tube color for Thyroid Stimulating Hormone test is the gold tube for chemistry testing.
A lavender or purple-top tube is typically used for thyroid function tests as it contains the anticoagulant EDTA. This tube is important for preserving the integrity of the sample for accurate testing.
A TSH blood draw typically goes into a lavender or purple-top tube containing an EDTA anticoagulant. This tube is used for testing thyroid-stimulating hormone (TSH) levels as part of thyroid function tests.
There are several tests done for thyroid function. They require different tubes.

A lavender or purple tube is typically used for TSH (Thyroid Stimulating Hormone) blood draw.
The colour tube commonly used for fasting blood tests is usually a plain red or gold-top tube. These tubes do not contain any additives that could affect the results of fasting blood tests.
The Corvac tube is a type of blood collection tube used to prevent clotting by containing an anticoagulant additive, such as EDTA or citrate. It is commonly used for collecting blood samples for various laboratory tests that require whole blood or plasma.
The red top tube typically contains a gel separator and is used for serum testing. It is commonly used for chemistry tests, blood bank studies, and some immunology tests. This tube is designed to allow the blood to clot and the serum to separate for testing.
Green (sodium/lithium heparin) or yellow/red a serum separator tube.
A lavender/purple top tube is typically used for renal function tests. This tube contains the anticoagulant EDTA, which helps preserve the blood sample for testing.
Laboratory tests that require blood collected in a heparin tube include activated partial thromboplastin time (aPTT), thrombin time, and some specialized tests for specific proteins involved in blood clotting. Heparin is an anticoagulant that prevents blood from clotting and is often used in tests that require plasma samples.
For A1c testing, you would typically collect blood in a lavender/purple-top tube, which contains the anticoagulant EDTA. This tube is used for tests that require whole blood or plasma.
