Table 3 Abnormal samples with high MCC rate detected by lower threshold value of aCGH

From: Array-based comparative genomic hybridization is more informative than conventional karyotyping and fluorescence in situ hybridization in the analysis of first-trimester spontaneous abortion

Case No. Routine threshold value
Log2ratio = 0.38
Lowered threshold value
Log2ratio = 0.26
MCC rate (%)
40 Normal +6 17.1
41 Normal +7 30.8
53 Normal +16 29.2
59 Normal +16 22.3
60 Normal +16 20.6
61 Normal +16 18.8
62 Normal +16 22.3
  1. MCC: maternal cell contamination.
