Clinical Analyzers and Bacterial Contamination Issues

Bacteria can be a major problem for today’s busy biomedical laboratory, which often operates around the clock to provide vital support for clinicians. The quality of results depends on well-trained staff and well-maintained equipment, but also on the quality of reagents for the clinical analysis equipment and that includes the water too. Sub-standard results and delays caused by bacterial contamination cannot be permitted.

Potential bacterial threats include gram negative bacteria, such as Ralstonia pickettii, Sphingomonas paucimobilis, Caulobacter crescentus, and Pseudomonas aeruginosa. These can reproduce and contaminate analysis equipment, growing in the tubing, in on-board reservoir, the manifolds, reagent needles and the samples themselves. Levels of 105 – 106 bacteria can readily occur unless proper prevention is carried out.

To ensure a laboratory’s clinical analysis equipment only receives water of the correct purity, particularly with regard to bacterial content, it is important to ensure that the purification system contains all the correct elements. There must be an adequate and effective sanitisation procedure, efficient final filter selection and a general unit design that incorporates, a UV lamp, specific reservoir, recirculation loop, good storage tank design and virgin resins.

With attention to detail water purification can contribute to low rates of bacterial contamination and hence maximise analysis equipment uptime, providing water that complies with the most stringent regulations and levels below 10cfu/ml.
