Which blood bottle is used for uric acid level tests?

The correct answer is a Red top tube without gel, also known as a plain tube.

Uric acid is a chemical compound that is found in the blood and urine. It is produced when the body breaks down purines, which are compounds found in many foods, including meat, fish, and poultry. High levels of uric acid can lead to gout, a painful condition that causes inflammation in the joints.

A red top tube is used for uric acid level tests because it does not contain any anticoagulants, which can interfere with the test results. The blood is collected in the tube and then allowed to clot. The serum, which is the liquid part of the blood, is then separated from the clot and used to perform the test.
