Madam, Identification of hepatitis C virus (HCV) as a major causative organism of non-A, non-B hepatitis (NANBH) in the late 1980’s and the development of a screening test has led to the introduction of routine tests for antibodies to HCV in 1991 in the U. K. and U.S.A. In Pakistan, apart from few voluntary blood bank services who have incorporated anti-HCV screening in 1994, majority of blood ...

Whereas plasma-derived clotting factor concentrates now have a very good safety record for not being infectious for lipid enveloped viruses, concern has arisen about the possibility that prion diseases might be transmitted by blood products. There is epidemiological evidence that classical sporadic Creutzfeld Jakob disease (CJD) is not transmitted by blood transfusion. There is now good evidenc...

The requirement for plasma products manufactured from both source and recovered plasma for the treatment of many medical conditions is projected to increase substantially in the course of the next 5 years [1]. Patient organizations representing many thousands of patients with rare disorders who are dependant on products manufactured from plasma formed a coalition of plasma usersPLUSin 2009. PLU...

We conducted a cross-sectional study to elucidate factors contributing to vasovagal reaction (VVR), the most frequent side effect following whole blood and apheresis donations. Complications recorded at the collection sites after voluntary donations by the Japanese Red Cross Tokyo Blood Center (JRC), in the 2006 and 2007 fiscal years, were analyzed by both univariate analysis and the multivaria...

BACKGROUND AND OBJECTIVES Plasma pools for the production of human plasma medicinal products are distinguished according to the collection method (recovered or apheresis plasma) and the donor remuneration status. National regulations and the physical status of the donor determine the donation frequency and plasma volume per session. Relevant protein contents of different types of pools have not...

Objective: This study aims to estimate and compare the time-course change in blood glucose levels by blood cells in serum, and plasma with or without preservatives, which may reflect the rate of glucose utilization by blood cells. Method: This laboratory-based cross-sectional study was carried out using a blood specimen of 28 participants among which 14 were diagnosed with diabetes and 14 were...

Over the past 20 years, there has been a major increase in the safety of the blood supply, as demonstrated by declining rates of posttransfusion infection and reductions in estimated residual risk for such infections. Reliable estimates of residual risk have been possible within the American Red Cross system because of the availability of a large amount of reliable and consistent data on donati...

BACKGROUND The aim of this study was to determine any relationships between return rates of first-time donors, number of donations in the first year and the donors' demographic characteristics. MATERIALS AND METHODS Data from 1,500 volunteer, first-time donors who donated blood at Shiraz Blood Transfusion Centre (Iran) were obtained from the donor database. The donors' demographic characteris...

introduction cold plasma is a self-sterilized, painless, and non-contact method in surgeries. these properties allow it to be applied to the living tissues and heat-sensitive parts. the aim of this study was to design a new cold plasma producer device and evaluate the effects of cold argon plasma on decreasing the coagulation time of blood drop in vitro and that of the injured liver blood in vi...
