The kidneys discard all the waste materials generated after the metabolic and catabolic processes. Since there are several solid compounds, water is used by the kidney system for dissolution and proper excretion. Now, the urine produced by your body can tell many things about your health, especially that of the liver, pancreas, digestive gut, and the kidneys. You would notice that many doctors would advise you to go for a urine test so that you get to know about the health issue.
Since none of you is aware of the urine test and the related facts, here we have discussed the basic things about this medical procedure.
How is urine formed, and what does it contain?
Before understanding the A to Z of the urine test, you need to understand how urine is formed and what the function of the kidney here is. This way, you will be able to understand the basics of the examination, including the results.
Urine is formed in the nephrons- the building block of kidneys. There is a filter part known as the Malpighian corpuscle which is responsible for filtering of the blood entering the kidney. Here, water, along with other waste particles, blood cells, and some excess vitamins and minerals are absorbed. This is known as the filtrate, and it passes through the entire length of the nephron for the filtration. The blood cells and other kinds of essential compounds are reabsorbed into the blood. The urine is then collected in the ducts from all the nephrons and then stored in the bladder.
What are the causes that lead to urine examination?
Now you know the basic process of urine formation, and how the kidney takes part in it, it’s time to understand the causes which compel the doctor to suggest for a urine test.
- Pain in the lower back and the abdomen, especially in the region where the bladder and urethra are located.
- Abnormal glucose concentration has been reported indicating that you have diabetes.
- If you are taking too many medicines, the doctor will suggest for a test to examine whether the kidney is in perfect shape or not.
- In fever, doctors usually suggest having the urine tested to identify any infection.
- Unnatural yellowing of the urine’s colour usually needs to be examined using the urine test.
In what steps a urine test is performed?
For conducting a successful urine test, three different procedures are implemented. They are:
- Physical examination: first, the physical appearance of the urine is checked, which concerns the colour of the urine, thickness or density, paleness of the liquid, and so on.
- Chemical examination: a chemical examination is done by using a chromatography paper strip. For the urine examination, this strip has several stages indicating the presence of the basic substances present in the urine. When this strip is soaked in the treated urine, the absorption of the strip will separate the components and let you know about the chemical composition.
- Microscopic examination: For identifying the presence of physical compounds, microscopic examination is conducted. With this particular step, the pathologists can record the presence of blood cells, microorganisms, and other substances.
What can probable health issues be diagnosed from the urine examination result?
Once your doctor gets the results of the urine examination, he or she will be able to determine the following:
- The health of the kidney and liver
- Diabetes
- Bile concentration for jaundice inspection
- Trace of any infection in the kidney or other renal parts
Conclusion
Urine routine and culture examination is the most common diagnostic test conducted. But, only a handful of us knew about the test before this discussion. With this information, you are now aware of the urine test.
