Abstract:
<p>There are many direct and indirect methods of measuring the volumetric ratioof red blood cells relative to sample size and total blood, but the manual carcinogenic method remains the most stable and least expensive method despite the possibility of human error.The ratio percent of the packed red blood cell volume to the total volume of the blood sample is known as the packed cell volume (PCV). Our efforts were directed at finding a precise and economic method for PCV determination. There by, we designed a simple device consisting of a digital camera that is connected to a computer whi

Abstract:
ABSTRACT Packed cell volume (PCV) is commonly used to assess and monitor red blood cell count in animals, but the results can be altered if inappropriate ratios of anticoagulant/blood are used. The purpose of this study was to determine the effect of ideally filled, overfilled, and underfilled K3 ethylenediaminetetraacetic acid (EDTA) tubes with various volumes of healthy dog blood on centrifuged PCV. Six milliliters of blood was obtained from 94 blood donors each. Initial distribution was injected into two nonheparinized microhematocrit tubes. The remainder was instilled into 1.3 mL K3 EDTA s

Red blood cell (RBC) transfusions in 307 dogs were reviewed. A total of 658 units of RBCs, including 474 (72%) units of packed red blood cells (PRBCs) and 184 (28%) units of whole blood (WB), were administered. Reasons for transfusion included hemorrhage (n = 222), hemolysis (n = 43), and ineffective erythropoiesis (n = 42). The mean pretransfusion packed cell volume (PCV) of dogs with hemolysis (13%) was significantly lower (p less than 0.0001) than the mean pretransfusion PCVs of dogs with hemorrhage (21%) or ineffective erythropoiesis (18%).

Bovine blood samples with ethylene diamine tetra-acetate (EDTA) or oxalate as anticoagulant were stored at refrigeration temperature of 4°C. The packed cell volume (PCV) was determined daily. During storage, the PCV did not vary significantly. Complete haemolysis, suggested by failure of blood samples to separate into cellular and plasma fractions, started occuring in samples on days 28 and 17, and was observed to have occurred in all samples on days 41 and 24 in blood with EDTA and oxalate respectively.

Abstract:
Anaemia is a common morbidity in the NICU and often requires transfusion of packed red blood cells. Haematocrit equilibration following red cell transfusion occurs over time ultimately resulting in a stable packed cell volume (PCV). Knowledge of this equilibration process is pertinent in the accurate timing of posttransfusion (PT) PCV. We conducted a prospective study to determine an appropriate timing for PT PCV estimation on 47 stable anaemic babies at the Neonatal Unit of National Hospital, Abuja. Values of PCV were determined before transfusion and at 1, 6, 12, 24, and 48 hours posttransfu
