OUR PATHOLOGY LAB
Our pathology test services are quality controlled.
The MyHealthTest laboratory conducts regular proficiency testing and participates in external quality control programs (where available) such as:
- The National RCPAQAP (Royal College of Pathologists of Australasia Quality Assurance Program)
- The International RIQAS (Randox International Quality Assessment Scheme)
Accuracy of dried blood spot testing
Dried blood spot testing has been demonstrated to provide accurate results for measuring a wide variety of compounds.
Dried blood spot testing was first introduced in 1963 by Guthrie and Susi and is now routinely used in heel-prick sampling and testing of newborn infants.
More recently, dried blood spot sampling for Diabetes (HbA1c) and Thyroid (TSH) testing have been developed and validated
The MyHealthTest DBS samples have been found to be comparable to using traditional whole blood venous samples.
The analysis of dried blood spot samples uses laboratory techniques that differ from traditional whole blood testing, and for some analytes the expected or reference range may differ from the range provided with the traditional serum or plasma samples. These DBS expected ranges are clearly provided with MyHealthTest results.
In 2015, researchers at the Australian National University’s John Curtin School of Medical Research conducted a comparative study of HbA1c (glycated haemoglobin) levels in dried blood spots versus venous (from a vein) whole blood. The results of this work have been published in peer-reviewed journal BMC Clinical Pathology. Improvements to the published method showing the accuracy and precision of the MyHealthTest HbA1c dried blood spot test can be viewed on our Diabetes clinical information page.
Publications relating to TSH are in preparation.
