Which blood collection tube is associated with the AFP test?

The AFP test, or Alpha-Fetoprotein test, is typically performed to assess specific medical conditions, such as liver diseases and certain cancers, as well as monitoring fetal health during pregnancy. The blood collection tube associated with this test is the SST, or Serum Separator Tube, which contains a gel that helps separate serum from the cellular components of the blood upon centrifugation.

Using the SST is essential for the AFP test because it ensures that a clear serum sample is obtained, free from any cellular debris or clotted cells, allowing for accurate measurement of the AFP levels. The presence of a gel barrier in the SST also prevents contamination between the serum and the cellular components after centrifugation, further enhancing the reliability of the test results.
