Final answer:
Blood glucose level test specimen should be protected from light.
Step-by-step explanation:
A PCT should recognize that the blood glucose level test specimen should be protected from light.
Exposure to light can affect the accuracy of blood glucose test results because sunlight and certain artificial light sources can break down glucose molecules, leading to inaccurate readings. Therefore, blood glucose test specimens are typically stored in amber-coloured tubes or protected from light to preserve the integrity of the sample.
For example, when performing a blood glucose test, a PCT would collect a blood sample from a patient and place it in a tube that prevents exposure to light. This ensures that the glucose molecules in the blood sample remain stable and do not break down, allowing for accurate measurement of the blood glucose level.
