If the vacuum tube doesn’t fill properly and you’re sure you’ve entered the vein correctly, replace another tube. With injection technology, venipuncture is performed without a direct connection to the collection tube. If multiple tests are ordered that require frozen serum, a plastic transport tube should be prepared for each test. If multiple samples are required, remove the first collection tube from its holder as soon as blood flow is interrupted, turn the first tube upside down to prevent clotting, and gently insert the second tube into the holder.
Always use the correct vacuum tube for tests that require a specific anticoagulant (such as EDTA, heparin, sodium citrate, etc.) or preservative.
What are blood collection tubes made of?
Following LabCorp’s suggested collection, preparation, and transportation instructions support the best possible test results. To ensure accurate test results, all tubes containing an anticoagulant or preservative must be completely filled. The single-stage, closed system tube for blood collection, mononuclear cell separation, and transportation provides convenience, safety and reproducibility, which can contribute to increased laboratory productivity. This is your basic hematology tube (by which I mean identifying and counting blood cells, blood type, etc.)
What are blood collection tubes?
A blood collection tube is a sterile glass or plastic test tube with a colored rubber or plastic lid. The correct use of the collection principle when collecting multiple blood tubes is an essential aspect of ensuring high-quality laboratory test results. However, additional studies on the role of laboratory-related errors in the collection of laboratory tubes and their impact on the clinical environment may still be necessary to strengthen this information and, thus, their clinical relevance. Green tubes are often used to request statistical or immediate blood chemistry results in emergencies.
Laboratory tube collection is a procedure that is used when blood samples are taken from patients before they are tested in the laboratory.
