background the prognostic value of blood culture testing in the diagnosis of bacteremia is limited by contamination. objectives in this multicenter study, the aim was to evaluate the contamination rates of blood cultures as well as the parameters that affect the culture results. materials and methods sample collection practices and culture data obtained from 16 university/research hospitals wer...

by drawing blood through a heparin lock, patients can be protected from skin damages duo to repeated needle sticks. in addition, this procedure can assist to gain more precise results in laboratory test and to prevent further complications. probably, you have ever used a heparin lock in order to infusion of medicines but, it is possible that you never use of that for blood sampling. both two pr...

preparations of platelet concentrates (pcs) that are stored under blood bank conditions and used for transfusion purposes, appear to be enriched in platelet derived-microparticles (pmps) with high coagulant activity that may change platelet efficacy and safety issues. high shear stress could cause shedding of pmps from the platelet plasma membrane, platelet aggregation, and activation of the co...

The first documented transfusion of blood in humans occurred in 1667, but it was not until almost 300 years later that transfusion become a therapeutic practicality.1 Landsteiner’s landmark discovery in the early 1900s of blood groups and agglutinating antibodies was the key that unlocked this therapeutic pathway. The development of anticoagulants, blood preservatives, and sterile collection se...

A capillary blood collection technique which facilitates the estimation of routine haematological parameters, including platelet count and sedimentation rate, is described. The technique requires 0.5 ml of blood, allows closer reproducibility than pipette collection methods, is suitable for monitoring blood counts in patients receiving cytotoxic agents, and can be integrated with semi-and fully...
