Important notice: The anti-dsDNA FARR RIA assay will be temporarily unavailable
The anti-double stranded DNA (anti-dsDNA) Farr by radioimmunoassay (RIA) is temporarily unavailable because of an analyser maintenance issue. Replacement parts are required before the analyser can return to service. At this stage, repairs are anticipated to be completed within 1–2 weeks. However, there may be additional delays while the laboratory catches up on accumulated runs.
Interim testing and reporting
In the interim, anti-dsDNA antibody specimens will be tested using the Phadia ELIA assay. If an interim result is required for clinical decision-making, please telephone the QEII Immunology Laboratory on (08) 6383 4303.
Once the RIA analyser is operational, specimens tested during this interruption will be rerun using the Farr assay. Both the interim Phadia ELIA result and the subsequent Farr RIA result will be released to iCM.
Potential impact on other RIA assays
The analyser issue may also affect turnaround times for other radioimmunoassays, including acetylcholine receptor (AChR) antibodies and anti-MuSK antibodies. We apologise for any inconvenience and appreciate your understanding while repairs are undertaken.
