When veterinarians are purchasing supplies for blood collection, they must consider several important factors. These include the specific size and type of animal, the frequency at which blood will be collected, and the volume of testing required. For specialized applications, customization options for blood collection tubes can be valuable. Options may include selecting the color of the rubber tops or specific configurations for chemical additives, tailored to unique veterinary requirements.
Air-Tite is recognized for its extensive variety of veterinary blood collection tubes, which encompasses not only their high-quality Air-Tite branded vacutainers but also selections from reputable brands like BD. You have the flexibility to choose from a range of trusted products or collaborate with Air-Tite to design customized tubes with the guidance of our Animal Health Manager. With so many alternatives available, understanding what to prioritize during your selection process is essential.
Determining the appropriate size of the blood collection tube is paramount for veterinary practices. Vacutainer volumes offered by BD and Air-Tite generally range from 3 to 10 milliliters.
Larger animals, such as cows, horses, or pigs, typically require larger collection tubes than smaller pets like cats and dogs. Additionally, specific tests might necessitate precise volumes of blood. Collecting a larger volume at once can reduce the need for multiple blood draws and allow for various tests, including backup samples for verification.
However, opting for larger tubes indiscriminately may lead to issues, as excess space can negatively affect the sample's integrity. It is advisable to select a tube size that adequately accommodates the required blood sample along with any necessary additives.
Many blood tests necessitate that the collected blood sample is combined with specific additives. Certain blood collection tubes come preloaded with these additives, which need to be carefully considered during supply preparation.
For instance, some chemical preservatives are crucial for maintaining the blood sample's stability. To separate blood cells from serum, a gel additive that has an intermediate density can facilitate this process effectively.
Air-Tite produces yellow top tubes equipped with a gel barrier located at the bottom. Upon centrifugation, this gel barrier shifts and forms a stable partition between the red blood cells and serum, remaining intact for up to 48 hours.
Additionally, many blood collection tubes incorporate additives to either spur or impede clotting. These activators and anticoagulants create optimal conditions necessary for accurate testing outcomes.
The various colored rubber tops on these vacutainers typically indicate the type of additive contained within each tube. Common configurations include:
At Air-Tite, you can select any color combination you require. Our Animal Health Manager is available to assist you in customizing blood collection tubes tailored to your practice's needs.
When utilizing EDTA, it is crucial to select a collection tube of the correct size and ensure that the tube is filled to over half its capacity. Underfilling can induce red blood cell shrinkage, resulting in altered cell volume and hemoglobin concentration readings.
Sample tubes should never be shaken; instead, gently invert or roll the tube in your hands to mix the EDTA with the blood sample thoroughly. Blood samples containing EDTA should be kept refrigerated and transported alongside a cold pack. Care must be taken to prevent direct contact between the sample and the cold pack (for instance, by wrapping the sample with paper towels) as freezing may lead to hemolysis.
Some laboratories recommend obtaining peripheral blood smears if there is a delay anticipated between collection and analysis. Always ensure samples are properly marked and labeled with the animal's identification, date, and any additional details.
EDTA is widely deemed the preferred anticoagulant for mammals and numerous other species. However, certain birds, turtles, and reptiles may experience hemolysis when exposed to EDTA, which can compromise sample quality. In such cases, citrate anticoagulant should be administered into the syringe prior to blood collection. It is essential to maintain a precise citrate-to-blood ratio to account for dilution when evaluating the sample.
For tailored recommendations on tubes and additives suitable for your specific needs, consult with an expert at Air-Tite.
Veterinarians often seek custom blood collection tubes for various reasons, with common modifications including rubber top color, tube size, and additive composition. Options are available for both glass and plastic materials, along with possibilities for private labeling or brand-specific vacutainers.
After determining the desired vacutainer specifications and quantities, Air-Tite liaises with suppliers to finalize pricing and lead times. Our customers particularly appreciate the smooth transaction experience facilitated by efficient suppliers.
Products from Air-Tite are crafted to fulfill the same functional requirements as BD vacutainers. We adhere to industry-standard colors that denote additive types and sizes. Being a smaller enterprise allows us to effectively manage our inventory to satisfy customer demands and mitigate discontinuation concerns. Whether you choose a known brand or explore Air-Tite's proprietary products, rest assured that we have your needs covered.
Once the appropriate tube size and additives are determined, the next crucial step involves selecting the right blood collecting needle and any supplementary accessories. Whether working within a veterinary clinic, laboratory, or agricultural context, the needle size is equally significant as the volume of the collection tube.
Vacuum collection tubes utilize multiple draw needles. Available options include two primary sterile needle types: Single-Use and Multi-Type. A Single-Use needle is a double-ended stainless steel needle intended for use alongside blood collecting needle holders and tubes, whereas a Multi-Type needle features a retractable sheath that covers the portion penetrating the blood tube, allowing for multiple samples to be drawn through a single puncture.
For animal health needs, we have identified common demand for 18g to 20g needles. Air-Tite Products provides a variety of blood collection needles ranging from 18g to 22g, with lengths from 1" to 1 ½" to meet your specifications.
