Identification of Y Chromosome From Free Circulating DNA in Patients With Turner Syndrome

"In order to compare the performance of the ctDNA test with techniques used in routine diagnostics, we will compare the results obtained by the ctDNA test with those obtained by FISH.~compare the results obtained by the ctDNA test and FISH. This will enable us to identify a potential diagnostic gain. We will compare the percentage of patients for whom a positive test result result was obtained by the lncDNA test (Y chromosome detection) to the percentage of patients for whom a positive result was obtained by FISH."
