Vacuum Blood Collection ESR Tube

Vacuum blood collection tubes, also known as vacuum tubes, are specialized tubes used for collecting blood samples for diagnostic testing. These tubes are designed to facilitate the collection, transportation, and processing of blood specimens in clinical laboratories.

Tube Design: Vacuum tubes are typically made of glass or plastic and come in various sizes, colors, and types, each intended for specific types of blood tests. The most common types include tubes for serum, plasma, whole blood, and specialized tests.

Vacuum System: The tubes contain a vacuum system, usually in the form of a rubber stopper or closure with a pre-attached needle or adapter. The vacuum inside the tube helps draw blood into the tube automatically when the needle punctures a vein.

Vacuum Tube Order of Draw: When multiple blood samples are required, there is a recommended order of draw to minimize cross-contamination between tubes and ensure accurate results. This order typically starts with tubes used for coagulation tests, followed by serum tubes, plasma tubes, and finally, tubes used for blood cell counts.

Additives and Anticoagulants: Vacuum tubes may contain various additives or anticoagulants depending on the type of test being performed. For example, tubes for serum tests usually do not contain any additives, while tubes for plasma tests may contain anticoagulants like heparin, EDTA, or citrate.

Collection Process: The healthcare professional performing the blood draw attaches a needle to the vacuum tube, punctures a vein, and allows the blood to flow into the tube. Once the required volume is collected, the tube is gently inverted to mix the blood with any additives or anticoagulants present.

Labeling and Transportation: After collection, the tube is labeled with patient information and other necessary details. It is then securely capped to prevent leakage and contamination. The tubes are typically transported to the laboratory for processing and analysis.

Vacuum blood collection tubes offer several advantages, including standardized sample volumes, reduced contamination risk, and improved safety for healthcare workers by minimizing exposure to blood. They have become a widely adopted method for blood collection in clinical settings due to their convenience and reliability.

ESR Tube is applicable to various automatic sedimentation analyzers. Due to the little volume and negative pressure inside the tube, it needs some time for blood collection. Do patiently wait until blood stops flowing into the tube. Then completely mix the anticoagulation and additive for 5-8 times, while inappropriate mixing will cause hemolysis, coagulation of blood blister and influence the test result．

◆ The sodium citrate solution is added to the blood collecting tube for anticoagulation, and the ratio of anticoagulant to blood is 1:4. ◆ For the determination of erythrocyte sedimentation rate.

ESR tube, also known as an Erythrocyte Sedimentation Rate tube, is a specialized blood collection tube used for measuring the erythrocyte sedimentation rate, which is a non-specific indicator of inflammation in the body.

Tube Design: ESR tubes are typically made of glass or plastic and have a larger diameter than regular blood collection tubes. The larger size allows for the accurate measurement of the erythrocyte sedimentation rate.

Anticoagulant: ESR tubes contain an anticoagulant, usually sodium citrate, to prevent blood clotting during the testing process. The most common concentration of sodium citrate used is 3.8%.

Blood-to-Anticoagulant Ratio: The recommended blood-to-anticoagulant ratio in ESR tubes is 4:1. This ratio ensures proper mixing of the blood sample with the anticoagulant and maintains the stability of the sample during the sedimentation process.

Sedimentation Process: To measure the erythrocyte sedimentation rate, blood is collected into the ESR tube, and the tube is gently inverted several times to mix the blood with the anticoagulant. The tube is then left undisturbed in an upright position for a specific period, usually one hour. During this time, red blood cells gradually settle to the bottom of the tube due to gravity.

ESR Measurement: After the sedimentation process is complete, the height of the clear plasma (the top layer) is measured and reported as the erythrocyte sedimentation rate. The rate is typically expressed in millimeters per hour (mm/hr).

Advantages

The vacuum blood collection tube adopts a fully automatic production line, and the quality is stable andreliable. According to diferent application area, blood collection tubes can be divided into serum bloodcollection tubes, plasma blood collection tubes, and whole blood collection tubes. lt is complete specification for the vacuum blood collection tube, and various special blood collection volumes and differentelevation tubes can be customized according to customer's special requirements.
