The tube used to test for glucose tolerance is typically a gray-top tube. This tube contains a preservative that helps prevent changes in glucose levels after the blood is drawn, ensuring accurate test results.
vanco trough is drawn in which color tube
The PTH (parathyroid hormone) is typically drawn into a lavender or EDTA tube for testing.
A thyroid test is typically drawn in a SST (serum separator tube), which is usually gold or red in color. The choice of tube color may vary depending on the laboratory or healthcare facility's standard practices.
The blood for IGF-1 is typically drawn in a plain red-top tube.
Red or lavendar
A gray tube is typically used for a glucose tolerance test. This tube contains sodium fluoride as an additive to preserve glucose levels in the blood sample.
TSH (Thyroid Stimulating Hormone) is typically drawn in a lavender/purple-top tube, which contains the anticoagulant EDTA. It is important to check with the specific laboratory or facility to confirm the correct tube color for this test.
red top
The tube top used for a glucose draw is typically gray. This tube contains sodium fluoride as a preservative and potassium oxalate as an anticoagulant to prevent the breakdown of glucose in the sample.
RBCs are typically drawn in a purple or lavender-top tube, which contains the anticoagulant EDTA. This type of tube is used for hematology studies and to prevent clotting of the blood sample.
ANA blood is typically drawn in a purple or lavender-colored tube, which contains the anticoagulant ethylenediaminetetraacetic acid (EDTA) to prevent clotting.
