How To Read Urine Temperature Strip?

Have you ever noticed that little strip of paper your doctor sometimes dips in your urine? Wondered how it works its magic? Well, fret no more, for I’m here to spill the beans on this nifty little invention. They call it a urine temperature strip and it can help detect if somethings cookin’ where it ain’t supposed to be!

We all know urinary tract infections are no fun. The temperatures these strips read can help your doctor figure out if one is brewing down below. It just takes a simple dip to get the reading – way better than sticking a thermometer somewhere it doesn’t wanna go!

I’ll walk you through everything you need to know about using one of these gizmos. We’ll cover what exactly they are when to bust them out, and how to get the sample and dunk it just right.

Then I’ll show you how to tell what the colors mean and if Fido is running a fever. By the end, you’ll be a pro at pee strip interpretation! Let’s jump in and I’ll spill all the insider secrets.

What is a Urine Temperature Strip?

A urine temperature strip is a simple but effective tool to measure temperature without needing extra medical equipment. It consists of a small strip of paper with indicators that change color in response to heat.

Urine temperature strips, also called urine test strips, are small strips of coated paper that are dipped directly into a urine sample. 

The strips contain heat-sensitive chemicals called thermochromes that will change color based on the temperature of the urine. 

This allows anyone to easily get a basic temperature reading without using traditional thermometers.

How Does it Work?

When the coated portion of the strip is immersed in urine for a brief second, the thermochromes react to the sample’s heat, darkening different areas to produce a color that corresponds to a temperature on a provided color chart. 

Within 10-15 seconds, you can simply match the strip to the chart to get a basic reading in degrees Fahrenheit or Celsius. It’s a fast, clean, and straightforward process.

When to Use a Urine Temperature Strip?

Urine temperature strips provide an easy way to get a general idea of your body’s temperature from the comfort of home. While not a clinical diagnosis, they can indicate whether a temperature check with a doctor may be needed.

Signs causing to check the temperature

If you are experiencing potential urinary tract infection (UTI) symptoms like burning with urination, frequent urges to go, or lower belly discomfort, checking your urine temperature is a good first step. 

Symptoms like back pain combined with abnormal urine could also signal a possible kidney infection. Checking for an elevated temperature may help determine if medical care is warranted.

Recommended Temperature Check Conditions

Conditions like UTIs, kidney infections, and unexplained fevers are often accompanied by higher than normal body temperatures. 

Getting a urine reading using a temporary strip can help decide if further evaluation by a healthcare provider should be pursued. Even common colds or seasonal influenza sometimes present with slight fevers.

Not a replacement for a clinical diagnosis

While reliable, these over-the-counter indicator strips should not replace a professional medical exam and diagnosis. 

However, they allow concerned individuals to keep tabs on possible temperature fluctuations from the convenience of their own bathroom as a preliminary screening method before seeking clinical advice or treatment when needed.

How To Read Urine Temperature Strip?

Getting an accurate temperature reading from a strip is simple when you follow a few basic steps.

Collection Methods

The best sample for a strip is midstream urine collected first thing in the morning before drinking or eating. 

This allows your body’s true temperature to be measured without possible contamination altering the results. Avoid samples sitting too long or collected into unclean containers.

How to Dip the Strip?

  • Remove the strip from its packaging being careful not to touch the reagent pads. 
  • Holding it by the plastic end, gently insert the pad end into the urine cup for 5 seconds. 
  • Swirl the strip to ensure full saturation of the pads, then remove and lay flat.

Reading Time

Leave the strip undisturbed on a non-reflective surface like your countertop or a napkin. Most will be ready within 10-15 minutes when the color-changing pads complete their reaction to the sample’s heat. Some may be slightly faster or slower, so follow the package instructions.


  • Do not remove the strip early or shake excess urine off.
  • Avoid touching the reactive color pads with your fingers which could impact results.
  • Properly discard the used strip per product disposal guidelines.

Reading Temperature Indications

We all know the deal – different colors mean different temperatures. But actually making sense of it takes a bit of practice. Lemme walk through how I interpret my sticks.

Color Ranges

The most important thing is having that color chart for reference. Basically, it shows a range for each color – like green might be 96-97°F and yellow is 98-99°F.

Normal and High Temperature

The usual healthy temp is around 97-99°F. But anything over 100.4°F is considered a fever. And little ones or elders can sometimes have low fevers at even lower temps.

If the stick shows a normal green or yellow but you feel yucky, pay attention. A reading higher up in the orange or red over 100°F when feeling sick could mean something’s brewin’ like an infection.

Constantly running high even when you feel fine might be worth a doctor’s check too, just to be safe.

It takes practice to get used to interpreting the colors. And remember, the stick can’t replace a doctor – if symptoms stick around, consult the pros. They’ll know best how to help.


We’ve covered a lot about using urine strips. It’s important to collect your sample correctly. We talked about how they work by revealing your body temp through different hues. It’s fascinating what they can tell us!

While useful for preliminary checks at home, pee strips can’t replace a doctor’s opinion. If symptoms persist or readings concern you, make an appointment. They have extra tools and knowledge to properly diagnose any issues.

Your health is so important, so don’t try to self-treat serious problems. These strips are good for keeping an eye on slight temperature changes but are not a substitute for professional medical care.
