Urine examination because to stay with convenient, fast, has become a daily health observation and early secondary diagnosis of a routine examination, through which you can observe people's kidneys and gallbladder, urology, and other aspects of the situation, but many people are wondering about the reliability of urine check.
Several people said: "since the urine check so widespread, and that seem very scientific, why I checked it out yesterday and today's results are not the same as?", a copy of the inspection report, sometimes patients "look" was to cry after the pessimistic, but doctors have said that "look".
Armed Police Corps Hospital Director of Guangdong Province in Joel Yongmei and Urology Wang Jianping doctors believe, if only partial, rigid enough to believe that the conclusions on the checklist, and not combine their other conditions, the "snake", he scared myself.
The sudden increase in red blood cells?
Women's menstrual period results unreliable
RBC sediment reference range is 0 ~ 2/HP, but often there are patients with goes out of scope of a single doctor, worried about their own "renal bleeding or bleeding" under the urethra, and the fact that many women check after all is excluded because of their "conclusions" is based on the period of ineligibility, unreliable.
"Women's urine is often mixed with vaginal discharge, the sudden increase in red blood cells, in fact, most likely because legitimate vacation.
"Hora Yongmei agent normal extraction in urine, blood is very important" test object ".
Joel Yongmei agent masters say that female menstrual period or height must not do urine check, because this time of red cell morphology is damaged, and the number also changes.
In addition, holding back urine also will significantly undermine the RBC morphology, and urine PH value has changed.
Increased urinary protein?
You may drink too much milk's sake
"Do you think this case detection, the above negative urine protein shows patients this check to belong to a healthy state, but protein is very easy to fluctuations, sometimes shows positive nor the patient must be treated.
"Police hospital Urology Wang Jianping doctor said, proteinuria is a" lively ", it within 24 hours of the day's range is relatively large, but also qualitative tests and more rough and sometimes shows positive nor instructions patient must be treated and should be identified more than once measurement. While Joel Yongmei believes that "the protein in the human body in the State up for too long, strenuous exercise, drink lots of milk after may produce, check to avoid physiological protein. "In addition, the urine specimen should not use preservatives; best use of urine test after centrifuging; urinary pH should be transferred to 7.0, and promptly check; in addition, quantitative, expressing 24h creatinine quantitative evaluation of urine specimen by quality.
Normal urinary protein as negative, weak positive or less 150mg/24h quantitatively (e.g. more than that is "proteinuria") "positive people have nothing to fear, especially males, may just be too strenuous exercise, such circumstances protein increase is not surprising, therefore, to further quantitative checks.
Sudden increase in urinary glucose?
Contraceptives in the role of "submarine"
Miss Chen in hospital for examination of urinary system, in urine check single accidents found himself a significant increase in urinary glucose, was characterized by positive! doctor after detailed further inspection revealed that the original Miss Chen's been nearly a year in pills, which led to increased urinary glucose.
Experts advise that certain medications such as corticosteroids or ACTH, contraceptives can cause urine.
So patients urine test results to the reference or exclude if there are more factors.
"Many patients always suspect you have diabetes or have their own urine has increased, but every day of the test results are not the same, so it is very disturbing.
"Home agent normal that some light patients often appears after the meal, and severe patients positive for every test almost all positive, that is the difference. Because different types of the metabolism of diabetes in urine test is not the same as in the show.
In addition, urine test positive are still not sufficient to make the diagnosis, but appears in urine glucose is considered confirmed diabetic feature, you will need to be further examined.
Simultaneous determination of urine and blood sugar, blood glucose than individual urine or check the more meaningful.
Urine ketone body check-positive?
In fact, is the hunger causes
Appears in urine ketone bodies may mean a lack of insulin in the body to metabolize glucose, fat for energy, more in the metabolism of type I diabetes mellitus patients.
But hope for teachers said that many patients in hunger therapy or not eat breakfast to the hospital for blood tests, at the made a urine ketone body check, "in this case, usually not tested positive of ketone bodies may arise, but this does not necessarily represent the patient ketone body poisoning. ”
Joel agent said, ketone bodies off the "poisoning" of the most common is starved of the test, the patient should be "fill in the belly" for the check.
In addition, if a child in acute onset may also appear in the urine, cold, tension after strenuous exercise, pregnancy, hyperthyroidism, etc. can cause increased urine ketone bodies.
Tube-type check-positive?
After strenuous exercise does not have to worry too much
In the urine check a sediment is urinary sediment hose, it only in renal tubular or collection tube formation, reflects the renal tubular shape and size of the inner radius.
"It's inspection results and a number of factors, is not absolute.
"Hope for ' that hose size correct judgment often vulnerable to the influence of several factors, such as transparent hose is found in healthy people, but is in the" morning concentrated urine, or after strenuous exercise State. "
Urine in transparent hose (and mildly particulate hose) sustainable appear decades; make transparent hose number of drugs have: amphotericin, pioneer MMC II, diuretics, and so on.
And another hose that particles
Hose, it reflects the nephron does stasis phenomena. It's judgment may be due to the following causes: strenuous exercise, high fever, pure carbohydrate diet, etc.
Check the yellow urine color?
And a lot of factors
Urine color is also an important general examination and public "like their judgement" of the project.
Huo-masters say that health status of urine should render yellow or pale brown, but the color of urine and a number of factors, particularly in relation with the urine of pigment. Experts believe that produced by the kidneys in urine pigment, excretion fixed basic urine color shades and parallel urine specific gravity. Large amounts of water, polyuria, urine color fade or colorless; conversely less concentrated urine, urine is deep yellow or strong tea.
Experts say that urine color do to figure out the problem of many diseases, such as urine color fade and the quantity is too small, may prompt renal adverse; dark brown or almost black is a possibility that high hemoglobinuria, hematuria.
Urine volume check changes big summer secretion?
Huo-masters say that a large number of physiological polyuria commonly found in drinking water or overdose has diuretic effects of food, and physiological oliguria often intake water too few or too many, and so sweating.
Hot summer weather, the children sweat more, than in winter convenient fewer, so parents need to worry too much. Parents for children when determining the amount of urine, it is first necessary to understand the child's diet features as well as drinking water, medication, and other physiological factors, excluded; second, it must be collected for several days of 24 hours all urine testing, objective and accurate.
Urine smell stink? may be long
Urine on long time automatically stink because urine in molecular decomposition, corruption will continue.
Huo-masters say that place too long, urine bacteria, can produce ammonia odor, the smell of urine should be fresh urine check in time. The public not because long reset urine "unpleasant" thinks they have the disease.
Why "pregnancy test is negative, positive"?
Huo-masters say, summer drink water, urine will become very clear, so random urine from urine concentration is not high, the reaction is not obvious, so be sure to use the morning urine.
"Because the urine in the bladder after a night of savings, we can guarantee the test require to achieve concentrations, which is the most secure and stable. "She said, a woman was measured in the morning, but do not worry, take direction during the day and continue to random, the results for" sometimes-negative sometimes positive "is not strange.
Urine examination cannot separate the "look"
Joel agent Division concluded that the formation of the urine is the body of each body metabolites with blood into the kidney after conversion, it can assist in all aspects of medical check-ups, direct examination of urinary system, etc system for metabolism, can also be observed various physical illness and treatment, such as diabetes, hepatitis, nephritis, so the effect is very big, but on the other hand, its inspection results and the human body is in motion, take the time, whether in the urine in disease, medication, and other factors are inextricably linked, so the people do not have a single conclusion to determine if they are suffering from some kind of trouble, it may be delayed or self leveling, preferably under the doctor's conduct "provisions of the Act", and the extraction, check the individual comprehensive feedback to the doctors, to arrive at a comprehensive, correct conclusion.
