Question 64

Gold and lavender top tubes are needed to perform an A1C, CBC, hepatic panel, and a comprehensive metabolic panel.

The phlebotomist will require gold and lavender top tubes for these specific tests. The gold tube is used for the comprehensive metabolic panel and hepatic panel, while the lavender tube is necessary for the CBC and A1C tests.

A) Yellow and blue

The yellow top tube is typically used for blood cultures and certain special tests, while the blue top tube is used for coagulation studies. Neither of these tubes is suitable for the A1C, CBC, hepatic panel, or comprehensive metabolic panel, making this option incorrect.

B) Gold and lavender

This option is correct as the gold top tube is used for serum tests which include the comprehensive metabolic panel and hepatic panel, while the lavender top tube is specifically used for hematology tests like the CBC and A1C. This combination fulfills the requirements for all the tests listed in the question.

C) Green and gray

Green top tubes are typically used for tests requiring plasma, such as certain chemistry tests, but they are not appropriate for the A1C or CBC. The gray top tube is usually for glucose testing and is not needed for the tests mentioned, thus this option is incorrect.

D) Red and black

The red top tube is used for serum tests, but it is not specific to the A1C or CBC tests. The black top tube is generally utilized for Westergren sedimentation rate tests. Therefore, this combination does not meet the requirements for the tests listed in the question.

Conclusion

The gold and lavender top tubes are the correct choice for performing an A1C, CBC, hepatic panel, and comprehensive metabolic panel due to their compatibility with the required tests. All other options fail to provide the necessary tubes for at least one of the required tests, confirming that B is the only suitable answer.
