There are other error codes for different issues with True Metrix testing. I have compiled them all in one article for your convenience.
Let’s cut to the chase then!

Now, Prick the side of your finger. Squeeze your finger to bring out a droplet of blood. Turn on the True Metrix and put the blood droplet in the test strip.
Wait 4 seconds. The result will appear by then.
Remember not to squeeze your blood too hard. If you do so, you will have to take another test.

Solution
- Take the test again with a new test strip
- Be careful not to remove the strip before the meter displays the result.
- Calmly wait for the result to show up on display.

True Metrix Error Code E-9
You try to test your glucose level using True Metrix. You have done everything carefully. The error code E-9 shows up on display.
You take the test again. But the error code is persistent. What does E-9 mean?
Well, when True Matrix shows error code E-9 on display, it means a communication error.
Solution
Sadly, there’s nothing you can do to solve this. What you can do is call for assistance from the manufacturers. You may get your True Metrix fixed or they will send you a replacement.
Low Battery Sign
Do you see a small drained battery sign on the display? This means your battery is low or dead.
Solution
This is your reminder to change or recharge your batteries. One battery can hold till 50 tests. So be cautious when your reach closer to 50. Keep additional battery replacement in that case.
Hi or Lo Wrote on Display
This is a dangerous sign to be on display. If you see Hi or Lo on your display, the glucose is at a dangerous level.
To elaborate, if you see Hi on display, it means the blood glucose level is over 600mg/dL. This is a warning sign for hyperglycemia
And if you see Lo on display, this means that the blood sugar level is below 20mg/dL.
Both are very dangerous for a diabetic person. Extremely low levels of blood sugar can end in hypoglycemia.
Take the test again. If the sign shows again, immediately go to the doctor.
Precaution for True Metrix
Carefully avoid the mistakes for the True Matrix test. Because these mistakes can affect the result of True Metrix. So, be very cautious.
Control test
Make sure you perform a Control test before you use the True Metrix for the first time.
There are three levels of McKesson True Metrix control solutions. Be sure to test with all of them.
The testing method for the control solution is the same. Test it exactly how you test a blood sample. See whether the displayed glucose value and the glucose value on the container are the same. If they are, your True Metrix is functioning properly.
More precautions
Finally, there are some more precautions you should follow. This will ensure accurate results.
For accurate testing, keep these precautionary steps in mind:
- Do not reuse a test strip.
- Ensure there’s sufficient blood on the test strip.
- Do not wipe the meter with any liquid.
- Do not wipe the test strip with alcohol or water.
- Refrain from putting the second drop of blood to the test strip.
- Do not use the forearm blood for insulin calculation.
- Take only one test strip out at a time. Recap the vial fully afterward.
- Do not take multiple strips out of the vial at once.

FAQs
How do I reset the true Metrix?
Turn off the True Matrix meter. There’s a circular button on top of the meter, find it. Then push the circular button. And hold it down until the complete display appears. You will hear a sequence of beeps for 10 seconds. Turn off the circular button. Now your True Metrix meter is reset.
How do you know if your blood glucose meter is working properly?
You should test the control solution like you would test your blood. Compare the amount of glucose in the monitor to the amount printed on the solution container. The true metrix meter is working perfectly if both the values match.
Does squeezing the finger affect blood sugar reading?
It does. The researchers discovered that excessive pressure on the finger appeared to interfere with correct test results. 5 to 13% of study participants had significantly different blood sugar results due to that.
