Syringe, blood collection with

Urine Much attention is required in urine sampling due to the greater possibility of contamination and, hence, more skill is required than for a blood sample. The urine sample can be collected directly or from the urinary bladder. The samples can be collected with the help of an ETS system or syringe or a measuring cylinder made of plastic. The collected samples can be kept in polyethylene containers that can be closed with airtight lids. The samples should be analyzed immediately or preserved at low temperature, if analysis will take some time. 

Collection with Evacuated Blood Tube Evacuated blood tubes are usually considered to be less expensive and more convenient and easier to use than syringes. There are several types of evacuated tubes used for venipuncture collection. They vary by the type of additive... 

Platelet Adhesion. Venous blood from healthy human volunteers, who did not receive any agents which affect platelet function, was collected with a vacuum syringe containing 5 % citric acid. The blood was centrifuged at 800 rpm for 10 min at 25 C, and the platelet-rich plasma (PRP) was withdrawn with a polyethylene pipette and placed in clean vials at room temperature. A portion of PRP was diluted by adding PBS and centrifuged at 1800 rpm for 10 min to prepare platelet pellets. The residue of the blood was further centrifuged at 3,000 rpm for 10 min to obtain platelet-poor plasma (PPP). The platelet count was determined with Coulter Counter (Type 4) and adjusted to have 150,000 platelets in 1... 

Various body fluids, in addition to blood and urine, are available in forensic autopsy cases. These fluids include cerebrospinal fluid, vitreous humor, pericardial fluid, and bile. Samples can be collected with disposable syringes, with or without needles, and transferred to glass containers (5-10 ml) containing sodium fluoride at a final concentration of 1-2% as a preservative. As samples from living persons, the containers should be preserved at 4°C until analysis. Special care should be taken while testing for ethanol in postmortem samples since intestinal bacteria diffuse through the body after death via vascular system and induce putrefaction. In moderate to heavily... 

Our method for NMOR determination. The following procedure (carried out in a single day) was developed for blood, stomach contents, the homogenized whole mouse, and diet [(a standard semisynthetic diet prepared as in (9)]. After the rats were killed with C0 , we collected the blood (with a heparinized syringe from the heart) and the entire stomach contents. The whole mouse was frozen in liquid N2 and homogenized as in (2) ... 

Examination of cryoglobulins especially in patients with monoclonal IgM requires collection of at least 10 ml of blood into a prewarmed (to 37°C) tube or syringe, allowing the blood to clot at that temperature for 30-60 min prior to centrifugation to obtain serum. The serum sample should be stored at 4°C for up to 7 days. The presence of cryoglobulins in a formed precipitate should be confirmed by its solubility at 37°C, and further quantitated and characterized immunochem-ically (Kl). 

Collect blood by intiacaidiac puncture from a rabbit kept fasting for 12 h using a piasiic syringe with a No. i needie containing a suitable voivme of 3.8% m/V solution of sodium citrate R so that the final volume ratio of citrate solution to blood is 1.9. Separate the plasma by centrifugation at 1500-1800 g at 15-20% for 30 min. Use within 4 hr of collection. Store at D-O C.
