Pharmacogenetics (PGx), an important part of precision medicine, is the study of how genetic variability influences drug treatment outcomes. Recommended by Guidelines, many medications currently prescribed have pharmacogenetic data to support appropriate dosing or selection. Like all diagnostic tests, pharmacotherapeutic genotyping is one of multiple pieces of information that clinicians should consider when making their therapeutic choice for each patient.
Clinical Labs offers a comprehensive range of pharmacogenetic testing in order to provide Clinicians and healthcare providers with important information to help decide on the most appropriate treatment for each individual, particularly in areas such as mental health, pain management, cardiology and oncology.
"The field of pharmacogenetics involves using a patient’s genetic makeup in combination with other clinical information to create a personalised medication regimen with greater efficacy and safety for the individual patient."
Pharmacogenetic (PGx) test list at Australian Clinical Labs
Our comprehensive pharmacogenetic tests can detect polymorphisms in genes coding for drug metabolising enzymes that predispose individuals to metabolising drugs inadequately.
Gene panels offered:
• Cytochrome P450 Comprehensive Gene Panel including*:
CYP2D6, CYP2C9, CYP2C19, CYP3A4, CYP3A5, CYP1A2, SLCO1B1 and VKORC1
Single gene tests:
• TPMT (Medicare rebate)
*Please note that the panel Cytochrome P450 Genes can be ordered separately or together (CYP2D6, CYP2C9, CYP2C19, CYP3A4, CYP3A5, CYP1A2, SLCO1B1 and VKORC1).
