Question

Home blood glucose measurement devices measure the glucose level through an invasive method.

(a) True

(b) False

I had been asked this question in a job interview.

My question comes from Transmission of Analog Physiological Signals Over Telephone in chapter Biomedical Telemetry of Biomedical Instrumentation

Answer 1

The correct option is (a) True

To explain I would say: There is a small needle at the tip of the machine that pierces the skin to take a blood sample. Home blood glucose measurement devices measure the glucose level through invasive method. This blood is then undergoes electrochemical reactions and the glucose level is determined.
