Urinalysis strips are simple tools in the assessment of your health via a urine sample. These strips provide easy and fast insights about your kidneys, liver, or other body functions.
A urinalysis strip, after being dipped in your urine, is able to detect issues regarding infections, diabetes, and dehydration.
What is urinalysis?
Urinalysis is a test that takes a sample of your urine and examines it to know the general state of your health or potential illness. To identify anomalies, it examines your urine’s physical, chemical, and microscopic properties.
Urinalysis Strip
A urinalysis strip is a small, plastic stick with chemical pads on it. When these pads are dipped in your, their color changes. The color changes tell us about different substances in your urine, like sugar, proteins, or signs of infection.
The strips are used in hospitals, clinics, and even at home. They are an easy way to check if something might be wrong with your health. Many times, doctors use urinalysis strips to help diagnose a condition or to follow the course of a disease such as diabetes or kidney problems.
What Does a Urinalysis Strip Test For?
You can identify the following using a urinalysis strip:
This is a measure of whether your urine is acid or alkaline. The normal pH ranges from 4.5 to 8.0. A very low or high pH may indicate problems such as infections or kidney stones.
Presence of protein in your urine can mean kidney damage or other issues. A healthy kidney shouldn’t allow the passage of protein into the urine.
This helps us know if your urine contains sugar.
The presence of glucose in your urine can be due to diabetes or increased levels of blood sugar.
When your body uses fat as an energy source rather than sugar, ketones are produced.
A large presence of ketones in your urine can result from diabetes or starvation diets.
Blood in your urine might indicate an injury, infection, or kidney malfunction.
Leukocytes are a type of white blood cell, whereas nitrites are a type of by-product formed due to specific bacteria. Their presence might indicate urinary tract infections.
These are produced by your liver. Their presence can be indicative of liver issues, such as hepatitis or blockages of the bile ducts.
This checks the concentration of your urine. It can tell if you are dehydrated or if you take enough water.
