APPEARS WHEN
A Control Solution test is completed. However, if this
appears after a blood test, it means that your test result
was not accurate because the blood sample was too small
and the Meter read it as a Control Solution sample.
You are performing a Check Strip test. Turn the Check
Strip over and slide it back into the Test Strip Holder
with Side 2 up.
The Check Strip result falls into the acceptable range.
Your blood glucose result is above 33.3 mmol/L,
indicating severe hyperglycemia. Contact your
physician immediately.
