Introduction
Phlebotomy is an essential aspect of healthcare that involves drawing blood for diagnostic purposes. Phlebotomy tubes, also known as blood collection tubes, play a critical role in the process of collecting blood samples for laboratory testing. These tubes are designed to preserve the integrity of the blood sample and ensure accurate Test Results.
Common Phlebotomy Tubes and Tests
Red-Top Tube
The red-top tube, also known as the serum tube, is one of the most commonly used phlebotomy tubes in the United States. This tube does not contain any additives or anticoagulants, making it suitable for tests that require serum samples. Some common tests conducted using a red-top tube include:
- Complete blood count (CBC)
- Basic metabolic panel (BMP)
- Lipid panel
Lavender-Top Tube
The lavender-top tube, also known as the EDTA tube, contains the Anticoagulant ethylenediaminetetraacetic acid (EDTA). This additive helps prevent blood clotting by binding to calcium ions. The lavender-top tube is commonly used for tests that require whole blood or plasma samples, such as:
- CBC with differential
- Blood typing
- Hemoglobin A1c
Green-Top Tube
The green-top tube, also known as the Heparin tube, contains the Anticoagulant Heparin, which inhibits thrombin formation. This tube is ideal for tests that require plasma samples and is commonly used for:
- Prothrombin Time (PT) and International Normalized Ratio (INR)
- Partial thromboplastin time (PTT)
- Fibrinogen level
Gray-Top Tube
The gray-top tube contains the Anticoagulant Sodium Fluoride and the preservative Potassium Oxalate. This tube is used for tests that require Blood Glucose levels to be preserved, such as:
- Glucose tolerance test
- Fasting blood sugar (FBS)
- Glucose monitoring
