The evaluation of traditional and automatic Coulter method in estimation of haematological parameters in adult rats

Analytical Comparison between Microhematocrit and Automated Methods for Packed Cell Volume (PCV)

“…False low white blood cell WBC counts maybe observed because of agglutination in the presence of ethylene di amine tetra-acetic acid. Despite the sophistication of present day instruments, there is need to depend on manual techniques for primary calibration [6].The results of this study is in agreement with the study reported by Kakel, Sj, [15 ] in which higher PCV values were obtained from Coulter automated analyzer, eventhough there was no significant difference observed .…”

“…The automated hematology autoanalyzer with complete blood count (CBC) results has replaced the traditional manual or individual assay methods for hematological parameters [15]. Hematology auto analyzers provide quick and accurate results in most situations, however, false results related either to platelet of other parameters from complete blood count may be observed in several instances.…”

Determination of haematocrit using Mindray BC-2800Vet^® automated haematology analyser and microhaematocrit method: A comparative study

“…In these studies the value obtained for spun haematocrit was higher than the automated haematocrit value, this was contrary to the results in the present study where the spun haematocrit values obtained was significantly lower than the haematocrit obtained from automated haematology analyser. Kakel (2013) also reported a lower spun haematocrit than the automated value, although there was no significant difference observed. The differences obtained from previous studies mentioned above and in this study show no consistency in the results, hence the haematocrit obtained manually cannot be replaced by automated haematocrit.…”

Thermoacoustic assessment of hematocrit changes in human forearms*

“…[35] Most importantly, both methods require blood samples taken from subjects for the in vitro measurement, and cannot be used for in vivo determination of changes of Hct values. [36][37][38] Here, in this study, we demonstrate the ability of TAI to monitor changes in Hct both in vitro from the blood samples and in vivo from the blood vessels and muscle tissues in human forearms during vascular occlusion stimulation.…”
