Police in the United Kingdom are using data from period tracking apps and mass spectrometry tests conducted on blood, placenta, and urine to investigate patients who have had “unexplained” miscarriages.
Though abortion is legal in the UK, there are TRAP laws in place requiring certain conditions to be met first, paramount of which is that two separate doctors need to agree that the patient meets the criteria of the 1967 Abortion Act before any treatment can go ahead. Self-managed abortion is a criminal offense with a maximum sentence of life imprisonment in the UK, as is any abortion performed after the pregnancy has progressed passed 23 weeks and six days, unless the patient is at risk of serious physical harm or death, or the fetus has severe developmental anomalies.
I heard a good news article on unexplained miscarriages on NPR last week.
There's a correlation between having a healthy baby and the volume of the placenta. Small placentas result in loss.
Which makes sense, the placenta is passing all the oxygen and nutrients to the baby, if it fails to size up, the baby is starved of nutrients and... well...
The doctor who invented the process to measure placental volume is getting the usual pushback from established medicine though. :(
