Before we dive into the scores, it's important to note that the greatest value of continuous glucose Monitors is tracking the trends of your glucose levels as opposed to point-in-time readings. Consequently, our scoring profiles are built out to reflect how your body reacted over the period of a day and during activities (food/ drink consumption, exercise, stressful events, etc.).
What is the Target Range?
Please note - the Target Range is customizable as chosen by your provider. The default range is 72 mg/dL - 110 mg/dL
The Target Range in Theia represents the optimal range for your glucose levels. Let's view the difference between the various segmentations we reviewed in the Glucose Overview article in comparison to the default Green Zone in Theia:
Subset | Non-Fasted Range |
Theia | 72-110 mg/dL |
Normal | 70-140 mg/dL |
Libre 3 App | 70-180 mg/dL |
Prediabetes | 140-199 mg/dL |
Diabetes | >200 mg/dL |
As you can see, the Theia range is more restrictive as we believe that this is the optimal glucose range for our bodies to be in. As you can see in the comparison, having a glucose reading outside of the Theia Target Range is not necessarily indicative of a health concern. Any medical advice from these readings should be provided by a health professional as Theia's scoring profiles are built to be aspirational as we monitor and improve our metabolic health.
Spikes
Glucose spikes refer to when your glucose levels rise beyond the top end of the glucose range (for the default scoring profile this would be any reading above 110 mg/dL). Spikes, although important, should be judged in the context of the cause of the rise in glucose. We'll discuss this in more detail below in the Activity Scores section of this article.
Dips
Glucose dips refer to when your glucose levels drop below the bottom end of the glucose range (for the default scoring profile this would be any reading below 72 mg/dL). Any reading below 72 mg/dL is defined as your body entering a hypoglycemic state; normalization of glucose reading back to within the Green Zone indicates that you are no longer in a hypoglycemic state as we can see in the patient's graph. It's also important to consider the context of how we arrived in this state. Below are some factors to consider
Is pressure being applied to the sensor (often owing to sleeping positions)? This can cause falsely low readings temporarily
Did this occur after a meal? What foods were consumed?
Did this occur while fasting? How long has it been since your last meal?
Hypoglycemia can be a serious medical problem and you should seek medical assistance if you're experiencing any symptoms such as dizziness, headache, or confusion.
Scores
Daily Scores
Please note - Daily Score difficulty can be customized as chosen by your provider.
This is Theia's daily score it gives all users.
Think of this score as a "check engine light' for the body. The way it works is it's a score from 0-100, with 100 being the best. This was done on purpose to utilize user-learned behavior since grade one where all of us learned that 100 is the highest mark we can get on a test.
There is also a ring around the daily metabolic score which changes color from red to yellow to green. The higher the metabolic score the closer and the darker the green becomes. The lower the score, the more red it becomes. The Daily Score algorithm considers a variety of factors such as the metrics below:
Average Glucose
Time in Range
Spikes & Normalization post occurrence
Stability
Variance
Daily scores are meant to track your body's performance over time and are meant to be aspirational. Each of our bodies are unique and will react differently to various inputs. One of the many benefits of the Continous Glucose Monitors is to be able to track what's not reacting well with your body and use those insights to create sustainable change.
Example of a low scoring daily metabolic score
Lots of glucose variability (constant ups and downs)
Less than half of time in range
Avg glucose well over 110mg/dl
Example of a moderately scoring daily metabolic score
Decent amount of glucose variability (although not as much as the example above)
Good amount of time in range
Avg glucose stayed within 85-110mg/dl
Example of a high scoring daily metabolic score
Low glucose variability (no dramatic ups and downs)
Very high time in range
Avg glucose stayed within 85-110mg/dl
Activity Scores
Please note - Activity Score difficulty can be customized as chosen by your provider.
Activities are defined as food/ consumption, exercise, stressful situations, etc. Activity scores provide an analysis of how your body reacted with any results above an 80 being considered a healthy score. As glucose levels rising during food consumption is an expected result activity scores are graded within a three-hour timeframe to judge how your body reacted to the activity. The Activity Score algorithm considers a variety of factors such as the metrics below:
Pre-activity reading (Preprandial)
Post-activity reading (Postprandial)
Time to Stabilize
Peak
Average
Example of an activity that scored poorly
You will notice that this gyro sandwich scored 35/100 and that the band is red. That is for the following reasons:
Glucose spiked over 140mg/dl
Not only did it spike over 140mg/dl however it went up to 181mg/dl (thus impacting the score more than a spike that say went to 145mg/dl)
Glucose spiked way over 30 mg/dl from one activity (impacting score more than had it spiked 32mg/dl from baseline)
For all of the reasons above, this activity had a low score. Taking a long time to stabilize back to baseline is another factor that can contribute to a low score, even if the spike isn't as high.
Example of an activity that scored moderately well
This bagel meal scored 74/100 with the band showing in yellow/orange. Here were the reasons for the score:
Glucose spiked over 140mg/dl
In this case spike to 152mg/dl vs. the 181mg/dl in the previous example (thus impacting the score less)
Glucose spiked over 30 mg/dl from baseline
Though it took a while to fully stabilize, time in range was high
β
Example of an activity that scored extremely well
This steak skewer meal scored a very high 95/100 and has a green band. Here is a breakdown of the score:
No notable spike in glucose
100% time in range
No hours to stabilize since there was no spike
