A urine reagent strip or dipstick is a firm plastic strip to which pads saturated with chemicals are affixed. The chemicals in the pads indicate the presence of specific substances in the urine. The strips may also indicate the pH and specific gravity of the urine, depending on the type of strip that is used.
The urine dipstick test is the quickest way to test urine. Since it involves dipping a specially treated paper strip into a sample of your urine, The sample doesn't need to be sent to a laboratory for a urine dipstick test because this can be done easily with the results usually available within 1-2 minutes.
A urine dipstick test can look for the following:
pH or the level of acid in urine can be measured. Some types of kidney stones are more prone to develop in alkaline urine and others are more likely to from in acidic urine. Monitoring the urine pH may be helpful in preventing the formation of kidney stones.
Blood is not normally found in urine and may be an indication of infection. This can also be due to significant underlying disease such as cancer in the bladder or kidney and prostate gland in men. In women, it may only be contamination if you are on your period at the time of doing the sample.
Protein is normally found in the urine in tiny amounts but these tiny amounts aren't usually picked up on a urine dipstick test. Protein however, may be found in larger amounts if there is an infection or if you're pregnant and are developing pre-eclampsia. This can also be the first sign of kidney problem.
Glucose is a type of sugar that is never normally found in urine. If so, this may be a first sign of diabetes.
Ketones are chemicals made by the body when it’s breaking down fat for energy, this is what normally happens when we are starving and have used up all, or nearly all of our stored sugar. However, ketones are not usually found in urine, and are present when your diabetes is out of control and the levels of sugar in the blood are very high.
Bilirubin and Urobilinogen are chemicals produced by the liver and are not normally found in the urine. But if bilirubin is found in the urine it usually indicates a liver problem. While small amounts of urobilinogen is normal, large amounts may also suggest a liver problem or problem with the red blood cells being destroyed too quickly.
Leukocyte esterase and Nitrite are both indicators for the presence of infection. Leukocyte esterase test looks for a reaction that only happens if there are lots of white cells in the urine because white cells get into the urine when there is an infection. Nitrite is not normally found in the urine but will appear there if there are lots of germs or bacteria in the urine.
Specific Gravity or the comparison in density of urine to the density of water. This quick test can help determine how well your kidneys are diluting your urine. Urine that's too concentrated could mean that your kidneys aren't functioning properly or that you aren't drinking enough water.
Collect the sample. Get the client to pee or urinate straight into a sterile pot or container. The best sample is one which is called a midstream specimen of urine (MSU). This means that they start to pee, then pass the open container into the stream of urine, and then take it away again when they have caught enough urine. Ensure they tightly secure the lid on the pot then wash their hands.
Wait. Using a urine testing strip, make sure to immerse it into the sample urine reaching up to the last square. The strip has squares on it that changes its color in the presence of certain substances. After dipping, wait for about 60-120 seconds. You will start seeing the colors of the squares change.
Compare your colors. This will then be compared to a chart on the side of the urine testing strip package. Often the more intense the color change, the more of the substance there is in the urine. Urine can still be tested for some things if it isn't in a sterile container but the results might not be as accurate and the urine can't be tested for infection.
Liver Health Check and Kidney Health Check
The Liver and Kidneys carry out numerous functions such as excretion of waste, metabolism of many substances, hormonal regulation, and proper digestion, as well as proper coagulation.
Over time, conditions that damage the liver can lead to scarring (cirrhosis), which can lead to liver problems and can be life-threatening. But early treatment may give the liver time to heal.
Likewise, some kidney problems can be early signs of chronic kidney disease (CKD), the type of kidney damage that can get worse over time and lead to kidney problems or even kidney failure. Finding and treating these problems early can help prevent CKD from becoming kidney failure. Other kidney problems can lead to CKD if they are not treated. Hence, doing a simple regular examination of your urine may be key to earlier detection of liver and kidney problems.
