What Does "Urine Routine Test with Occult Blood" Mean?
Urine routine examination is a common item in various physical examinations. Finding a positive sign for occult blood in urine routine examination results can be particularly anxiety-provoking. Through urine routine examination, the body can understand whether there is diabetes or urinary system diseases, enabling timely detection of patients' disease symptoms and early treatment. Occult blood in urine routine examination suggests that there is a urinary tract infection, which may even induce urethral tumors.
1. What does a positive sign for occult blood in urine routine examination mean? During urine testing, sometimes pregnant women may find that some items on their test reports are marked with "+" signs, sometimes even more than one. Since the normal test results for many items are negative, they are usually indicated by (-), while positive results are indicated by "+" signs. The more "+" signs, the more exceeded the normal range.
a. There may be specimen contamination, especially when women leave urine on the urethra during menstruation, as menstrual specimens contaminated can cause occult blood in urine. Diseases such as urinary tract infection and urinary system stones can also lead to occult blood in urine.
b. Urethral tumors can also cause occult blood in urine. The presence of occult blood in urine for patients with glomerulonephritis may be due to kidney disease.
Notes for Urine Testing:
1. Diet does not affect the results of urine routine examination, and pregnant women can eat or drink before the test.
2. It is best to collect the middle segment of urine when collecting urine samples. Urine is divided into three segments: the first, middle, and last segments according to the order of excretion. Since the first and last segments of urine are easily contaminated, the middle segment is usually retained for urine routine and urine bacteriology tests.
3. A clean and dry container should be used to collect urine samples, or disposable urine cups and catheters provided by the hospital can be used.
4. Time for urine collection: Routine urine tests can be performed at any time. However, for patients with kidney diseases, to observe the results before and after treatment, the first urine sample in the morning is required for testing.
