E-0 is an error code which means invalid hematocrit. There are 8 types of error on a true metrix meter. From e-0 to e-6 and e-9 are the errors on a true matrix. Different E means different types of error. It is not usually an internal issue. 

That still leaves some confusion, doesn’t it? To know what is invalid hematocrit, let’s dive into the article. 

What Does E-0 Mean on a True Metrix?

E-0 means invalid hematocrit. The message indicates the error in the red portion of the blood. You can face this issue for multiple reasons. 

While testing your diabetes on a true metrix it’s not usual to face this issue. But if you do, then you have to first identify the reason.

E-0 also can happen for the system fault. Here are some ways to find out the reason and how to resolve the issue. 

What Are the Reasons Behind This Error

If the true metrix shows the e-0 message, then there can be generally 3 specific reasons. Insufficient blood, stripe issue, and system issue. 

Here is a troubleshooting table to find out the specific issue.

Insufficient BloodCheck the strip and find out if the sensor part is wet by the blood. 
Stripe issue Change the strip and check again
Systems errorAfter applying those above two methods still does not resolve the issue? then it is a system issue. 

Do troubleshooting and find out the problem. Follow the instructions in the table. There can be a few reasons for showing this error. 

Reason 1: Insufficient Blood

The true metrix meter needs enough blood to measure glucose. If you do not put enough blood on the stripe then e-0 shows on the display.

There is no specific weight of how much blood does need. But the stripe sensor must cover the blood. Similar to the ozempic pen issues, which you inject to collect the blood. 


If you see e-0 on your true metrix then keep a new stripe. Then put enough blood on it. You can even take some extra blood. But remember, do not take less than the need. 

Again check, and this time your problem will be resolved. 

Reason 2: Stripe Issue

Stripe read the blood and sent the instruction to the true metrix meter. So, stripe plays a vital role in checking glucose. 

A bad stripe can show any type of error on your meter. 


Take a new stripe and check again. Sometimes the whole bundle can be bad. If the new one does the same even that is not enough to be sure. 

Buy a new bundle and try to check it again. If you have the option to return the bad ones then you can save your money. 

Reason 3: System error 

If the above two do not work then the problem is in the system. There can be different kinds of reasons behind system errors. 

It is the same as when the trulicity pen malfunctions. Your true metrix can be damaged for use for a long time. On the other hand, new ones can be bad from manufacturing.  


If you face a system fault issue then call for the assistant. If you have any guarantee or warranty then you can replace it or can get free service.

So check if you have those or not. For the system error, you must have to go to an expert.
