Phlebotomy Tube Colors and Order of Draw Quiz

Blood cultures are specifically used to diagnose bacteremia by growing cultures from the blood sample in a liquid broth. It is important to follow instructions for sample collection and draw blood cultures first to prevent contamination.

This question is related to the specifics of a light blue blood collection tube, used for coagulation tests. The correct answers provide details about the additive, department, common tests, and inversion count associated with this type of tube.

In a medical laboratory setting, a Red Tube typically signifies a specific purpose related to the type of additive or department it is used in, the common tests conducted using samples from this tube, and the recommended inversion count while handling it.

The Red/Black (tiger top) TubeGold (YELLOW) tube is used for clot activator and gel separator during chemistry tests.

The correct answer is option 1 because the Mint Green Tube is specifically used with lithium heparin and gel for plasma separation, not related to a department, collection tests, or inversion count.

Green Tubes are primarily used for chemistry tests in the laboratory with common additives like lithium heparin, sodium heparin, and ammonium heparin. These tubes are typically processed quickly for stat tests, and the inversion count is important for proper mixing of the additives.

Lavender (purple) tubes usually contain EDTA as the additive to prevent blood clotting during testing. Heparin, citrate, and sodium fluoride are additives found in other types of blood collection tubes used for different purposes.

The Gray Tube is commonly used in chemistry departments and contains sodium fluoride as an additive. It is utilized for conducting various tests such as glucose, GTT, alcohol level, lactic acid, and BAC testing. The recommended inversion count for this tube is 8-10 times to ensure proper mixing of the additives with the blood sample.

The yellow tube is used for Sodium polyanethol sulfonate (SPS) which is an additive commonly used in microbiology along with Acid citrate dextrose (ACD). The department associated with the yellow tube is microbiology, where common tests such as blood cultures are conducted. The inversion count for the yellow tube is 8.

The correct answer lists the commonly used anticoagulants in blood collection, which are EDTA, citrate, heparin, and oxalate. These substances prevent blood clotting and are essential for preserving the integrity of blood samples for testing purposes.

Purple/Lavender tubes are used for hematology because they contain EDTA, which is an anticoagulant commonly used for blood tests. Other tube colors like red, green, and blue are used for different types of tests and do not contain EDTA.

Sodium citrate tubes with light-blue stoppers are used for coagulation tests to yield plasma. This type of tube is crucial in laboratories for certain blood tests.

Heparin acts as an anticoagulant by inhibiting thrombin formation, not promoting it. It does not promote platelet aggregation or inhibit fibrinolysis, so these options are incorrect.

The correct answer breaks down the phrase 'GO GRAY OX' by associating each word with its corresponding chemical element or compound. It is a mnemonic technique to remember the components of gray tubes.

The correct order of draw for blood collection tubes follows a specific sequence based on the type of additive in the tube and the tests to be performed. It is important to follow this order to ensure accurate results and prevent sample contamination.

The correct order of blood collecting tubes typically starts with Red, then Light Blue, followed by Tiger Top/Red Gray, then Green, Lavender, and finally Gray. Each tube is specifically designed for collecting different types of blood samples or tests.

The question refers to the technical use of 'green houses' as green tubes containing heparin for chemistry tests.
