The urine test, also known as a type 1 urine test or SAA (abnormal sediment elements) test, is a test typically requested by doctors to identify changes in the urinary and kidney system and should be done by testing the first urine of the day. because he’s more focused.
Urine collection for testing can be done at home and does not require fasting, but should be taken to the lab within 2 hours for testing. The type 1 urine test is one of the most requested tests by the doctor, as it reports on various aspects of the person’s health, as well as being quite simple and painless.
- In addition to SAA.
- There are other tests that evaluate urine.
- Such as the 24-hour urine test and the urine and uroculture test.
- That test urine to identify the presence of bacteria or fungi.
Your doctor requests the SAA test to evaluate your urinary and kidney systems, and is helpful in identifying urinary tract infections and kidney problems, such as kidney stones and kidney failure, for example. Thus, the EAS test allows to analyze certain physical, chemical aspects and the presence of abnormal elements in the urine, such as:
In addition, during the urine test, the presence and amount of leukocytes and epithelial cells in the urine is checked.
The sample for urine testing can be done in the lab or at home and the first urine in the morning should be collected, ignoring the first spray. Before taking the sample, it is important to clean the intimate area with soap and water to avoid contamination of the sample. Once the urine has been removed, the container must be transported to the laboratory within 2 hours for the test to be performed.
The 24-hour urine test identifies small changes in urine throughout the day and is done by accumulating all the urine removed during the day in a large container. This sample is then taken to the lab and tested to verify its composition and quantity, which helps identify changes such as kidney filtration problems, protein loss and even preeclampsia during pregnancy.

If the urine test reveals a positive nitrite, the presence of blood and many leukocytes, for example, this may be a sign of a urinary tract infection, but only the urine culture test confirms whether or not an infection is present. However, the type 1 urine test should not be used alone to diagnose a urinary problem. Understand what uroculture is and how it is done.
Normally, the amount of ascorbic acid in the urine (vitamin C) is also measured to see if there has been interference in the outcome of hemoglobin, glucose, nitrites, bilirubins and ketones, for example.
The increased amount of ascorbic acid in your urine may be due to the use of vitamin C medications or supplements or to excessive consumption of vitamin C-rich foods.
As a general rule, no special care is required before performing the urine test, but some doctors may ask you to avoid using vitamin C supplements, anthraquinonic laxatives or antibiotics, such as metronidazole, a few days before, as they may change the results.
It is also important to collect urine properly, as collecting the first spray or lack of hygiene can result in results that do not reflect the patient’s condition. In addition, women are not advised to have a urine test during their period, as the results may change.
There is a urine test that detects pregnancy through the amount of hCG hormone in your urine. This test is reliable, but when the test is performed too early or incorrectly, the result may go wrong. The ideal time to perform this test is 1 day after the day when menstruation should have appeared, and should be performed with the first urine of the morning, as this hormone is more concentrated in urine.
Even when the test is performed at the right time, the result may be false negative because the body may not have yet produced the hCG hormone in sufficient amounts to be detected. In this case, a new test must be performed after 1 week. This urine test is specific to detect pregnancy, so other urine tests such as the type 1 urine test or uroculture, for example, do not detect pregnancy.
