What does FISH FOR PRESENCE OR ABSENCE OF SRY IN CASE OF XY FEMALE OR XX MALE - (Outlab) measure?
This fluorescence in situ hybridization (FISH) test checks for the presence or absence of the SRY gene, a gene involved in typical male sex development. It may be used to help evaluate differences between chromosomal sex and physical sex characteristics, including in individuals described clinically as XY female or XX male. Results are interpreted together with chromosome studies, clinical findings, and other relevant tests.
