Decoding “PC”: Patient Control Solution
The “PC” message on your OneTouch Verio Flex stands for Patient Control Solution. This message indicates that the meter is currently set to, or has recently been used with, the control solution mode. It’s a critical distinction because readings taken in PC mode are not representative of your actual blood glucose levels.
What is Control Solution?
Control solution is a liquid containing a known amount of glucose. It’s designed to verify that your meter and test strips are working correctly. By testing the control solution and comparing the result to the expected range printed on the test strip vial, you can ensure that your meter is providing accurate readings.
Why Use Control Solution?
Using control solution is essential for several reasons:
- Verifying Accuracy: It ensures that your meter and test strips are working correctly and providing accurate readings.
- New Meter or Test Strip Vial: It’s crucial to test the control solution when you first get a new meter or open a new vial of test strips.
- Suspect Readings: If you suspect that your meter is providing inaccurate readings, using control solution can help you troubleshoot the issue.
- Damaged or Exposed Test Strips: If your test strips have been exposed to extreme temperatures or humidity, control solution can help you determine if they are still viable.
- After Cleaning: After cleaning your meter, using control solution can verify that the cleaning process hasn’t affected its accuracy.
How to Use Control Solution with OneTouch Verio Flex
Using control solution with your OneTouch Verio Flex meter is a straightforward process:
- Insert a OneTouch Verio test strip into the meter.
- The meter will turn on automatically and display a flashing blood drop symbol.
- Apply a drop of OneTouch Verio control solution to the top edge of the test strip until the meter beeps and begins counting down. Make sure the control solution is at room temperature.
- The meter will display the control solution result.
- Compare the result to the control range printed on the test strip vial. If the result falls within the range, your meter and test strips are working correctly.
If the control solution result falls outside the specified range, there might be a problem with your meter, test strips, or technique. Repeat the control solution test. If the result is still outside the range, contact OneTouch customer support for assistance.
The Importance of Switching Back to Blood Glucose Mode
The most important thing to remember when you see “PC” on your OneTouch Verio Flex is that the meter is in control solution mode. It will not provide accurate blood glucose readings until you switch it back to blood glucose mode. Failure to do so can result in misinterpretation of the results, and potentially unsafe adjustments to medication or diet.
How to Exit Control Solution Mode
The method for exiting control solution mode varies depending on the specific OneTouch Verio Flex model. Generally, it involves navigating through the meter’s settings menu. Refer to your user manual for specific instructions on how to exit control solution mode on your particular meter. Look for a section related to control testing or settings.
Consequences of Not Switching Back
Failing to switch back to blood glucose mode after control testing can have significant consequences. If you take a blood glucose reading while the meter is in PC mode, the result will reflect the glucose level in the control solution, not your actual blood sugar. This can lead to:
- Incorrect Dosage: Making treatment decisions based on inaccurate readings can lead to inappropriate insulin dosages or other medication adjustments, resulting in either hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar).
- Delayed Treatment: Inaccurate readings can delay appropriate treatment for high or low blood sugar levels, potentially leading to serious health complications.
- False Sense of Security: Believing your blood sugar is within a safe range when it is not can lead to a false sense of security and a lack of necessary interventions.
- Emotional Distress: Repeatedly obtaining inaccurate readings can cause anxiety, frustration, and confusion, impacting your overall well-being and ability to manage your diabetes effectively.
Troubleshooting the “PC” Message
Sometimes, the “PC” message may appear even if you haven’t intentionally used the control solution. This could be due to a glitch in the meter’s software or an accidental activation of the control solution mode.
Steps to Take if “PC” Appears Unexpectedly
If the “PC” message appears unexpectedly, try the following troubleshooting steps:
- Check the Meter Settings: Carefully review the meter’s settings to ensure that it is not accidentally set to control solution mode. Navigate through the menu options and look for a setting related to control testing or solution.
- Restart the Meter: Turn the meter off and then back on. This can sometimes resolve minor software glitches.
- Remove and Reinsert the Battery: Removing and reinserting the battery can sometimes reset the meter and clear any erroneous settings.
- Consult the User Manual: Refer to your user manual for specific troubleshooting instructions related to the “PC” message. The manual may provide additional steps or insights into resolving the issue.
- Contact OneTouch Customer Support: If none of the above steps resolve the issue, contact OneTouch customer support for assistance. They can provide expert guidance and troubleshoot the problem further.

What does “PC” displayed on my OneTouch Verio Flex meter mean?
The “PC” displayed on your OneTouch Verio Flex meter indicates that the blood glucose reading was taken after a meal. “PC” stands for “Post-meal Check,” or “Postprandial Check.” This setting is crucial for accurately tracking how your blood sugar levels respond to food intake, which is a key aspect of diabetes management.
When you see “PC” on the meter, it signifies that the reading was tagged as being taken within a specific timeframe after eating. The exact timeframe is often customizable within the meter settings, typically ranging from one to two hours post-meal. This helps your healthcare provider understand your blood sugar patterns related to meal consumption and adjust your treatment plan accordingly.
How do I correctly use the PC setting on my OneTouch Verio Flex?
To use the PC setting correctly, you need to ensure that you tag your blood glucose reading as “Post-meal Check” on your meter after taking the measurement. Typically, you’ll find an option within the meter’s menu to select “PC” or “Before Meal” (sometimes labeled as “AC” for “Ante Cibum”). Selecting “PC” will timestamp the reading and store it with the appropriate tag.
Crucially, you should perform the test within the timeframe defined in your meter’s settings after you begin eating. This ensures the reading accurately reflects your post-meal glucose levels. Consistency is key; always tag your post-meal readings and record the time elapsed after eating to provide your healthcare provider with valuable information.
Why is it important to use the PC setting for post-meal glucose checks?
Using the PC setting is essential because post-meal blood glucose levels provide valuable insights into how your body processes carbohydrates and responds to the insulin (either your own or injected) in relation to food intake. This information helps identify if your meal plan or medication dosages need adjustment to better manage your blood sugar after eating.
Without correctly tagging your readings as “PC,” your healthcare provider will not be able to accurately assess your postprandial glucose control. Untagged readings or improperly tagged readings can lead to misinterpretations of your blood sugar patterns, potentially resulting in ineffective treatment adjustments. Accurate tagging facilitates better informed decisions.
Can I change the timeframe for the PC setting on my OneTouch Verio Flex?
Yes, the timeframe for the PC setting is usually customizable on the OneTouch Verio Flex meter. This allows you to tailor the setting to your specific needs and your healthcare provider’s recommendations. You can typically find this option within the meter’s settings menu, often under “General Settings” or a similar category.
Consult with your doctor or diabetes educator to determine the most appropriate timeframe for your post-meal checks. The standard timeframe is often one to two hours after starting your meal, but this may vary depending on your individual health condition, medications, and dietary habits. Setting the correct timeframe is essential for accurate tracking.
What happens if I forget to tag my reading as PC on my OneTouch Verio Flex?
If you forget to tag your reading as PC, the data will still be recorded on your meter, but it won’t be identified as a post-meal reading. This might make it harder to analyze your blood sugar patterns specifically related to food intake. While the reading itself isn’t lost, its context within your diabetes management is diminished.
If you realize you forgot to tag a reading, try to recall the time you took the measurement and correlate it with your meal schedule in your logbook or diabetes management app. While you can’t retroactively change the tag on the meter itself, you can make a note of it in your records. Consistency in tagging future readings is the best approach to prevent this issue.
Is the PC target range the same as the pre-meal target range?
No, the target range for post-meal (PC) blood glucose readings is generally different from the target range for pre-meal (AC) readings. This is because blood sugar levels naturally rise after eating as your body digests food and absorbs glucose into the bloodstream.
Your healthcare provider will provide you with specific target ranges for both pre-meal and post-meal blood glucose levels, tailored to your individual needs and health condition. It’s crucial to understand these different target ranges to properly interpret your readings and make informed decisions about your diabetes management. Always consult with your doctor for personalized guidance.
Where can I find more information about the PC setting on my OneTouch Verio Flex?
The primary resource for detailed information about the PC setting and all other features of your OneTouch Verio Flex meter is the user manual that came with the device. The manual provides step-by-step instructions on how to use the meter, including how to set and utilize the PC function effectively.
