Blood test may help explain pregnancy loss

HVIDOVRE, Denmark: A blood test taken after a miscarriage suffered as early as week five of pregnancy can help explain why it occurred and in some cases lead to preventive treatments, Danish researchers say.

One in 10 women experiences a pregnancy loss, with the number even higher in countries where pregnancies increasingly occur later in a woman's childbearing years.

Pregnancy test kits sit next to a half empty shelf in a drug store in Annapolis, Maryland, on July 6, 2022. A blood test taken after a miscarriage suffered as early as week five of pregnancy can help explain why it occurred and in some cases lead to preventative treatments, Danish researchers say. One in 10 women experience pregnancy loss, with the number even higher in countries where pregnancies increasingly occur later in a woman's childbearing years. Danish gynecologist Henriette Svarre Nielsen of Hvidovre hospital near Copenhagen and her team of researchers recently published a study in British journal The Lancet showing that a blood sample taken from the mother soon after a miscarriage as early as the fifth week of pregnancy can determine whether the foetus had a chromosome anomaly. In Denmark, such tests are usually only offered after a woman has suffered three miscarriages, and only if they occurred after pregnancy week 10. (Photo by Jim WATSON / AFP)
