Potassium EDTA (ethylenediaminetetraacetic acid)
Calcium is bound by the tube additive ethylenediaminetetraacetic acid (EDTA) during sample collection to prevent coagulation and preserve the integrity of the sample for testing.
A red tube is a zero additive tube, when testing for Lupus we need whole blood, so that means an anticoagulant is needed a. EDTA is in Lavender or Pink Hematology tubes and is used for ANA tests.
The additive in red-gray or red-black speckled collection tubes is typically a clot activator and gel separator. These additives help to separate the blood sample from the serum after centrifugation, allowing for easier testing of the serum without interference from clots or cells.
A basic metabolic panel (BMP) typically uses a green-top tube for blood collection. This tube contains a lithium heparin additive to prevent clotting and is suitable for most chemistry tests included in a BMP.
The color tube used for collecting plasma is typically green or lavender. The green tubes are often treated with heparin as an anticoagulant for plasma collection, while lavender tubes contain an EDTA additive.
Blood bank testing can be performed in a pink or lavender tube, which contains the anticoagulant EDTA. This additive helps preserve the structure of blood cells for accurate testing.
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.
A tiger top tube, also known as a serum separator tube, contains a gel barrier that separates the blood sample into serum and cells during centrifugation. This gel allows for easy collection and isolation of serum for various laboratory tests.
A urine microalbumin test typically requires a clean, sterile container or a plain, plastic tube for collection, rather than a specific colored tube. It's important to follow the specific instructions provided by the laboratory or healthcare provider for proper sample collection.
The tube for creatine kinase typically comes in a red or gold top tube. There is typically no additive required for creatine kinase testing as the serum or plasma is used directly for analysis.
The additive in a PST (plasma separator tube) tube is usually a gel or liquid that helps to separate plasma from whole blood after centrifugation. This allows for easier isolation of plasma for various laboratory tests.
