Fee

$200.00 + GST There is no cost for NSW residents where an inborn error of metabolism is suspected or confirmed. All other patients will be billed and where the bill is to be paid by the patient we require a signed Patient Consent for Non-Rebateable Test Form. The NSW Biochemical Genetics Service charges referring laboratories for investigations on patients who do not have a suspected inherited disorder. Such cases might include plasma carnitine/acylcarnitines for patients on TPN, ketogenic diet or medication such as valproate.

Notes

Acyl carnitine values reported.

CSR: Spin, separate and freeze within 20 minutes of collection. Transport frozen.

Abnormal pattern of results consistent with an inborn error of metabolism would be notified to the ordering physician

Test code: ACARNP
