Lavender
The additive in a white top vacutainer tube is typically EDTA (ethylenediaminetetraacetic acid), which is a chelating agent used to bind and sequester calcium ions to inhibit coagulation by preventing blood clotting. It is commonly used for hematology testing.
Lavender-top tubes (containing EDTA as an anticoagulant) are generally used for hematology testing to prevent coagulation and preserve cell morphology.
When venipuncture is performed using a lavender vacutainer tube, the sample collected is typically used for hematology testing, such as complete blood count (CBC), erythrocyte sedimentation rate (ESR), and blood typing. The lavender top tube contains EDTA as an anticoagulant to preserve the blood sample for these types of tests.
The tube color used for hematology is typically lavender or purple. These tubes contain an anticoagulant called EDTA (ethylenediaminetetraacetic acid) to prevent blood clotting and maintain the integrity of the blood sample for hematological testing.
The color of the blood tube for HbA1c testing is typically lavender. Lavender-top tubes are used for collecting blood samples for hematology testing, including HbA1c.
For a blood chemistry test, commonly a lavender-top (EDTA) vacutainer tube is used. These tubes are used to collect whole blood samples for testing electrolytes, metabolites, and other chemical components in the blood.
A green-top vacutainer tube (or sometimes a pink-top tube) is typically used for collecting blood samples for lithium level testing. The green tube usually contains lithium heparin as an anticoagulant for plasma testing, while the pink tube may contain EDTA if plasma separation is not required. The specific tube color may vary depending on the lab's protocols, so it's best to confirm with the lab where the test will be performed.
A gold or red-top vacutainer tube is typically used for a basic metabolic panel (BMP) blood draw.
Red
The color top tube used to collect whole blood with an additive is typically a lavender or purple top tube. This type of tube is commonly used for collecting blood samples for hematology testing.
No, lipids cannot be tested with a lavender tube as lavender tubes typically contain an anticoagulant called EDTA and are used for hematology testing. Lipid testing usually requires a serum sample collected in a tube without additives, such as a red-top tube.
A red-topped Vacutainer tube is typically used to collect blood samples for dioxin testing. This tube contains no anticoagulant and allows for the blood to clot, making it suitable for serum or plasma separation prior to analysis.
