Question 1 of 5

Which vacutainer tubes should be used when a requisition calls for blood to be drawn for an H&H and glucose test?

Correct Answer: D

Rationale: The correct answer is 'One green, one red.' An H&H test involves hemoglobin and hematocrit, which are components of a complete blood count and are typically drawn in a lavender tube. On the other hand, blood for glucose testing is collected in grey tubes.
Therefore, when drawing blood for both an H&H and glucose test, one green tube for glucose and one red tube for H&H should be used. The other choices are incorrect because light blue tubes are used for coagulation studies, lavender tubes are for complete blood counts, and green tubes are for chemistry tests like glucose, while grey tubes are specifically for glucose testing.
