Blood glucose and severe trauma
In recent years there has been increasing interest in the significance of the transitory raised blood glucose (hyperglycemia) that very often occurs in individuals suffering critical illness and trauma. A number of studies have shown an association between hyperglycemia and poor outcome. Knowledge in this area is...

Clinical aspects of pleural fluid pH
Pleural effusion, defined as excess fluid in the pleural space, can complicate the course of a large and pathologically diverse range of pulmonary and non-pulmonary diseases. Laboratory analysis of pleural fluid provides much useful information for the clinician whose diagnostic challenge is the patient presenting...

Acute care testing at the point-of-care: now and in the future
The field of point-of-care testing (POCT) is entering a period of rapid expansion. This expansion is being driven by new evidence for clinical effectiveness of POCT, and new technologies that allow consolidation of testing onto smaller platforms.
Technological improvements will also lead to increased accuracy for...

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...

Reference intervals (2) - some practical considerations
This is the second of two articles focusing on the reference interval, the most widely used tool for interpretation of patient test results.
The first [1] was an introduction to the theoretical concepts that underpin the significance, construction and use of reference intervals. Here consideration is given to the...

An introduction to reference intervals (1) - some theoretical considerations
The population-based reference interval is the most
widely used tool for interpretation of individual patient
laboratory test results. The clinical value of those results
depend crucially on the reference intervals with which they are
compared, and all efforts directed at ensuring analytically
precise and accurate...

Limitation of pulse oximetry - a case report
Pulse oximetry provides a simple non-invasive method of monitoring
the oxygenation status of patients by indirectly measuring the
percentage of hemoglobin that is saturated with oxygen, i.e. %
oxygen saturation (SpO2). Pulse oximetry has important
limitations, including inaccurate readings in patients with
inherited...

Iatrogenic anemia - a downside of blood testing
All clinical procedures and treatments are associated with potential adverse effects of greater or lesser significance.
The undisputed value of blood testing for both diagnosis and monitoring of disease is tempered by the recognition that repeated blood sampling can result in blood loss of sufficient magnitude to...

Parameters that reflect the carbon dioxide content of blood
Updated with new information from a 2008 article! Health demands that despite quite significant variation in its rate of production, the amount of carbon dioxide in blood is maintained within well-defined narrow limits.
The homeostatic mechanisms that maintain the normal content of carbon dioxide in blood are...

Measurement of circulating glucose: The problem of inconsistent sample and methodology
There are few medical diagnoses that depend solely on the result of a single blood test, but diabetes mellitus, which is defined by concentration of circulating glucose, is one that does.
Quite apart from its long established role in diagnosis as well as life-long monitoring of diabetes, measurement of circulating...
