Blood collection tubes are used in many tests, including hematology, drug levels, and basic chemistry tests. Blood collection vials are made from medical grade PET and are coated with microscopic silica particles to prevent breakage during handling and centrifuging.
Blood collection tubes are available with different coatings and additives. They also come in different sizes. Some tubes are made for specific types of tests, such as coagulation and hematology.
To prevent contamination, tubes are sealed. They contain microscopic silica particles and a recessed rubber stopper to avoid blood drops. They are also available with safe-lock closures.
After the blood has been drawn, the sample is mixed with a preservative. Then, the tube is inverted at least 8 to 10 times. Then, it is placed in a test tube rack. The specimen must be dated, and labeled with the date, patient name and initials.
If a test requires multiple samples, it is recommended that the patient removes multiple specimens from the arm and rotates the collection device. When the blood stops flowing, the specimens are removed from the arm.
The Hemogard(tm) Closure has a rubber stopper recessed in a plastic shield. This prevents blood splattering on opening the tube and protects health care workers.
The Gongdong patented non screw safety twist caps are a strong, durable construction. These caps are removable by gentle pull and are compatible with multi-types of automated analyzers.
