Dosage of chromosome specific cf DNA
Active
Description
The dosage of chromosome specific cell-free DNA (cf DNA) method has two basic steps. First, oligonucleotides that are known to be associated with chromosome-specific regions of interest are targeted and amplified using a sample of circulating cf DNA from maternal plasma, which is both maternal and fetal in origin. Second, the proportion of DNA contributed by each chromosome in the sample is compared to expected results in order to calculate a risk score for fetal chromosomal aneuploidies. For example, if the proportion of DNA from chromosome 21 is higher than expected, the result may indicate fetal Trisomy 21. Source: Regenstrief LOINC
