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.
and quick results are invaluable,if for example,
you are treating an infant with ambiguous genitalia or
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
