Using FISH techniques, our laboratory can provide results within 24-48 hours for blood, amniotic fluid, and buccal swab specimens. Receiving results quickly is invaluable, if for example, you are treating an infant with dysmorphic features and want to rule out Down syndrome, or you require confirmation for prenatal ultrasound findings for trisomy 13 or trisomy 18. The probes used in this assay have been approved by the FDA.
Methodology: Fluorescent in Situ Hybridization (FISH) Analysis
Purpose: Confirmation of Clinical Diagnosis/Prenatal Diagnosis
Down Syndrome ICD-10 Code Q90.9
Trisomy 13 ICD-10 Code Q91.7
Trisomy 18 ICD-10 Code Q91.3
Test Requisition: Cytogenetics Requisition
Turn-around-time: 24-48 hours for blood/amnio/buccal swab
Tissue samples require 3-4 weeks turn around time.
Culturing of the cells provides better resolution for
screening these types of specimens.
