For a thyroid panel, use a serum separator tube (SST) or a plain red-top tube to collect the blood sample. These tubes do not contain any additives and allow the serum to separate from the blood cells after centrifugation, which is required for thyroid testing.
Green (sodium/lithium heparin) or yellow/red a serum separator tube.
For iron panel tests, the test tube typically used is a lavender or purple-topped tube. These tubes contain an anticoagulant and are used for collecting whole blood samples for hematology tests including iron panels.
A gold-top tube with a gel separator is typically used to collect a Chem 8 (Comprehensive Metabolic Panel) test.
Gold tubes are not typically recommended for thyroid testing, as they contain a gel separator that could interfere with certain tests. It is best to use a plain red-top tube or a serum separator tube for thyroid function tests like measuring Thyroxine levels.
A color tube, specifically a gold or tiger top tube, is typically used for collecting blood for lipid panel tests. These tubes contain a gel separator that helps separate the serum from the blood cells after centrifugation, making it easier to obtain a clear serum sample for lipid analysis.
