3. Refer to an MSDS (material safety data sheet). It is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner, and includes information such as physical data (melting point, boiling point, flash point, etc) toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill-handling procedures. This is a common problem even among highly skilled and experience phlebotomist. To eliminate this problem identify the best location for the venipuncture. To prevent missing a vein, do everything you can PRIOR to venipuncture to increase your chances of finding a vein suitable for the draw. Apply the tourniquet as tight as possible without causing pain to the patient. This will help make the veins stand out.
Palpate the vein and if needed, look for a "landmark" such as a mole, wrinkle, hair or freckle, to come back to. NEVER mark your patient with a pen or marker, Other reasons for failure may be that the tube has lost its vaccum due to a manufacturing defect, an expired tube, or a very fine crack in the rube itself. Always have a back-up tube.
Additionally, an improperly placed needle may be the source and slight repositioning may remedy the problem. The bevel of the needle may be resting against the wall of the vein (needing an only slight increase in your angle of insertion for correction), the needle may not be fully in the bein or the needle has passed through the vein. if the vein was missed completely, withdraw the needle
Try again a second time and final attempt. In no case should a phlebotomist ever attempt to draw blood from a patient a 3rd time. Always adhere to the 2-stick rule. Any tube that has been used for a blood draw but was unsuccessful in obtaining blood should ALWAYS be disposed in a sharps container
Additive: Silica, clot activator and, thixotropic Gel
Laboratory Responsible for specimen testing: chemistry
Several names are used to describe this tube; most commonly referred to as "SST" which stands for serum separation tube. it is also referred to as a "tiger-top-tube", "marble top", "red/gray speckled top", or gel.
Silica promotes rapid clot formation in the blood (15 minutes). This tube also contains thixotropic gel, a separator that creates a barrier between the serum and formed cellular elements when centrifuged. This barrier prevents contamination of the serum. After the sample is collected, it must be inverted 8 times to properly mix blood and additive. C-Reactive Protein test can be drawn in a serum separator tube if serum is required
Basic Metabolic Panel (BMP)
Complete/ Comprehensive Metabolic Panel/Profile (CMP)- Similar to BMP, this group of the test is a more comprehensive (complete) look at the patients' metabolism of chemicals in the body, kidney function, electrolytes and fluid balance. It also provides information about liver function and performance.
