Question 4

Which quality control measure is mandatory before performing POCT on a patient sample?

Accepted Answer

Running both high and low control solutions on the POCT device

Answer

Running both high and low control solutions verifies that the POCT device is performing within acceptable ranges before patient testing.

Question 5

When performing a POCT glucose test using capillary blood, which finger site is preferred?
