GenSite prenatal genetic test using DNA probes data

APG (Houston, TX) presented results at the European Society of Human Genetics meeting, showing that probes for mRNA for fetal hemoglobin, and probes for chromosomes X, Y, 13, 18, and 21 could be combined into a one-step protocol that allows simultaneous hybridization with the hemoglobin and at least two chromosomes, with results available in an hour or less.

Blood samples from pregnant women were tested and compared to samples from five non-pregnant women and five men. None of the controls' cells hybridized with the probes for fetal hemoglobin mRNA. ...
