By now, you have probably opted for a Keto diet and are looking for options to test your ketone levels. If you plan to do this, you can keep track of your ketones level by running a test for them and then adjust your diet accordingly for you to stay in ketosis so that you lose that stubborn fat.

Turns out, there are three ways of testing this; blood, urine, and breath test. For blood and breath tests, we have user-friendly testing meters available for purchase, whereas for Urine test, we need strips that are also easily available in the market.

Well, if you are following the Ketogenic diet, doing all that is required and eating only what is allowed, but you don’t see those numbers decreasing on the weighing machine? It is probably because you need to reach a certain level of ketosis, which can only be done if you test the level of ketones in your body.

Usually, a general rule of thumb when we want to decide between available options is to have an overview of what each option has to offer. Similarly, in this case, it’s wise to make our decision if we should go for a blood meter or a urine strip or a breath meter for testing our ketones by tapping in the features of each medium and comparing them together.

To begin with, here is a table for a brief comparison of each medium:

Factors to consider Blood Urine Breath
Precision (numeric reading) Quantitative No numeric calculation Quantitative
Price (200 strips) $200-300 $6-10 $250-950
Setup Quick Quickest Takes time to charge
Invasive/non-invasive Invasive Non-invasive Non-invasive
Power supply Long-lasting No power needed Power required at all times
Ease of use 3-4 steps 3 steps 2 steps
Alcohol friendly No affect No affect Affected results
Record data Saves data No data record Saves data
Test Reliability Extremely reliable Reliable during the initial phase of diet Least Reliable

No wonder this gives us an idea of what we should be going for. It is important we do a little check as to what suits us and what we are comfortable in doing. But before we finally decide on what to purchase, here is an insight on the pros and cons of all the three testers.

Testing Mode



Blood Meter

  • Accurate
  • Alcohol friendly
  • Numeric reading
  • Most prevalent
  • Quick results
  • Ease to use


  • Invasive
  • Inaccurately high reading if out of ketosis
  • Expensive
  • Difficult if you can’t use needles or see blood

Urine Strips

  • Widely used
  • Simplest
  • Cheap and inexpensive
  • Convenient
  • No exact measurement
  • Decreased accuracy as you become more keto-adapted
  • Inaccurate for nutritional ketosis
  • Hydration can influence readings

Breath meter

  • Non-invasive
  • Easy to use
  • Accurate
  • Device only, no strips required
  • Readings fluctuate due to environmental factors
  • Readings fluctuate due to eating habits
  • Sensor clogging issue
  • Varied results in different times of the day
  • Expensive
  • Not alcohol friendly


What’s the bottom Line?

You see, it’s pretty easy to choose, after going through the details of what each medium has in it for us. If you have just begun your Keto journey, you might like to start with Urine strips as they are inexpensive as well as handy.

In my own experience, the blood meters turn out to be the winner for measuring and monitoring your ketone level. They are accurate and thus recommended for Keto adapted bodies too. The breath meters however, are least recommended as the level of accuracy they provide is at the mercy of different external and environmental factors.
