In ecological risk assessment, a key necessity is to understand how contaminants known to have negative impact on laboratory mammals affect the population demography of mammals living in their natural environment. We examined the demography of six local populations of the short-tailed shrew (Blarina brevicauda) living in eastern deciduous forest palustrine habitat along the Housatonic River, Ma...

abstract objective: homeostasis model assessment of insulin resistance (homa-ir) is a simple and practical method for estimation of insulin resistance (ir), but a reliable reference interval (ri) of homa-ir is needed to deduce the threshold level to define ir. this ri has been controversial in different populations and even more divergent when considering factors like age, gender and body mass ...

Background & Objective: Appropriate use of laboratory testing is essential for achieving safe and effective care to patient. Insufficient kno...

The history and origins of proficiency testing of clinical laboratories are reviewed. Since the introduction of proficiency testing in the late 1940s, dramatic improvement in laboratory performance has been demonstrated. Nonetheless, the poor performance found two decades earlier was summoned to support the passage of the Clinical Laboratory Improvement Act of 1967 (CLIA '67).

In planning the internal organization of central laboratories, the future needs for clinical chemistry in hospitals must be considered. For the next decade the medical laboratory will primarily be concerned with the interpretation of laboratory data and with organizational problems, such as sample identification, specimen splitting and especially the timing of its service. The consequences for ...

Hemophilia A is a worldwide disorder of coagulation system. It is a male disorder, yet females with hemophilia are rarely seen in communities with high rate of consanguineous marriages. The abnormalities in factor VIII gene transfer as an X-linked pattern in the family, affects as many as one-third of patients who had no family history of abnormality and thus the occurrence of a sporadic mutati...

Historically, the trend toward automation in clinical pathology laboratories has largely bypassed the clinical microbiology laboratory. In this article, we review the historical impediments to automation in the microbiology laboratory and offer insight into the reasons why we believe that we are on the cusp of a dramatic change that will sweep a wave of automation into clinical microbiology lab...
