Which tubes are associated with chemistry tests?

The association of specific tubes with chemistry tests primarily relates to the additives found in those tubes and how they interact with the blood sample. The green and gold/tiger top tubes are the correct choice because they contain additives specifically designed for chemistry tests.

Green tubes commonly have heparin as an anticoagulant, making them suitable for many chemistry tests, especially those requiring plasma. Gold and tiger top tubes typically have a gel separator and a clot activator, which allow for the collection of serum after centrifugation. These tubes are widely used for tests that analyze various biochemical components, such as electrolytes, enzymes, and hormones, because they allow for accurate measurement of these substances.

In contrast, the light blue and gray tubes are more often associated with coagulation studies and glucose testing, respectively, while red tubes are used for serology tests and may not contain additives for chemistry testing. Lavender tubes are primarily used for hematology tests. Thus, the specific composition of the green and gold/tiger top tubes aligns them closely with the requirements of chemistry tests.
