In the US, I do not know of any meters that can be calibrated. However, they all come with control solution which can be used to test the accurancy of the strips. Check in your meter manual to find out how to do this. Comparision of meter results and blood results is only valid if the FASTING lab and meter sugars are compared simultaneously or within a minute of each other. Most authorities prefer that the results not be more than 10-15% different. Assuming that your 5.4 and 5.8 results were in moles, your results are considered in the acceptable range. The 4.7 and 6.4 readings cannnot be compared because they are not fasting.
