FISH for Sex Determination


Using FISH techniques, our laboratory can provide sex determination results within 24 hours for blood and amniotic fluid specimens. Because this test is performed on interphase cells, culturing of the specimen is not required. Accurate and quick results are invaluable,if for example, you are treating an infant with ambiguous genitalia or you require confirmation for prenatal ultrasound findings.

Tissue samples require 3-4 weeks turn around time. Culturing of the cells provides better resolution for screening these types of specimens.

Methodology: Fluorescent in Situ Hybridization (FISH) Analysis

Purpose: Confirmation of Clinical Diagnosis

Test Requisition: Cytogenetics Requisition

Turn-around-time: 24-48 hours blood/amnio/buccal swab
