POCT data mining – an introduction
Point-of-care testing (POCT) results, like other forms
of laboratory data, hold potential hidden information that can be
utilized to improve patient care.
The technique of extracting
useful information from vast amounts of data is termed “data
mining”. Technological solutions are now available to meet the
challenges ...

POCT data mining – a practical approach
Simple data-mining algorithms can be applied to
point-of-care testing (POCT) data to document compliance of quality
control, operator training and to identify potential preanalytical
errors.
Data can be manipulated to automate manual review and other
laborious processes for identifying data trends, verifying...

Pneumatic tube transport of samples for blood gas analysis
The significance of good practice during the pretesting
phase of clinical laboratory investigation cannot be
overemphasized. The production of high-quality, accurate results,
which are clinically useful, depends as much on practice before the
patient’s sample reaches the laboratory as it does on the
analytical phase...

Understanding the principles behind blood gas sensor technology
Today’s blood gas sensors are the result of many
years of gradual improvements and optimizations. The operating
principles behind sensor technology have largely remained
unchanged, even though the size of analyzers and thus of
sensors has decreased remarkably.
However, miniaturization has
created a new challenge: to ...

Overcoming the limitations of barcode technology
The introduction of armband barcode scanning
capabilities to point-of-care glucose testing devices has been
shown to greatly reduce patient identification errors. Barcodes
may be scanned to identify operators, patient identification
and reagents. Barcode scanning, however, does not eliminate all
errors, and in some...

Quality assurance of the preanalytical phase - complying with ISO 15189:2003
A specimen for clinical laboratory testing must be properly collected from the correct patient at the correct time with proper patient preparation, and the right test must be performed for answering the right question.
Quality in the preanalytical phase of laboratory activity can be assured by implementing a quality...

Hematocrit - a review of different analytical methods
To assess anemia and reduced oxygen-carrying
capacity, a measurement of hematocrit and/or hemoglobin is
performed. Whether hemoglobin or hematocrit is preferred
depends on different needs and is often determined by
tradition.
Both hematocrit and hemoglobin are important
hematology parameters for diagnosing...

Diabetic ketoacidosis
Disturbance of the mechanisms which maintain normal
blood pH is a defining feature of diabetic ketoacidosis (DKA),
an acute and life-threatening complication of the chronic
metabolic disease, diabetes.
For this reason diagnosis and
monitoring of DKA invariably include measurement of arterial
blood gases. This...

Useful tips to avoid preanalytical errors in blood gas testing: neonatal total bilirubin
50-75 % of all newborns develop jaundice during their first week of life [1,2,3]. The decision behind which treatment is necessary and when it should be initiated is based upon a measurement of the concentration of total bilirubin (ctBil) in serum, plasma or whole blood.
It is therefore obvious that it is important...

Multiprofile blood gas method comparison studies
Numerous method comparison studies of blood gas analyzer methods have been published in the literature; unfortunately, several studies show flaws in one or several aspects of experimental design, execution, statistical analysis or interpretation of results. The most common flaw seems to be an inability to separate...
