The investigation of microdeletion and microduplication syndromes is now performed by microarray analysis. Microarray provides a superior investigation than FISH testing as it detect a wider range of genetic changes that may cause each syndrome. If an urgent investigation is required, FISH can be performed in 24-48 hours - please contact us to arrange testing.



Private and public patients: $144.85 (no bulk bill/Medicare rebate).
