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 (DBS) 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, DBS sampling for HbA1c (diabetes), PSA (prostate), TSH (thyroid) and lipids (cholesterol and triglycerides) 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 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 the peer-reviewed journal BMC Clinical Pathology , show the accuracy and precision of dried blood spot testing for HbA1c.
Publications relating to PSA, TSH, total cholesterol and triglycerides are in preparation.
