Our pathology lab
Our pathology testing service is accredited* and quality controlled.
The MyHealthTest laboratory, based in Canberra (ACT), has been accredited in the field of medical testing by the National Association for Testing Authorities, Australia (NATA) in conjunction with the Royal College of Pathologists of Australasia (RCPA).
To attain and maintain accreditation, our facility is regularly assessed for competence based on the relevant international standards.
This includes compliance with standards relating to:
- the qualifications, training and experience of staff
- equipment and its calibration and maintenance
- quality assurance procedures
- appropriate sampling practices
*Our scope of accreditation is detailed here, and includes our Diabetes (HbA1c) Test Service.
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), Prostate (PSA) 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, which have been published in peer-reviewed journal BMC Clinical Pathology, show the accuracy and precision of dried blood spot testing for HbA1c.
Publications relating to PSA and TSH are in preparation.
