Getting to know your glucose trends

A glucose reading gives you one piece of information. A curve shows how readings have changed over time, while a trend arrow adds information about the direction and rate of change. Understanding these differences can help you read your continuous glucose monitoring (CGM) display with more context. [1, 2]

At a glance

Reading and time

Check the glucose value together with the time it was measured.

Glucose curve

Look at the sequence of readings across the displayed time period.

Trend arrow

Read the arrow alongside the value, curve and your circumstances—not as a treatment instruction on its own. [1]

01 Start with the reading and its time

The Anytime 5 Series Instructions for Use, which include Anytime 5Pro, describe a monitoring screen showing the latest glucose value, its measurement time, a glucose curve and trend information. Checking the time is part of understanding which reading you are viewing. [1]

The sensor measures glucose in interstitial fluid, the fluid between the body's cells. This is a different measurement from a fingerstick blood glucose test. Sensor and blood glucose values can differ, particularly when glucose is changing quickly. [1]

02 Read the curve for context

A glucose curve brings a series of readings together. It can help you see how glucose has changed over a period of time, rather than looking at one isolated value. CGM also allows people to review patterns over hours or days. [1, 2]

When reviewing your history, note the time period you are looking at and what was happening around it. Meals, physical activity, medication, illness and stress can affect glucose readings. The Anytime app includes an event-recording function that lets you add details alongside your monitoring history. [1]

For a discussion with your healthcare professional, useful notes might include when you ate, when you were active and when you took prescribed medication. These notes provide context; a change on the curve alone does not establish its cause.

03 Understand what the arrow adds

The Anytime system calculates the rate of glucose change and displays this information as trend arrows. The arrows add direction and rate-of-change information to the reading. Consult the arrow guide in the Instructions for Use supplied with your device for the specific symbols and their meanings. [1]

An arrow is one part of the picture. The Instructions for Use state that treatment decisions require multiple data points and must not be based solely on a trend arrow or a single glucose value. Follow the plan agreed with your healthcare professional. [1]

04 Know when to check with a meter

If sensor readings or alerts do not match your symptoms or expectations, use a fingerstick blood glucose value from a blood glucose meter for treatment decisions, as directed in the Instructions for Use. Do not ignore symptoms that may be due to low or high glucose. [1]

The instructions describe additional situations requiring blood glucose testing, including missing glucose values and certain error or out-of-range displays. This article is not a complete checklist: read the full instructions supplied with your device. [1]

Bring the information together

For your next review with your healthcare professional, consider asking:

• Which patterns in my readings should we review together?

• What do the trend arrows on my device mean?

• When should I use my blood glucose meter?

• What should I do if a reading does not match how I feel?

Use the reading, time, curve and trend information together, alongside your symptoms and agreed care plan. Do not change medication based on this article.
