An E4 displays on the meter, indicating not enough blood was drawn into the test strip for measurement or blood was applied after the test had started. You should discard the test strip and repeat the blood sugar test.
Be sure to clean the areas around slots and openings, while being careful not to get any moisture in them. You should also wipe down the entire meter surface, including the meter display.
Yes. In addition to the fingertip, you can collect blood samples from the palm, forearm or upper arm. Talk with your healthcare professional before deciding if alternate site testing is right for you.

Your Accu-Chek lancing device has a special plastic cap designed for testing on other areas of the body. Talk with your healthcare professional before deciding if alternate site testing is right for you.
Note: Do not use the special plastic cap when testing at the fingertip. Follow the steps for fingertip testing, with a few differences:
- Use the clear or gray cap.
- You may need a deeper setting. Try 3 for palm testing or 5-1/2 for forearm or upper arm testing. (These are suggested settings; yours may differ.)
- Press the opening of the clear or gray cap firmly against a fleshy area of the non-fingertip site. Press the lancing device up and down in a slow pumping motion to assist the flow of blood.
- Keep steady pressure on the area, then press and release the plunger. Do not be afraid to apply pressure to the area with the lancing device to assist the flow of blood. Continue to press the cap against the site for a few seconds to allow blood to come to the surface.
