function of the kidneys, as well as the acid-base regulation function, and can also understand whether there is infection and bleeding. The routine examination includes the following items: 1. Urine pH value, which can understand the pH change of urine.

2. The number of white blood cells in the urine, if the number of white blood cells increases, it indirectly indicates that there is an infection in the urinary tract. 3. The number of red blood cells in the urine, if the number of red blood cells increases, it indicates that there is bleeding in the urinary system, and the cause of bleeding needs to be further examined. 4. The specific gravity of urine can understand whether there is urine dilution or urine concentration.

5. Urine bilirubin, which can know whether bilirubin is elevated and whether there is a systemic bilirubin metabolism disorder. 6. Nitrite in urine, when there is an infection in the urine, especially when the infection caused by Enterobacteriaceae is present, nitrite can be reduced to positive, which indirectly indicates the presence of Enterobacteriaceae infection in the urine. 7. Protein, when the protein in the urine is elevated, it may be related to infection or kidney damage, and further measurement of urine protein is needed to rule out kidney damage.

Urine can reflect the health of the human body, and here are some ways to focus on your physical health through urine:

1.Check the color of your urine: If the urine is yellowish, it may be caused by a lack of sakura water, and if it is red or brown, it may be caused by a disease such as kidney disease.

2.Check the smell of your urine: If your urine has a pungent smell, it may be caused by an infection or other health problem.

3.Check the clarity of your urine: Clear urine usually means good health, and if there is sediment or cloudiness, it may be an infection or other health problem that is causing the spine or more.

4.Check the pH of the urine: The pH of the urine is usually between 5 and 9, and if it exceeds this range, it may be caused by some pathological conditions.

5.Check your urine for protein, glucose, ketones and more: These can help detect diabetes, kidney disease, and other health problems.

In conclusion, paying attention to urine can help you detect health problems and do them early**, but it is important to note that these indicators are not the only basis for diagnosing diseases, and it is best to maintain your health in combination with the advice and examinations of a professional doctor.

Generally speaking, during the physical examination of employment, the urine test is a urine routine. The urine routine examination mainly includes urine color, urine transparency, red blood cells, white blood cells, bacteria, casts, yeast, crystals, epithelial cells, urobilinogen, urine bilirubin, urine ketones, urine protein, nitrite, urine occult blood, urine glucose, urine specific gravity, urine pH value and other items. If the patient has abnormal urinalysis, further tests may be required under the guidance of a physician to evaluate the condition and determine the cause for more targeting**.

Urine tests include pH, protein, ketones, glucose, white blood cells, red blood cells, etc., mainly to check the urinary system, such as: urinary tract infection, bleeding, diabetes, etc.

The experts of the People's Physical Examination Center will explain to you:

Urine leukocyte test:

Most of the white blood cells in the urine are neutrophils that occur during inflammation and infection. It has undergone degenerative changes, irregular morphology, vague structure, and can also be called pus cells, which are acute and chronic pyelonephritis, cystitis and other urinary tract infections.

Nitrite test:

Some bacteria present in the urinary system can reduce the protein metabolite nitrate in the urine to nitrite. Therefore, measuring the presence of nitrite in the urine can quickly tell the status of urinary bacterial infections.

Glucose (Glu) test:

Healthy people have very little glucose in their urine, and almost all the glucose in their urine is absorbed by the kidneys. Diabetes usually refers to the excretion of glucose in the urine at 150 mg per day. The level of blood sugar determines the presence or absence of glucose in the urine. At the same time, it should be noted that in pregnant women and some renal tubular or renal interstitial lesions, the renal glucose threshold is lowered, and diabetes can also occur when blood glucose is normal. In addition to the interference of renal glucose threshold and some reducing substances, the influencing factors of urine glucose are often affected by the amount of urine and the emptying of the bladder.

Proteinuria test: Usually, healthy people show a negative urine protein index on a routine urinalysis, i.e., (). If the proteinuria item on the urine test is indicated, the body is normal.

If the urine test is positive, such as proteinuria+, proteinuria++, proteinuria+++, it means that the kidneys are abnormal. Urine protein +++ indicates the amount of protein in the urine, generally speaking, the more + the more protein is leaked from the kidneys, but in the case of pathology, the more + the more severe the disease, the statement is not valid.

The urine test is mainly checked: specific gravity, pH normal value, white blood cells, nitrate, urine protein, urine glucose, ketone body, urobililin, bilirubin and other routine tests. Urine sedimentoscopy and urinalysis are done. It is also to see if there is any infection of the urethra, nephritis, nephrotic syndrome and early pregnancy.

Urine routine examination is one of the most commonly used tests in hospitals, and it is one of the basic indicators to reflect the health status of the body. Urine routine examination can be carried out in hospitals and laboratories at all levels, and it is the most simple, easy, painful and rapid examination method.

In many cases, doctors often ask patients to go for urine routine tests, and require patients to frequently review the results of urine routine tests, the purpose of which is to understand the general condition and changes of the kidneys, whether diseases of other organs have an impact on kidney function, whether drugs have an effect on the kidneys, and observe the effect of **. Therefore, urinalysis is an indicator that needs to be observed frequently.

Urine routine examination should generally include urine protein qualitative, urine glucose qualitative and urine sediment examination. Nowadays, because many hospitals use semi-automatic or automatic urine analyzers, the urine routine results can provide 8 to 10 measurement data at the same time, which generally include urine protein, urine glucose, urine ketone body, urine specific gravity, pH, urine bilirubin, urine bilinogen, nitrite, red blood cells (occult blood) and white blood cells. Individual instruments also include qualitative tests to rule out vitamin interference in the urine.

Urine test can detect some lesions of the urinary system and related organs, such as nephritis, stones, diabetes, bacteriuria, etc., and can also detect early pregnancy.

Red and white blood cell proteins, urine glycoketone bodies.
