Blood glucose, also known as ‘blood sugar’, is what gives the body energy. It comes from the food we consume, as our body metabolizes the food. The blood circulates the sugar to the various cells in the body.

Excess sugar (hyperglycemia) or Low sugar (hypoglycemia) levels in the body can pose serious problems.

People with diabetes especially have to monitor their blood sugar levels, keeping it within a healthy range is a great idea, but not too low because that causes hypoglycemia. But regularly monitoring your blood glucose levels could be a lifesaver.

Diabetic patients, without enough insulin in the blood, cannot absorb blood glucose, so the body system looks for something else to use for energy. Thus, it starts converting fats into ketones which it uses for energy.

Having ketones gradually building up in the system of a diabetic person is not a good idea. It can lead to diabetic ketoacidosis and may be life-threatening. So, monitoring ketones in the body becomes essential too (in addition to blood glucose levels).

Precision Xtra glucose and ketone monitoring system is a product of Abbott Diabetes Care Inc. that cuts across various individual use. As one of the famous brands among monitoring systems, people with diabetes and others on a ketogenic diet have found this product to be fast, accurate, easy to use and of great help.

The versatility the Precision Xtra Blood Glucose & Ketone Monitoring System offers diabetics in testing not only blood glucose but blood ketone as well is meant to be one of it’s biggest benefits and why it is preferred to other glucometers in the market.

But there are many questions lie on real user experience about its practicality and accuracy.

In this Precision Xtra Blood Glucose & Ketone Monitoring System Review, we are going to answer the most common questions asked by users to provide you with a guide to help your decision-making process.

Before, looking into the review, let’s identify the instances when you might need to check your blood glucose and blood ketone levels.

When to Monitor Blood Sugar?

  • When you feel sick
  • When you experience hyperglycemia symptoms
    like frequent urination, sleepiness, excessive thirst, blurry vision.
  • When you have a job that requires blood glucose control
  • Also, when you start experiencing hypoglycemia symptoms like confusion, dizziness, twitching, losing muscle coordination, and feeling weak and tired.
  • When you need to monitor how changes in exercise, diet and medication affect your blood sugar levels.

When to Monitor Blood Ketone?

  • When you are on a keto diet
  • When you are insulin-dependent
  • When your blood glucose levels are above 250 mg/dl.
  • When you are sick and experiencing symptoms of diabetic ketoacidosis (DKA) like dehydration, confusion, hyperventilation, vomiting or rapid heartbeat (basically, they can be symptoms of undiagnosed or diagnosed diabetes. This can be a Medical Emergency – Call 911 or 000)

Tip: Precision Xtra does not measure blood A1c levels, which is an important measurement to key eye on. The good news is A1CNow+ System does that job.

What is the Precision Xtra Dual Glucometer?

When trying to monitor, understand and better manage diabetes, Precision Xtra Blood Glucose and Ketone Monitoring System is an all-new valuable tool for this purpose. Not only can you monitor blood glucose, but you can also monitor blood Ketone as an added feature to make things easier and further reduce the chances of ‘ignorance’ of a diabetes-related health emergency.

It is important to monitor your blood sugar and blood ketone according to your health professional’s recommendations.

Interpreting Your Precision Xtra Results

It is important to understand blood sugar levels and ketone levels to help in the management of diabetes. Interpreting your results could help avert diabetes complications and ketoacidosis.

The Precision Xtra glucose and ketone monitoring system also measures glucose average for 7 days, 14 days, and 30 days and stores the results in its 450-event memory.

Blood Glucose Levels Results

There are several opinions about the ideal set range for glucose levels, depending on your age and severity of diabetes. Diabetic individuals come with different needs and therapeutic responses that must be considered before a range is set. And, these things are to be discussed with a healthcare professional and decided by your diabetes care team.

Precision Xtra Meter measures blood glucose with US standard mg/dl (milligrams per deciliter). Other meters may use the UK or Australian standard mmol/L (millimoles per liter). In any case, mg/dl is approx. 18 times of mmol/l.

Here is a general guide about the blood glucose level you should target for.

You Circumstance Targeted Blood Glucose, mg/dL (mmol/L) Blood Ketone Check Actions
None-diabetic No diabetes 72 – 108 (4 – 6) No need to check None
Diabetic Before meal 63 – 99 (3.5 – 5.5) No need to check None
Diabetic After meal Less than 144 (<8) No need to check None
Diabetic Before meal 108 – 180 (6 – 10) Consider checking Contact your doctor, if it persists.
Diabetic Before meal 180 – 300 (10 – 16.7) Check blood ketone levels

*Check every 2 hours till it reduces to < 180mg/dl

*Contact your doctor

Diabetic Before meal Above 300 (≥16.7) Check blood ketone levels

Call 000 or 911, or

visit your local hospital or doctor.

  • A healthy individual without diabetes should measure between 72 – 108 mg/dl.
  • Diabetic individuals should measure between 63 – 99 mg/dl before a meal. And, less than 144 mg/dl after a meal.
  • If the range falls between 108 – 180 mg/dl before a meal, it is a little bit high. Contact your professional healthcare team if it persists.
  • Between 180 – 300 mg/dl before a meal is high, check after a couple of hours severally till it reduces to less than 180mg/dl.

If it doesn’t reduce but continues to increase, check your blood ketone levels and report to your healthcare professional.

  • Above 300 mg/dl is very high. You have to continue checking severally after every couple of hours. Also, check your blood ketone levels and take appropriate actions. Remember, this is likely to be a medical emergency!

Blood Ketone Levels Results

Following ketogenic low carb diet can be beneficial to general well being in most cases, even for diabetics. But when the body starts producing high levels of ketones as by-products, it is dangerous and can lead to diabetic ketoacidosis, especially for type 1 diabetes and insulin-dependent diabetes. It is therefore essential you measure ketone levels which will help in managing general healthcare.

Although in most cases, high ketones usually occur when there’s high sugar level in the body of about 230 mg/dl.

Depending on your blood glucose levels, here is a general guide about how you should go about the blood ketone level.

You Targeted Blood Ketone, mmol/L Targeted Blood Ketone, mg/dL Blood Ketone Actions
None-diabetic 0.5 –3 9 – 54 Normal None
Diabetic Less than 0.6 Less than 11 Normal None
Diabetic 0.6 – 1.5 11 – 27 Slightly high

*Check every 2 hours till it reduces to < 0.6

*Contact your doctor, if it persists.

Diabetic 1.5 – 3.0 27 – 54 High Contact your doctor
Diabetic Over 3.0 Over 54 Medical Emergency

Call 000 or 911, or

visit your local hospital or doctor.

  • A healthy ketone level will range between 0.5 –3 mmol/l and is considered nutritional ketosis for normal persons without diabetes.
  • For a diabetic, if the measurement falls below 0.6 mmol/l it is normal.
  • If it ranges between 0.6 – 1.5 mmol/l, ketone levels are slightly higher than normal and should be measured again after some time to see if it reduces.
  • Between 1.5 – 3 mmol/l indicates high ketone levels and risk of ketoacidosis. Healthcare professional should be contacted for counsel.
  • Now if blood ketones measure above 3 mmol/l, it is a dangerous level and requires immediate medical attention.

Customer reviews

Precision Xtra users on ketogenic diets commonly say that the Precision Xtra Meter has a precise accuracy with a simple design. Most people mentioned the kit from Amazon comes with enough strips and lancets to last about a month. Getting refill strips are also the cheapest on Amazon compared to most of other brands/units with ketone check capability.

One of our female clients, who started using Precision Xtra glucose and ketone monitoring system for the first time admitted it was overwhelming at first but soon found it quick and easy.

One user complained that his meter didn’t work but came up with an ‘E-7’ displayed on the monitor, which indicated that the device was faulty. However, he added that getting a replacement unit was a simple process.

A female user said the lancet device looked sturdy, cheap, fragile and challenging setting up. However, this was not the view of most of our clients and Precision Xtra users.


Over the years, Abbott’s Precision Xtra glucose and ketone monitoring system has made a name for itself and has striven to maintain quality and excellence in their products.

Despite a couple of minor limitations and newly sprung brand competition, it is still preferred by many. It has remained ones of the best recommendations for a glucometer with a ketone testing capability.
