The blood collection tube types for collection accessible in the laboratory are mentioned below. The descriptions for the red tube top, gold tube top, green tube top, lavender tube top, white tube top, blue top tube, and grey tube top may be found below.

With a few exceptions, vacutainer tubes are used to collect blood. The tubes carrying Anticoagulant must be filled to full to assure the accuracy of results.

An incorrect anticoagulant/blood ratio can be caused by an inadequately filled anticoagulated tube, which can alter the results.

Permit the vacutainer tube to fill before removing it from the collection mechanism.

Red Tube Top

The Red Tube Top has no anticoagulant and is suitable for tests that demand serum for analysis.

The red tube come in three sizes: 10ml, 5ml, and 3 ml, with no silicone barrier.

The only tube tops that can be utilized to obtain specimens for blood bank operations and all therapeutic medication levels are red tube tops.

Gold Tube Top       

The 6.0 mL gold top tube (Gold Top Hemoguard SSTT) is available.

It includes a clot booster as well as silicone, which when centrifuged forms a seal between the cells and serum. The gold tube can be used for serology, chemistry, and immunology testing.

Green Tube Top     

The anticoagulant is either lithium or sodium heparin coated on the interior wall of the green tube cap.

These are necessary for the gathering of some tests and can be utilized for a wide range of assays that need entire blood or plasma.

Amylase, lipase, troponin, AST, LIVP, CMP, and BHCG cannot be used with the green tube top. For chemistry testing, only green tubes containing lithium heparin as an anticoagulant are suitable.

Lavender tube Top

The anticoagulant EDTA (ethylenediamine tetra-acetate) is utilized in the lavender top tube for most haematological procedures. For molecular tests, these tubes are preferred. This lavender tube comes in a 3 ml capacity.

White Tube Top      

The white top tube type is utilized to collect HIV Viral Load specimens and contains EDTA (ethylenediamine tetra-acetate) K2.

The white tube, which comes in a 5 mL size, can also be used to collect specimens for Hepatitis C PCR testing (both qualitative and quantitative) and HIV-1 genotyping.

Blue Tube Top        

The anticoagulant in the Blue Top Tube is 3.2 percent Buffered Sodium Citrate.

There are two tube sizes available. 3.0 & 2.0ml tubes. Prothrombin duration and other coagulation investigations are performed with the blue tube.

Blue Tubes must be 90 percent full due to the needed blood-to-anticoagulant ratio for accuracy. Short samples will only be utilized with the authorization of the physician. Hemolysis that is clotted, moderate, or severe should be remembered.

Gray Tube Top

Sodium Fluoride Potassium Oxalate is found in the Gray Top Tube. It comes in a two-milliliter drawtube.

Lactic acid (which must be stored on ice and transferred to the lab quickly) and glucose tests are both done with it. Also as well as for several chemistry tests.
