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.

What is a venipuncture?
Venipuncture is a medical procedure of puncturing a vein with a needle, usually to obtain a blood sample for testing or to administer medications or intravenous fluids. It is commonly performed by healthcare professionals like phlebotomists, nurses, or doctors.
What color tube is a cbc?
A CBC (Complete Blood Count) is typically collected in a lavender-top tube that contains the anticoagulant EDTA (ethylenediaminetetraacetic acid). This additive helps preserve the blood sample for testing.
Why is the lavender tube filled first before the red tube when using syringe method?
Lavender tubes are typically filled first when using the syringe method because they contain an anticoagulant that helps prevent blood from clotting, ensuring a proper sample is obtained for testing. By drawing blood into the lavender tube first, the anticoagulant can mix with the blood efficiently. This order helps maintain sample integrity and accuracy of test results.
Can lipid be tested with lavender tube?
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.
What color tube is used for Ana with reflex?
A lavender top tube is typically used for collecting a sample for an ANA with reflex test.
List of different blood tests and the colour of bottle tops used in a vacutainer system when drawing blood for ANA?
To test for Antinuclear Antibodies (ANA), a blood sample is typically drawn using a lavender or purple top vacutainer, which contains EDTA as an anticoagulant. Other tests that may be performed alongside or in conjunction with ANA can use different colored tops, such as green for heparin or red for serum tests, but the lavender top is standard for ANA testing specifically. Always consult with a healthcare professional for the most accurate and relevant information.
How is a lipase test performed?
A lipase test is performed on a sample of the patient's blood, withdrawn from a vein into a vacuum tube. The procedure, which is called a venipuncture, takes about five minutes.
What happens in a BUN test?
The BUN test is performed on a sample of the patient's blood, withdrawn from a vein into a vacuum tube. The procedure, which is called a venipuncture, takes about five minutes.
What is a venipuncture?
Venipuncture is a medical procedure of puncturing a vein with a needle, usually to obtain a blood sample for testing or to administer medications or intravenous fluids. It is commonly performed by healthcare professionals like phlebotomists, nurses, or doctors.
What tube is used for herpes test?
A blood sample is typically used for testing herpes. This sample is usually collected through a venipuncture procedure, where blood is drawn from a vein in the arm using a vacutainer tube or a similar blood collection tube. The specific type of tube may vary depending on the laboratory's requirements.
Can you withdraw blood from a vacutainer with a syringe?
Yes, you can withdraw blood from a vacutainer using a syringe, but it requires a specific technique. First, you would need to use a transfer device or a specialized adapter to connect the syringe to the vacutainer. This allows for the safe and efficient transfer of blood without causing contamination or hemolysis. However, it’s essential to follow proper protocols and guidelines to ensure the integrity of the sample.
How is the Aspartate aminotransferase test done?
AST is determined by analysis of a blood sample, usually from taken from a venipuncture site at the bend of the elbow
How is a parathyroid hormone test taken?
A parathyroid hormone test is typically done by drawing a blood sample from a vein in your arm. The sample is then sent to a laboratory for analysis to measure the levels of parathyroid hormone in your blood. It is a simple and routine procedure that does not require any special preparation.
Can you draw from a picc usiing a vacutainer?
Yes, you can draw blood from a PICC (Peripherally Inserted Central Catheter) using a vacutainer, but it's important to follow proper protocols. Ensure that the PICC line is patent and sterile, and use the appropriate size and type of vacutainer for the sample needed. Always follow institutional guidelines and check for any specific orders related to blood draws from central lines. Additionally, it's crucial to maintain aseptic technique to prevent infection.
What color of vacutainer top do you use for vancomycin level?
For vancomycin level testing, a serum sample is typically collected using a red-top or gold-top vacutainer. The red-top contains no additives, while the gold-top contains a gel separator that allows for serum separation after centrifugation. It's important to ensure the sample is properly processed to obtain accurate results. Always check with your specific laboratory guidelines for any updates or variations.
What professional does hemoglobin tests?
A nurse or phlebotomist usually collects the sample by inserting a needle into a vein, or venipuncture, after cleaning the skin, which helps prevent infections.
Why should the alcohol applied be allowed to dry before performing a venipuncture?
Allowing the alcohol to dry before performing a venipuncture helps to ensure that the area is properly disinfected, reducing the risk of introducing bacteria into the bloodstream. Additionally, wet alcohol can interfere with some blood tests by diluting the blood sample.
