That means the test says something's wrong when it's not. False negative results can occur when an insufficient amount of fetal cfDNA is present in the sample, resulting in masking on the fetal phenotype by the maternal cfDNA. However, reliability of positive screening results was far lower for microdeletions, with the positive predictive value ranging from about 2% to 30%, depending on the condition.
