Verification of methods and instruments
Analytical methods are often developed at one site and
transferred to other sites for routine use. Increasingly, the
method development is made by manufacturers of instruments and
reagents. Regulatory agencies have ruled that the
responsibility for the performance of IVDs in the laboratories
mainly should lie with...

D-dimer testing in the treatment and monitoring of septic patients
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...

D-dimer as a rule-out test for deep venous thrombosis: Gold standards and bias in negative predictive value
Recent studies of D-dimer as a “rule-out” test for deep venous thrombosis (DVT) frequently have used duplex ultrasound rather than venography as the gold standard.
Because duplex ultrasound has limited ability to image the calf veins, there is potential for ultrasound studies to classify patients with calf DVT as...

C-reactive protein and procalcitonin in the assessment of infection response to antibiotic therapy
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...

Troponin Testing and the Tyranny of Distance
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...

Point of care connectivity
With the use of a new Data Management System (DMS) software program [1], the majority of Point Of Care Testing (POCT) equipment throughout the Waikato District Health Board region has been connected to the Laboratory Information System (LIS) and the Hospital Information System (HIS).
Prior to the new DMS, viewing...

How to Avoid Preanalytical Testing Errors: A Virtual Roundtable Discussion
It is estimated that a majority of all laboratory medicine errors are errors that occur during the preanalytical phase of the laboratory testing cycle. Such errors have a significant impact on patient safety, staff workload, and hospital costs.
Correctly identifying patients and avoiding specimen-labeling errors are...

Point-of-care testing, now and in the near future
Introduction of point–of-care testing (POCT) in hospitals requires the use of principles of change management. Manufacturers can support this process.
E-learning programs adapted to the local situation with regular updates, a centralized accreditation and user-registration system and service level agreements are...

The Role of Physician Feedback in Improving Lab Utilization
Maintaining lasting progress in laboratory test utilization is difficult to do without a reminder tool for providers. Since implementation of a quarterly physician report card in 2003, we have seen sustained improvement in the ordering of wellness tests in an ambulatory care network in the United States for over four...
