Percutaneous umbilical cord blood sampling (PUBS), also called cordocentesis, is a diagnostic genetic test that examines blood from the fetal umbilical cord to detect fetal abnormalities. PUBS provides a means of rapid chromosome analysis and is useful when information cannot be obtained through amniocentesis, CVS, or ultrasound (or if the results of these tests were inconclusive). This test carries a significant risk of complication and is typically reserved for pregnancies determined to be at high risk for genetic defect.

Famous quotes containing the words cord and/or blood:
“Ah! How neatly tied, in these people, is the umbilical cord of morality! Since they left their mothers they have never sinned, have they? They are apostles, they are the descendants of priests; one can only wonder from what source they draw their indignation, and above all how much they have pocketed to do this, and in any case what it has done for them.”
—Antonin Artaud (1896–1948)
“One memorable addition to the old mythology is due to this era,—the Christian fable. With what pains, and tears, and blood these centuries have woven this and added it to the mythology of mankind! The new Prometheus. With what miraculous consent, and patience, and persistency has this mythus been stamped on the memory of the race! It would seem as if it were in the progress of our mythology to dethrone Jehovah, and crown Christ in his stead.”
—Henry David Thoreau (1817–1862)
