Sensitivity and specificity define the discriminative power of a diagnostic procedure, whereas predictive values relate to the predictive ability of a test to identify disease or its absence in individuals.  Predictive values are greatly influenced by the prevalence of the disease and should not be generalized beyond ...

Sepsis and septic shock lead to local and systemic activation of different response systems, including coagulation and fibrinolysis.  Despite numerous attempts the high mortality rate of these patients has remained stable over the last 20 years. In this overview the pathophysiological insights and possible...

Troponin values above the 99th percentile and increasing/falling values found by serial testing in addition to signs and symptoms of myocardial ischemia means AMI. Low troponin values, near or below the 99th percentile, can be used for prognosis. Highest hazard ratios were found when using the 90th percentile,...

Patients with heart failure (HF) experience significant morbidity and mortality and those admitted for acute decompensated HF are at particularly high risk for adverse events. Hospitalization represents the major component of the high cost associated with the management of patients with HF. Accordingly, early and...

The discriminative ability of a diagnostic procedure is called diagnostic accuracy, and a number of quantitative measures out of which sensitivity and specificity are mostly used in the biomedical literature can express it. Each diagnostic-accuracy measure relates to some specific aspects of a diagnostic procedure....

Timely and accurate diagnosis of sepsis is of great importance for the choice of treatment, level of monitoring and prognosis. For this biomarkers could be a significant aid, and thus the search for and application of sepsis biomarkers are of great importance.  Current evidence suggests that C-reactive protein and...

As point-of-care applications of lab testing demand more rapid and clinically integrated order entry and results-reporting processes, it becomes paramount for the laboratory to investigate entire clinical processes. Direct observation and process mapping of these clinical applications – end to end - are "lean" tools...

In an exclusive acutecaretesting.org interview, Dr Mario Plebani, Head of the Department of Laboratory Medicine at the University Hospital of Padova, Italy and international patient safety advocate, talks about how laboratory, clinicians and manufacturers can work together to reduce errors in testing and diagnosing...

Definite diagnosis of infection requires microbiological documentation; however, the identification of a specific etiology is frequently missing. In addition, bacterial cultures require at least 24-48 hours for a final result, which is too long for a decision to start antibiotics. Currently, the evaluation of the...

Chest pain is a frequent cause of hospitalization and comprises a significant proportion of the acute medical workload in the western world. This issue is compounded for those living in regional or remote communities due to limited access to pathology services and tertiary-referral institutions. Evidence suggests...
