background/objective: neonatal septicemia is one of the major causes of mortality in newborns. the aim of this study is to evaluate the clinical manifestations and laboratory findings in positive blood culture in neonatal septicemia. methods: in this retrospective study, we allocated 100 records positive blood culture of neonates suffering from septicemia. a questionnaire was completed for each...

background: routine repeat testing of critical laboratory values is very common these days to increase their accuracy and to avoid reporting false or infeasible results. we figure that repeat testing of critical laboratory values has any benefits or not.   methods : we examined 2233 repeated critical laboratory values in 13 different hematology and chemistry tests including: hemoglobin, white b...

molecular diagnostic methods have played and continuing to have a critical role in clinical laboratories in recent years. therefore, standardization is an evolutionary process that needs to be upgrade with increasing scientific knowledge, improvement of the instruments and techniques. the aim of this study was to design a quality assurance program in order to have similar conditions for all med...

critical issue regarding to variation of findings based on different phenotypes led investigators to define whether they are distinct features or overlapping ones. therefore, we aimed to investigate the association between diverse phenotypes of pcos (poly cystic ovary syndrome) with clinical manifestations, anthropometric indices, and metabolic characteristics. this was a descriptive cross-sect...

abstract background and objective: proficiency testing schemes as a part of quality system in clinical and research laboratory centers provides the opportunity to evaluate the quality of test results. in this paper, we try to introduce the proficiency testing schemes as a useful method for achieving standardization and homogenization of test results in clinical and research laboratory centers. ...

ansi/ashrae 110-95 protocol is a widely acceptable method to assess the performance of laboratory hoods. in this test, sulfur hexafluoride (sf6) is applied as a tracer gas to quantitatively evaluate the performance of laboratory hoods. the environmentally hostile characteristics of sf6 as well as its cost are the major concerns. in the present study, the substitution of ethylene with sf6 in the...
